The OP said, let's not talk about microwaveable popcorn, but ... can we? I'd like to know what the favorites are. Sweet Baboo and I have a late-night popcorn snack during the late-night movie most nights of the week. (We figure, heck, it's pretty healthy, 3 grams of fiber, etc., if you don't count the 2 tbsp of melted butter we put on it ...)
By the way, who among you puts melted butter on microwaved popcorn, and who doesn't? Because I'm here to tell you, it was an all-new concept to me 'til a few years ago when we had some popcorn at my brother- and sister-in-laws' house. Can you believe I went through the first 40 years of my life never having seen someone add melted butter to supposedly "butter-flavored" popcorn? Have I mentioned my child-of-Depression-era-parents, large-Irish-Catholic-family upbringing? I think I have.
BID. (Katie for "but I digress.") We usually buy Pop Secret. Once recently Sweet Baboo came home with a Jewel brand of popcorn. (I could have told him not to waste his $$ at Jewel, but he didn't ask for my opinion.) The flavor was good; the popped-unpopped ratio was no better. I didn't pay so I don't know how the cost compared.
Another question for all: do you have, and if so do you use, a "popcorn" button on your microwave? We use it and it seems to have good timing, though it doesn't guarantee no unpopped kernels. But then, adding another 5 or 10 seconds afterwards doesn't seem to help either.
You might be wondering how someone with a child-of-Depression-era-parents, large-Irish-Catholic-family upbringing wound up with a microwave with a "popcorn" button on it. All's I'll say is that I went out of town for work and somehow Sweet Baboo burned up the workhorse prototype microwave I'd relied on for 20 years and had to buy a new one before I came back. Grrr.
