Gas ovens vs electric ovens - Please explain preferences
Comments (21)In my last house I had an old gas double oven and a separate gas cooktop. I am a baker first and a cook 2nd. I always had beautiful cakes, cookies, breads etc. When we redid the kitchen I was disappointed not to have the gas double oven option (we were not looking at high end items -- I got GE profile electric double ovens and gas cooktop) At no point during that remodel did I think (or be told) that you can't bake cookies, cakes etc well in gas ovens. Now with this remodel all I am hearing is the difference in baking with gas is sub par if you want to do cakes cookies etc. and it is making me 2nd guess myself even though until the last couple of years I have always had a gas oven. The good news is is that I think the Wolf DF is really ugly and I really like the looks of the 48" AG -- plus it is cheaper -- and I know I can cook well in it -- only thing that is really holding me up is the no self clean -- I am just not an oven cleaner :-(...See Morebaked and roasted - better in gas or electric?
Comments (32)caliloo - Do you have Craigslist in your area? When we first started the remodel I got a JennAir Dual Fuel Slide-In Range (JDS8860BDP). I hated it so I sold it for a lot less then I paid for it on Craigslist. It was only a few months old but I didn't like the different BTU burners. I wanted them all the same like on the Wolf. And talk about being a rocket scientist, you had to be to use the control panel. It had so many features that I would never use. All I wanted was a simple bake, broil and convection like I have now. I don't need nor want all those other features. And I had heard bad things, after I got it, about how the computer in the control panel keeps failing and has to be replaced several times costing hundreds of dollars. Maybe they fixed that. Plus ours was built crooked and the door didn't hang right. We didn't notice till it was being installed. It was a disaster. The cabinets had to be removed and reinstalled and extra trim pieces added. And it stuck out into the room 7 inches because of the curved front. Like I said, I hated it! So do your research and read everything you can about all the ranges out there. Check out both the Kitchen and Appliances forums and use the search box to get more information on any range you are looking at. Good luck.

Comments (43)Another take on the induction question with a little sprinkle of humor. https://www.eevblog.com/forum/chat/induction-cooking-emf-magnitude-vs-other-things-missus-is-a-bit-concerned/ Tim says, Ugh... If she's worried about cancer... dump her now? There's no convincing someone like that, to understand statistics and significance. At least that I've heard of. If you're looking for the opinion of an EE, I would gladly give you my opinion on the subject -- if you'd like it in writing, I can even sell your wife a certificate saying as much! Maybe that wouldn't help. I don't know. What are we talking about, anyway? Cooktops aren't always-on. They're either off until turned on, or pulsing infrequently to check if a pot is present. The RMS EMF at the surface is not very large either way, when not actively heating something. When heating, it's only large under the work being heated. EMF drops off rapidly with distance. If your wife is so strange that she finds it enjoyable to read books while laying over the cooktop, I might be concerned, but only for mental health reasons, not for EMF reasons. Or if shoving her head towards a pot that's being heated, I would be more concerned for safety reasons, and then mental health reasons... There are biological effects of EMF, but not at these field strengths. Not by orders of magnitude. The primary effect is simply dumb old heating. Diathermy machines, microwave ovens, and the military's ADS, operate on this mechanism. There is no biological effect beyond heating (obviously, too much heat and you cause burns, but that's not unique to EMF). Strong pulsed fields can induce voltages in neural tissue (transcranial magnetic stimulation), which do have direct neural effects, but these are temporary. Anything that produces fields with too little energy to cause noticeable heating, or pulse peaks strong enough to cause noticeable induction, is completely and utterly inconsequential. Example: ESD can have quite large (peak) EMF, but is over very quickly, and delivers very little energy (on a human scale). (Anyway, sparks are well known to cause people to involuntarily jump or twitch. But again, that's just a neural stimulation thing, nothing more.)...See MoreTrying to decide between a gas vs electric oven, any advise please?
Comments (9)There are a few differences in gas and electric ovens. You will find that chefs and manufacturers would say gas is “moist” heat because water is a byproduct of combustion and so electric must be dry. The problem is they are not looking at the whole oven and the process of cooking. What are sources of moisture and what happens to it? There is moisture released with the combustion of gas. Food also produces quite a bit of moisture in the cooking process. I read just a couple of weeks ago on the Miele website that a cake baking provides the equivalent of the 30 % steam setting on their steam oven. Imagine how much moisture is produced with some other foods. Gas ovens have a much bigger vent to vent the products of combustion and moisture from food. You have a lot more movement of air through a gas oven while an electric oven has a much smaller vent, holding on to the moisture produced by the food. Reading cooking and baking forums you hear these comments over and over. Gas ovens put more heat and moisture into the kitchen. Gas ovens are great for roasting and browning. If you read about the Maillard reaction, you will see that you must have drying to allow the temperature of the surface to rise and browning chemical reactions to take place. Some bread bakers want to add steam at the beginning of baking to promote starch gelatinization for a specific type of crust. They report it is much more difficult to keep added steam in a gas oven. Baking is a complex interaction of variables so it is difficult to make hard and fast rules because you only have to change one or two of the variables and get a different result. Some bakers say that cakes don’t rise as well if they had an electric oven and go to gas. Sometimes they say gas produces a dry looking cake. This again has to do with starch gelatinization being prolonged in an electric oven giving a little longer rise. This doesn’t mean you can’t bake in gas. I think some recipes work well in gas and over the years, you keep recipes that work and discard those that don’t. Cake mixes are formulated to work in different conditions so work with both. Things with more sugar may also show more difference. Eveness in baking is tricky. That’s what everybody wants. Convection is marketed as the answer to even heat but it can make air currents that make hot spots. The fan is drying to the surface of what you are baking or roasting so that part browns quicker if it gets exposed to an air current. Some companies try to fix that by having two fans, baffles or a reversing fan. Some ovens have a variable speed fan. The fan does change the direction of heat so that it comes from more directions instead of the bottom. Many recipes for cakes and pies were developed with the heat coming from the bottom. There are very expensive electric ovens that don’t have it right and my DILs Bosch gas oven is pretty good. My Electrolux oven is pretty even but has other problems. Aside from the the nature of the heat, electric ovens can have more control. They may have a third element (true or European convection) and direct heat from the top or bottom, more from the top for roasting. A few gas ovens may have these features now. They can have very tight control of temperature, maybe +/- 2F but I’m not sure how much that matters. More important to me is the range of temperature. My current oven has 80-450F and the fan can blow with the heat off or up to 450F. Some ovens only go as low as 225F. Both of my ovens have slow or fast fan speed. I know bakers that use gas and electric. Some commercial ovens have steam injectors and ventilators to control humidity. Gas broilers come come in two forms, the first is a conventional one that doesn’t get that hot. There are also gas infrared broilers that heat evenly and get hot but might be smaller....See Moreannab6
