The best yellow popcorn I've had was home grown by a friend's sister. I got a jar of it, but I don't recall how long after the harvest it was, not too long though. Had a natural sweetness to it I haven't tasted since.
These days with a restricted diet I make popcorn in the microwave in a bowl with a cover. Don't use any fat or salt, but finding the right pop corn was crucial. I can enjoy the taste of the corn, so maybe i'm lucky that way.
All the talk about coconut oil reminded me of a time as a young man when I met this young woman who said her favorite way to make pop corn was on the stove using rendered duck fat. I thought to myself, "this is the girl for me". Alas, that didn't turn out to be true , but we had very good times finding that out about one another.
