You can use any nut for this recipe. I think it would also be great with pecans (raw or toasted). Make sure if you buy the toasted nuts, that they haven't been toasted or roasted in oil. If you do it yourself you can roast them in the oven at 350° for 8 minutes. Or toast them in a skillet. [br]I think this crumble is better the second day. So, if you can, plan on making it the day before you want to serve it. This will allow all of the flavors to marry.
