A Question for the Kettle Users

All the talk about coffee and kettles leaves me with a few questions. Do you leave the water in the kettle or empty it after each use and let it dry?

What about the water? Tap? Spring? Filtered? Does it matter? I do have somewhat hard water that can leave deposits. Please share your experience. Thanks.

    Always empty completely and leave the top open to dry out. I always measure in exactly the amount I'm going to use too, so there's no waste.

    I use distilled water and have zero scale.

    I don't like the idea of leaving water in the kettle, whether it's stovetop or electric - bacteria can grow in there 😕

    Another 'Open-Kettle' Canning question

    Q

    Comments (14)
    TL, just to give you an idea, botulinum toxin is a million times more toxic (by concentration needed to kill you) than strychnine, which is in rat poison. So if you got splashed while opening a jar of soup to boil it, and that splash touched your mouth, you could die. Maybe. Obviously you have safely eaten the soup before, but the stakes are high and you may not always get away with it. I agree that it is important to keep a good relationship with your MIL (especially since she is an in-law and you don't have a lifelong relationship). When I got interested in dog training, my mom picked me up a dog training book for $1 from the used rack at the library. It was a methodology I don't agree with, so I said thanks and told her I didn't agree with it. She said she would give it back, and I said it would actually be more useful to toss it so nobody else subjects their dog to this method (which I felt was very mildly inhumane). But that really hurt her feelings: she bought me a book and I threw it away! I have really had to work on being more sensitive to my relationships than my beliefs! So you might decide you need to politely tell her that you don't want your kids (if applicable) eating her canned soup anymore, and ask her if she could freeze some for you instead, or if you could do a joint session with her soup and your new pressure canner (uh, assuming it matches a tested recipe). It sounds like you are aware of both the safety issues and the relationship issues, so you are all set to proceed carefully and do a great job. Happy canning! Melissa

    Question for Tide PurClean Users

    Q

    The Tide boost pods are excellent. Reviewed just did a comparison with it next to OxiClean, and they beat it and LCB. We often times have blood on our bed sheets due to bloody noses or the dog. The dog has lick granulomas that he insists on sharing with our bed sheets and comforters, despite not being allowed on our beds. I have used PurClean and STPP with hot water on the comforters and had no issues removing all of the blood. Yes, hot water and blood aren't a mix. But the PurClean worked its magic. White sheets and matress pads get Tide plus Bleach powder. Sheets aren't a problem and come clean, but the matress pads typically have some oxidized blood remaining.

    I have a glass kettle with a tea basket insert. I don't drink coffee. I use it only for tea. It replaced an electric iced tea maker on which the plastic parts were deteriorating after many years of use. Get the water boiling, let it cool a moment, steep the tea. Make a gallon of cold/iced from it, so not done every day. I'm on well water, filtered (not softened) to whatever extent the refrigerator provides. There's mineral residue on bottom of the carafe at every use, which I clean with a dash-of-vinegar soak after every use.

    I was thinking about ”endlessly reboiled water”.

    The water in my kettle is used for other things besides boiling.

    I use it to water houseplants, (well, three stalks of lucky bamboo and one small plant on the kitchen window ledge), I top up the dog bowl, I use it in cooking. ( I measure cold water directly from the kettle. )I think sometimes, I can go through a full kettle, and none of it has been boiled.

    It’s easier to me, to carry the kettle around the house, rather than lug the items to the sink.

    We have one kettle and it only boils water. Tea is never made in it. If it were it would affect the taste of the myriad other things we boil water for. And the kettle is required so frequently it can't be tied being used as a teapot. We often want to make tea and coffee at the same time.

    Our kettle holds .8 liters and both my wife and I tend to fill it to about the level needed for one cup (mama bear and papa bear style, her cup and Hario filter cone are smaller than the ones I use) . What's left after use might be 1/2 inch of water, not worth doing anything with. It's used only in the morning, we don't drink tea and rarely use it to make coffee later in the day.

