Brunswick Jelly Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

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

  2. Cream together the butter and sugar until light and fluffy.

  3. Add the egg yolks and rose water, mixing well.

  4. Gradually add flour until the dough is soft but not sticky.

  5. Roll out the dough and cut into cookie shapes.

Bake and finish

  1. Bake until lightly golden.

  2. Once baked, spread apple jelly on top of each piece.

  3. Prepare frosting from the egg whites and spread it over the jelly.

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

What each ingredient does

Butter
Creams with sugar to give the dough a light, tender crumb and rich flavor.
Sugar
Creams with butter to add sweetness and help the dough brown lightly.
Egg yolks
Add richness, color and binding so the dough holds its shape.
Flour
Provides the structure that sets the dough once baked.
Apple jelly
Adds a sweet, fruity layer and moisture on top of the baked pieces.

The step that matters

Adding flour gradually. Adding flour in stages lets you judge the dough's texture. Too much flour makes the dough tough and dry, which makes it hard to roll and cut cleanly.

Swap the apple

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

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