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

  1. Preheat oven to 350°F (175°C).

  2. Beat the eggs in a bowl.

Make the batter

  1. Add the cream or butter and sugar, mixing well.

  2. Sift together the flour, cream of tartar, and baking soda, then add to the mixture.

  3. Flavor with lemon to taste.

Bake

  1. Pour the batter into a greased cake pan and bake until golden.

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.

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

What each ingredient does

Eggs
Provide structure and richness, helping the cake hold together as it sets.
Cream or butter
Adds fat and moisture, giving the cake a tender crumb.
Sugar
Adds sweetness and helps browning as the cake bakes.
Flour
Forms the main structure of the cake once it sets in the oven.
Cream of tartar
Acidifies the batter and works with baking soda to lift the cake.
Baking soda
Reacts with the acid in the batter to produce gas that helps the cake rise.

The step that matters

Sift together the flour, cream of tartar, and baking soda, then add to the mixture.. Baking soda and cream of tartar must be evenly distributed through the batter so the leavening reacts uniformly. Unmixed clumps can cause bitter spots or uneven rising.
