A bit tricky in the damp environment on Erraid. Still worth trying.

Herbs, crab apples, seeds from nettles (healthy and nice in muesli), seewead (book Miek Zwamborn).

Crab apple

Rinse, cut and dry them on the fireplace. Make sure they’re thoroughly dry. Don’t store the for too long. Eat in muesli or use in apple crumble.

It says one can also use them for making apple juice or jelly. Worth a try….
