Appelmoes, basically meaning 'apple mush' in Dutch, is a popular (side) dish made with, well, you probably guessed it: apples. Traditionally, in The Netherlands, goudreinet (‘golden rennet’, also called goudreinette or Belle de Boskoop) apples are used to make appelmoes, since their tart flavour, firm texture and dry and rough peel make them unpopular as an eating apple.
