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.
Make the batter
Cream together the butter and sugar until light and fluffy.
Mix in the sour cream.
Gradually add the flour and baking soda.
Beat the eggs until light.
Fold the beaten eggs into the mixture.
Add the grated nutmeg and mix well.
Bake
Pour the batter into small tins.
Bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air, giving a light, tender crumb and rich flavour.
- Sugar
- Creams with the butter for aeration and adds sweetness and golden browning.
- Sour cream
- Adds moisture and acidity, keeping the crumb tender.
- Flour
- Provides the structure that sets as the cupcakes bake.
- Eggs
- Add structure, richness and lift when beaten and folded into the batter.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that makes the cupcakes rise.
The step that matters
Folding in the beaten eggs. Folding gently keeps the air beaten into the eggs, which helps the cupcakes rise. Vigorous stirring knocks out that air and can make the crumb dense.
