#quickreference To know whether your apple tree is a standard type or a crabapple, measure the fruits. This size or smaller -- 2" in American, LOL -- and you have yourself a crab apple. Any larger and it is the regular kind.
This is a find from the grocery store: a maple-brown-sugar-and-crabapple pie. Soooooo good. I confess I am deeply suspicious of the apples; the slices are about twice the size of the biggest crabapple I have ever seen. But they are extremely tart. Must. Find. Recipe. #yum