    We use spring water. It's funny because though we always use the same brand (one whose flavor we like), what winds up getting into the products sold in my area seems to vary and have different sources from one time to another. Sometimes, the batch leaves the stainless steel kettle shiny clean for weeks at a time. Other times, there's enough of a hard water build-up that a vinegar treatment is needed every few weeks.

    I have nothing against tap water, I just like better the coffee flavor the spring water produces. I drink tap water AND spring water during the day when home or when away, it depends what's most convenient.

    I have THIS Alessi tea kettle. It's high grade stainless steel....it doesn't scale. We have well water @ this house, but the last house was tap water. My husband drinks a pot of tea every day, usually Earl Grey. He prefers a pyrex measuring cup to boil his water in the microwave. He carries his big Yeti mug around with him ALL day....drinking tea.

    Our water causes scale regardless of the material the kettle is made of. We live on limestone and chalk geology and our water is very hard. It's an issue for plumbing, central heating and water boilers as well as kettles. Stove top kettles are rare here. Electric kettles are the norm and they fur up more than stove top.

    Judging just from my own observations, I think it's a minority of US homes that have electric kettles. Electric kettles are growing in popularity but slowly. Most homes historically have had stovetop tea kettles.

    I think there's another factor at work that contributes to the difference aside from the obvious reason of tea being more entrenched in British culture. (and in Canada, by extension) than in the US.

    Electrical power at wall sockets in most of the world except for the US is 240 volts, not the weaker 120 volt setting that prevails in North America. A water kettle at the higher voltage can bring water to a boil much more quickly than one using a 120volt outlet. Additionally, boiling water on a stove top of the traditional gas or electric resistance kinds is also much slower.

    So, if you want a few cups of water brought up to a boiling temperature with haste, and likely in the most energy efficient manner, a 240v kettle is what you need.

    240v circuits are known in North America, they're made by putting two 120 circuits together. They're most commonly seen as the wiring for electric water heaters, electric clothes dryers and electric resistance cooktops/ovens. A European 240v kettle is allowed and can used by having an electrician set up a 240v wall socket. North American approved sockets and changing the plugs on the appliance to approved types must be done. Few moving here from abroad or those living here who are impatient to boil water bother to do so. Though I once knew one inbound emigrating Brit who did have it done.

    murraysmom Zone 6a OH thanked Elmer J Fudd
  • last month

    Elmer, the difference in electrical socket power doesn't explain the prevalence of electric kettles in Canada vs the US, which share the same power sockets. (And most of the world uses 220 V, not 240 V.)

    We have an electric kettle which is sort of like a kettle with its own hot plate but never use it. We also have a metal kettle that my husband uses for his tea and coffee. Since our well water is filtered and softened we dont have scale or iron problems. That would be our biggie here as we have dissolved iron without the water system. My husband will leave water in his kettle. We are wired for a wall water boiler(220)downstairs but never installed it. It is sittling in a box under the stairs.

    I dont like to use distilled for coffee. Distilled water tastes flat to me.

    FWIW, I understand that any amount of dissolved minerals in water generally are in quantities that are too low to make that much difference in nutrition. Our city adds stuff to the water - both minerals for 'flavor' and sanitary agents that I prefer to avoid, and newer studies have shown microplastics to be present in both bottled and tap water. I've been using distilled water for decades now.

    I think a better way to get more minerals and nutrients in one's diet is to eat lots of vegetables and fruits.

The kettle has mineral deposits on the bottom(tap water), and once in a while I boil some vinegar in it. I only use distilled water in the electric herbal fragrant dispenser so it’s been maintenance free.

    " a cheap source of useful nutrients "

    Sure, useful nutrients are important for those whose eating habits or health lead to having deficiencies.

    Do you have deficiencies or would you but for drinking water of a particular source?

    There's a difference between saying something is useful as a truism, without it also being implied that supplementation is necessary or required for all in all circumstances.

    Ours is a glass kettle with a thin flat bottom that sits on a base that holds the heating element.

    We use well water from a tap that has some minerals and leaves some residue but it hasn't caused buildup on our kettle.

