winter is great season to forage twigs for teas - sweet birch, spicebush, and sassafras are some of my favorites. and once the wood stove is going, it can be really nice to have a pot on, steeping/simmering, when you come back in from the cold.
my favorite crab apple has a yellow/orange fruit (inside and out) and would probably be a good cider apple. it’s sweet, and sour, and a bit tannic…probably not everyone’s preference, but a nice complex nibble.
have also been digging the first year roots of evening primrose when i find them.
