Hmmm good question, Spunky.
Is there an expiration date on the bottle? Now, by a long while, do you mean years? The google machine says six months after opening is about the limit.
Olive oil is all I use - it never sits around long. You can refrigerate it, but it solidifies due to the fat content.
A LOT longer then six months. It’s been years. I guess I better throw it out. Olive oil is all I use for cooking. Cheap Walmart brand that says for cooking. It has a higher flash point than other Olive Oils. I don’t know if it would be good for salads etc.
I also have all kinds of sauces in my refrig that I bought for a special recipe and never used again. Like sweet & sour sauce, Thai paste etc. I guess I need to throw them out also.
For a few years I was doing the “Hello Fresh” meals you order online. I liked them because they supplied you with all the ingredients except oils & salt-pepper. So no waste. These meals are a bit expensive but they serve 2 and since I am 1 they last me for 2 days. So not quite as expensive that way.
