I feel, in the interests of fair trading, I should probably name this Blackberry Soggy, since what is so more-ish about it is its butter-fudgy topping. But since "crisp" is what these kinds of non-crumble pies are known as, I'll stick to that. Regard this as an open blueprint and use any fruit you feel like or that is to hand. For US cup measures, use the toggle at the top of the ingredients list.
