Vanilla Wafers

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat your oven to 400°F (200°C).

Make the dough

  1. In a bowl, mix the sugar and melted butter until combined.

  2. Add the egg, milk, baking soda, cream of tartar, and vanilla, and mix well.

  3. Gradually add flour until the dough is stiff enough to roll out thinly.

Shape and bake

  1. Roll the dough very thin and cut into desired shapes.

  2. Bake for no longer than five minutes.

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

What each ingredient does

Butter
Adds richness and tenderness, and helps the sugar blend into a smooth base.
Baking soda
Reacts with the acid in the dough to produce gas that lightens the wafers.
Cream of tartar
Acts as an acid that works with baking soda to help the wafers rise and brown.
Flour
Provides the structure that lets the dough be rolled very thin and hold its shape.
Egg
Binds the dough and adds structure as it sets in the oven.

The step that matters

Bake for no longer than five minutes. Thin dough cooks very quickly, and extra minutes dry it out and brown it past the pale golden color expected of a vanilla wafer.
