Barm Crust

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. Mix flour, butter or lard, barm, and salt in a bowl.

  2. Add milk gradually until a paste forms.

Rise and shape

  1. Let the mixture rise in a warm place.

  2. Roll out the dough and use it as a crust.

Bake

  1. Bake immediately in a 400°F (200°C) oven.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the gluten network that gives the crust its structure.
Butter or lard
Coats the flour particles so the crust turns out short and tender.
Barm (yeast)
Ferments and produces gas so the dough rises and becomes light.
Milk
Hydrates the flour so the mixture binds into a workable paste.

The step that matters

Add milk gradually until a paste forms. Flour absorbs liquid at its own pace. Adding milk slowly lets you stop at a pliable paste, because too much liquid makes the dough sticky and hard to roll, and it can toughen the crust.
