Peach Raspberry & Pecan Crumble
Where a crisp has an oat-based topping, a crumble earns its name honestly, with its very crumbly topping that tastes like a butter pecan cookie baked on top of fresh fruits in season, in this case, juicy peaches and raspberries.

NOTES: The tapioca or potato starch serves to thicken the sauce made from the juicy fruits that cook with the sugar. If you don’t have either starch available, skip it altogether. While cornstarch might seem a viable alternative, it needs to reach boiling (221°F/100°C) to fully thicken, where the other starches don’t, and in 30 minutes you might not reach that temperature, resulting in a fruit base with a chalky taste and not fully thickened.
The crumble can be baked ahead of time, stored chilled and reheated uncovered for 20 minutes in a 300°F (150°C) oven. The crumble will keep for up to 3 days, refrigerated.
