Here I thought pork was in fact the least taste-neutral. Pork is one of the few meats that tastes delicious without any kind of seasoning at all. To go further I use pork fat to season othee foods.
Ok so that's probably subjective to some extent. The fat part is definitely relevant. When making vegan Mett from rice waffles (original that is spiced raw pork), I usually add a fair amount of oil to somehow get that satisfactory feeling that arises when eating fatty meat. It somehow works, but not as much as I wish. Grated dried tomatoes give some of the umami taste. But the fat is kind of special...
