Olallieberry Crisp (or any kind of berry crisp)

Fruit crisps have got to be one of the quickest and tastiest desserts I can think of-- especially with a scoop of ice cream or fresh whipped cream.

If you can't find olallieberries for this berry crisp, it's probably because you don't live in the Western United States. Blackberries come closest to these, but they aren't quite as tart, with a hint of sweetness.
