Pate sablee
Instructions:
- Put the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until pale and fluffy, about 3 minutes; mix in the vanilla.
- Add the flour and the salt, and mix on medium-low speed until just combined and crumbly, about 15 seconds (do not overmix).
- Pat the dough into a disk, and wrap in plastic. Refrigerate at least 1 hour and up to 2 days, or freeze up to 1 month.
