Chocolate 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 batter

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

  2. Sift the flour.

  3. In a bowl, cream the butter and sugar together.

  4. Add the eggs and sweet milk, mixing well.

  5. Combine the dry ingredients: flour, cream of tartar, and baking soda.

  6. Gradually add the dry mixture to the wet ingredients, mixing until smooth.

Bake and make the icing

  1. Pour the batter into jelly pans and bake until a toothpick comes out clean.

  2. For the icing, combine sugar, sweet milk, and chocolate in a saucepan.

  3. Bring to a boil and cook until it thickens enough to spread between layers.

  4. Add lemon extract to the icing and mix well.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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 trap air and give the cake a tender, rich crumb.
Eggs
Add structure and richness, helping the batter set as it bakes.
Flour
Forms the structure of the cake once its proteins set in the oven.
Cream of tartar
Acidic powder that works with baking soda to lift the batter and stabilize its texture.
Baking soda
Reacts with the acid in the batter to produce gas that makes the cake rise.
Chocolate
Adds flavor and body to the icing, which thickens as it cooks.

The step that matters

Cooking the icing until it thickens. Sugar, milk and chocolate must boil long enough for the mixture to thicken to a spreadable consistency. Too little cooking leaves a runny icing that will not hold between layers, while overcooking can make it stiff and grainy as it cools.
