......and a whole lot has changed in the culinary world along the way.
One of the positive changes is the greater availability of heritage livestock breeds. People are raising all sorts of old-time breeds, in poultry, hogs, and even cows.
I'd say interest in heritage livestock right now is about where heirloom vegetables were in the early to mid-90s; that is, it's sort of an agricultural subculture with ever growing numbers of participants. If it follows the same progression, we're sure to see many of those varieties mainstreamed in the near future. Meanwhile, if you search around, you can find them.
Shromgirl, I know, has been very active on the hog end, and can probably make references. Poultry probably is even bigger, in terms of breeders, because there were so many more varieties, and they require less room.
All in all, it's a great time for real food.
