Corn-starch Sponge 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

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

  2. Sift together the flour, sugar, corn starch, and baking powder several times, stirring thoroughly.

Make and bake

  1. Add the beaten egg whites and lemon flavoring, and mix well.

  2. Pour the batter into a long, deep pan and bake immediately.

  3. For jelly rolls, use long shallow tins, spread with jelly as soon as done, then roll up at once.

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

Egg whites
Whipped to trap air, giving the sponge its light, airy structure.
Cornstarch (in the method)
Softens the crumb, giving a more tender texture than flour alone.
Flour
Provides structure so the cake holds its shape as it sets.
Baking powder
Releases gas in the oven, helping the cake rise.
Pulverized sugar
Sweetens the cake and helps create a fine, even crumb.

The step that matters

Bake the batter immediately. Beaten egg white foam loses its air over time, and baking powder starts releasing gas once wet. Delay causes a flatter, denser sponge.

Swap the lemon

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