I thought this thread was going to be about cooking with homemade bone broths. I generally don't do that because we prefer broth all by itself or in regular soups; grains cooked with broth don't seem to be enjoyed as much as grains cooked with olive oil or butter and salt. To me, that's what soup is- the stuff I make myself in the crock pot!
I haven't bought canned soups in YEARS. The meat-based ones are usually not kosher, and the kosher brands of meat broths are full of MSG and other junk I won't eat or feed my family. Some of the "cream of veggie" soups are kosher, but I stopped using those when DD2 went on the Feingold Program. The few brands of "all natural soups" available aren't kosher. I have found basic chicken broth in the frozen section, but it's expensive and I'd rather make it myself. I could see buying ready-made broth if I had less time and more money.
I can't have dairy or corn, so if I made something with "cream of celery soup" I woudln't be able to eat it anyway. What's the point? If DD wants to make something with a cream sauce, she'll make a roux and add whatever spices are desired, or add cheese for cheese sauce, etc.
A few weeks ago, I was browsing through the book by the Duggars. There was a recipe in there that called for a 2lb brick of velveeta and a can of cream of something soup, with instructions to melt the "cheese" in the microwave, stir in the soup, and microwave a bit longer, then mix with pasta and some other ingredients. Reading that, I was thinking "when you're microwaving food for 20 people, is it really saving you any time over cooking a roux from scratch?" I just can't comprehend growing up with such a large family, taking turns in the kitchen, yet still not learning how to cook "real food."
