Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Strawberry Jam 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour milk.
In a separate bowl, combine the flour, cinnamon, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the jam.
Bake and finish
Divide the batter into prepared cake pans and bake for 25-30 minutes or until a toothpick comes out clean.
Let cool before frosting with boiled icing.

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 the cake a light, tender crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Sour milk
- Its acidity reacts with the baking soda so the cake rises and stays tender.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- Jam
- Adds sweetness, moisture and strawberry flavour throughout the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture, mixing until just combined.. Overmixing once flour meets liquid develops gluten, which makes the cake tough and dense. Stop mixing as soon as the flour disappears.
