Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the dough

  1. In a bowl, cream together the butter and brown sugar.

  2. Add the egg yolks and 1 egg white, mixing well.

  3. Stir in the flour and baking powder until combined.

Shape and bake

  1. Roll out the dough thinly.

  2. Spread the beaten egg white over the dough.

  3. Sprinkle with ground cinnamon and granulated sugar.

  4. Cut into squares and bake until golden.

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

What each ingredient does

Butter
Adds fat that makes the dough rich and tender.
Light brown sugar
Adds sweetness and moisture, and helps the surface brown.
Eggs
Bind the dough and add richness; the beaten white helps the topping stick.
Flour
Provides the structure that holds the cookies together as they bake.
Baking powder
Releases gas in the oven so the dough lifts slightly and stays light.

The step that matters

Cut into squares and bake until golden. Sugar darkens quickly, so the tarts can scorch or turn hard and dry if left in the oven past golden. Check them near the end of baking.

Swap the cinnamon

How well each one fits the dish's main ingredients (sugar, butter, egg, flour):

  1. Cinnamonthe original
  2. Nutmegfits about as well
  3. Jalapenofits less well
  4. Capersfits less well

Fit is the average pairing score against sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
