Dough & Pastry 3:2:1

Pie Crust Calculator

Make exactly the pie dough you need for an 8- to 10-inch pie, a deep-dish, a tart or a galette, single or double crust, with all butter, half shortening or lard, and how big to roll it.

How to use it

  1. Choose the pie or tart and how many.
  2. Pick single crust, double crust or lattice, and your fat.
  3. Mix with very cold fat and ice water, chill, then roll each disk to the size shown.

How it works

Classic pie dough follows a 3-2-1 ratio by weight: 3 parts flour, 2 parts fat and 1 part ice water. A 9-inch single crust takes about 300 g of dough; other pies scale by the area of dough they need, and a lattice uses about three quarters of a top crust.

Butter gives the best flavor and flakiest layers; shortening and lard make dough more tender and easier to handle. Salt is about 1% of the flour, and a little sugar suits sweet pies.

Assumptions and limits

  • Water is a range: flour and humidity change how much the dough needs.
  • Sizes are standard metal or glass pie plates and fluted tart pans.

Tips

  • Freeze the cubed butter for 15 minutes before mixing.
  • Leave pea-size pieces of fat in the dough; they make the flakes.
  • Rest the dough at least an hour so it rolls without shrinking.

Questions

How much pie dough for a 9-inch double crust?

About 600 g of dough: 2½ cups (300 g) flour, 200 g fat and about 100 g ice water, divided into two disks.

What is the 3-2-1 pie dough ratio?

3 parts flour, 2 parts fat and 1 part water by weight, the classic formula for flaky pie crust.

How big should I roll pie dough?

About 3 inches wider than the pie plate and ⅛ inch thick: 12 inches across for a 9-inch pie.

Butter or shortening for pie crust?

Butter tastes best and flakes beautifully; shortening is more forgiving. Half and half gives you some of both.
