This crab apple jelly recipe is simple, and crab apples contain so much pectin that it usually sets very well. In fact, I add a little crab apple to my marmalade to help it set. You can use any crab apple, but among the best are: Malus ‘Harry Baker’, Malus Jelly King (=‘Mattfru’), Malus ‘Dartmouth’, Malus ‘John Downie’ and Malus x robusta ‘Dolgo’.
