I used to bang the jar on the counter or with a knife until someone told me it can chip the glass. I don't want any small glass splinters in my food! I just bought this jarpop opener from Amazon, along with some more Spayway glass cleaner. Both tips from Flamingo - Thanks Flamey :)

The only kind of mayonnaise that is tolerable for warm weather is where the eggs in it have been pasteurized. Most jarred mayonnaise is pasteurized nowadays. You can home pasteurize eggs, if you want to make your own. Mayonnaise is also an excellent medium for breeding bacteria that have been introduced after the eggs have been treated, so if the potato salad is mixed with dirty (bad bacteria filled) hands, and left to sit in the sun, it's not any of the ingredients themselves that are the source of the taint, but the mayonnaise sure helps the bacteria to breed! Yoghurt is preserved milk. It can last for a very long time if kept cold and sealed, and be perfectly fine. With all of these things, it's a matter of circumstance and judgment. Children, elderly and people with compromised immune systems or delicate guts should err very far toward caution. Food you're feeding to guests should always be the best and freshest you have both for quality and for just in case. Like, I always open a new jar of mayonnaise when making chicken salad for a big group rather than risk exposing them to whatever might have been on my knife last week and transferred to my open jar. For home use, however, especially without little kids and elderly in the group, use a little sense, and use good practices with food handling. When there's a drip on the jar, do you wipe it off with your finger? If so, is your finger cleaner than a paper towel? Usually, it's going to be the towel, but there are scenarios when the finger might be cleaner. Either way, know that touching the working end of the bottle with anything is going to introduce bacteria...so is it the kind of thing that will fight foreign bacteria, or grow it? Is it going to linger in the fridge or get used up fast? Will you know who's going to find and eat it, or do you have random friends and all rooting around in your fridge? Is it worth letting the drip get the top all gummed up, not to wipe it? Being too clean can also be a problem. Your immune system needs things to attack, and was designed to survive mildly tainted foods. Dying of food poisoning used to be very common, but so was dying of anything. It's amazing what healthy people used to be able to get away with eating. I have a number of health issues, but I've never gotten food poisoning from something in a jar or bottle that had been in my fridge awhile without seeming off or moldy, nor has anyone in my family. I did get food poisoning once at a major league baseball game from a salad bought there that likely wasn't kept cold enough before sale.

I swear I saw a commercial for it while I was watching the wedding stuff last night, but I can't find it anywhere on the web site so maybe it will air next week? Blame it on the two glasses of wine I had, lol. LOL... Is that why your user name is Sleeperblues?

I Googled and the reviews on the One Touch Jar Opener are mixed. Pretty negative actually. It will only open certain types of jars and the batteries go quickly. I like the jar poppers that look like a plastic bottle opener to break the seal and those rubber rounds they give away at trade shows to twist and grip jars with. The waffle weave ones don't work as well. BB&B and places like Home Store carry the jar poppers. Here is a link that might be useful: Jar Popper