    Son uses quite an amount of water to make soups and stews and I usually a smaller amount for pour-through coffee or oatmeal porridge with milk added for the porridge. I pour unneeded water into a bottle, but we don't empty residue after every use.

    No trouble so far.

    We have a metal kettle that we could use on our electric stove: I think it's in the basement.

    I inherited an electric kettle........my first experience with one. IMO, it may be the best thing since sliced bread!! I've used it daily for the past two years and often multiple times a day, depending on my needs. It is very fast, turns itself off when it reaches a boil and has yet to develop any significant scale, even with our naturally hard water.

    It is also one of the least expensive models available. If it decided to stop working, I'd replace with the same in a heartbeat,

    Sounds as if some of the electric kettles people have tried haven't been good examples. They should be able to boil any quantity of water providing the base is covered, they should switch off immediately once boiling, they shouldn't feel warm unless they've just boiled and they should last for years.


    Another advantage is that they don't take up space on the hob when you're cooking. Boiling or very hot water is often needed when all the rings are in use.

    I use a stovetop whistling kettle for tea. Tap water always--our water is really good. My 10 year-old bathroom faucets still look like they are fresh out of the box! I like it too, because I use an electric perk coffee pot (cretin, I know), but I can light my gas range with a match in case of a power outage to make a Melitta pour over . I wipe the spout of the kettle when I empty it, leave the spout cap open, and put it on the stove to cool. My kettles last for years. When the whistle breaks, I get another. I just make sure that it is all metal. I would think that the kettles with plastic on the spouts would experience meltdown.

    We use a stainless, polished exterior, gooseneck kettle but empty it and put it away after use. We have delicious deep well water that comes from our tap, but DH has been using bottled spring (not distilled water) bc our well water is a bit high in arsenic and old lace.

    As I understand it, good tasting water wants to have some (?usually naturally occurring) minerals disolved in it. Distilled water lacks flavor. Our deep well water is naturally just right regarding taste. It doesn’t leave any deposits and is abundant and we’re on a wooded hill mountainside with mostly protected land nearby.

    Growing up was a different story water-wise. There was a LOT of iron in the well water. We could not wash white clothing in it because it would discolor the white sheets or shirts. There were iron deposits everywhere — toilets, tubs, sinks. The taste of the water was awful, so we went to Rotary Club sponsored natural spring to fill the many gallon glass jugs (1950s, ’60s) for drinking and cooking. That was a PITA.

    " I boiled a litre of water in my electric kettle. It took 2.5 minutes. ".

    I filled my Hario kettle, capacity .8 liters, and it took 4.5 minutes.

    Stated another way, at 240v, a kettle requires 15 seconds per 100 cl.

    At 120V, it's 33 seconds per 100 cl.

    So half as much electrical power requires roughly twice as much time. The power output of electrical resistance is linear so this is about right.

    This ignores what may be slight power consumption differences (with wattage adjusted for voltage) of the different appliances used.

    "empty it and put it away after use." I'm afraid ours is never put away. It's on the work surface permanently as it's in use throughout the day.

    You can look up Joule's law.

    There is generally little or no element or variation of "efficiency" in electrical resistance heat of home appliances. All are similar in this regard, they're made to maximize heat output while staying within the requirements of home circuits (ie, amperage).

    And I was wrong, it's not a linear relationship, it's squared.

    Edit to add:

    Again, Toronto, to repeat an earlier exchange---I've lived overseas, had a 240v kettle, and experienced the more rapid boiling myself. Do you have any personal experience with it as I have?

    Coffee in the mornings, tea throughout the day, stock for cooking, boiling water prior to putting it on the stove for pasta, vegetables, etc. (speeds up the process), adding to casseroles, stews, soups, sauces, etc., in fact any time we need boiling or hot water for any purpose whatsoever. The kettle isn't so much 'handy', it's an integral piece of equipment, like the stove or the sink. Every student will have an electric kettle in their room, every staff room in a business will have one, every office will have one. A sine qua non for life here.
