The architecture of a successful crisp relies heavily on the treatment of the butter. In my kitchen, I strictly adhere to using cold, cubed butter rather than melted butter for the topping. When cold butter hits the high heat of the oven, the water content evaporates to create steam pockets, resulting in a lighter, crispier texture that contrasts beautifully with the dense fruit filling.

Furthermore, the choice of thickener is critical. I utilized the framework from this strawberry rhubarb crisp recipe as a baseline, but emphasized the necessity of cornstarch over flour for the filling, as cornstarch provides a clearer, glossier finish that highlights the ruby tones of the fruit.
