I used an old Bon Appetit recipe circa 1999 for pear maple crumble with a few substitutions. I used pecans instead of walnuts, a few pinches of fresh ginger(zing!) and less maple syrup since the pears were so juicy.
What is the difference between a crisp and crumble anyways?
Crisp — a deep-dish fruit dessert made with a crumb or streusel topping and baked. The main difference I see is that this one contains oats in most instances.
Crumble — a British dessert in which raw fruit is topped with a crumbly pastry mixture and baked. One reference says a crumble is like a crisp, but not as rich.
