@Green Witch,
I think I'll pour a nice glass of wine. I'm waiting for my homemade borlotti bean chile to thaw...
Speaking of biochemistry, I remember reading that it is not so much fat that causes fatness (within reason, of course), as the metabolism of too many unnecessary carbohydrates - and, me, I choose to use monosaturated oils primarily and occasionally go to town on some good fatty cheese. What wards me away from it is expense. I might use real lard once in a while if I could easily get to the shop that renders it.. I haven't bought anything with transfat in it for at least twenty years, maybe more.
Oh, wait, I lied. I have bought potato chips within that time. I've mostly entirely totally completely and fully weaned myself from them (she protests too much), not least because most now taste worse than they used to with the trans fats, but also because they are stupid for me to eat. Alternately, I'm toying with making my own sweet potato crisps..
