Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare the dough

  1. Dissolve the yeast in lukewarm milk and sugar. Set in a warm place to rise.

  2. Cream the clarified butter, fresh butter, powdered sugar, lemon rind, salt, and mace.

  3. Add the beaten egg yolks, raised yeast, flour, and beaten egg whites. Beat until the batter falls from the spoon.

  4. Set aside to rise until light.

Shape and fill

  1. Turn out onto a floured board and pat to ½ inch thick.

  2. Cut with a small biscuit cutter and place on buttered tins about 1 inch apart.

  3. Brush with melted butter and press down the center of each to create a ridge around the edge.

  4. Fill with stewed fruit.

Bake

  1. When well risen, bake in a hot oven (400°F / 200°C).

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

What each ingredient does

Yeast
Ferments and raises the dough, giving it a light, airy crumb.
Egg yolks
Add richness, fat and tenderness to the dough.
Egg whites
Whipped into the batter to add lift and a lighter texture.
Butter
Adds fat for tenderness and flavor, and helps the pastry brown.
Flour
Provides the structure that holds the risen dough together.

The step that matters

Let the dough rise until light before shaping. Yeast needs time to produce gas and build structure; shaping or baking an under-risen dough gives dense tarts that spread poorly and rise less in the oven.

Swap the mace

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Parsleyfits better
  4. Macethe original

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