Streusel

Directions

1. 1
   To make the streusel: Put the flour, sugar and salt in a medium bowl and mix everything together by running the ingredients through your fingers.
2. 2
   Drop in the butter and squeeze and rub the cubes into the mixture until you have a sandy mix.
3. 3
   If you press a little streusel together, you'll get lumps, which is just what you want.
4. 4
   Drizzle the vanilla over the streusel and toss, squeeze and rub to distribute it.
5. 5
   Cover the bowl and chill the streusel until needed.
6. 6
