Dough – need to put sablé dough in the fridge

crustdoughrefrigerator

I made a sablé base for a cake last night. It was the first time I made this, so I used a basic recipe containing butter, flour, sugar, salt, baking powder and egg yolks. After everything is mixed the recipe says to put the dough in the fridge for two hours so it can rest.

I wondered why this is necessary? There is no yeast in the dough that would let it rise.

My only idea would be too cool down the butter so it can be rolled out more easily, but then I think two hours would be pretty long for the amount of dough I got out of the recipe.

Therre are actually two things that happen during the refrigerated rest period:

  • Obviously, the dough is cooled, which firms up the butter, making it easier to roll out without having it fall apart.
  • The starch granules absorb water, making the dough more cohesive, improving its texture, and making it easier to work
