Step 1

Grate cold butter into a large bowl. Alternately, you can dice it small.

Step 2

Add sugar: use all brown or all white or a combination to make 2/3 cup. Use whatever combination you like (I like using 1/3 cup each brown and white).

Step 3

Add flour and then, using a pastry cutter, work the butter into the flour and sugar until the mixture forms coarse crumbs.

Step 4

Use crumble as recipe directs, on a fruit pie or on muffins or coffee cake. Bake as directed in recipe.
