Sour Cream Clove Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat the oven to 350°F (175°C).

Make the batter

In a bowl, mix the beaten egg, sugar, sour cream, and dissolved baking soda.
Add the flour, ground cloves, and salt, and mix until combined.
Pour the batter into muffin pans.

Bake

Bake in the preheated oven until golden brown.

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

What each ingredient does

Egg: Binds the batter and adds structure as it sets in the oven.
Sour cream: Adds moisture and a tangy acidity that keeps the crumb tender.
Baking soda: Reacts with the sour cream's acidity to produce gas that makes the cake rise.
Flour: Forms the main structure of the cake as its proteins set during baking.
Sugar: Sweetens the cake and helps it brown during baking.
