Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a saucepan, warm the butter, sugar, and molasses slightly without melting.
Beat the mixture well for 10 minutes.
Add the chopped ginger and mace, then gradually mix in the sour cream or milk.
Sift the baking soda with the flour twice and add to the mixture.
Bake
Fill buttered and floured gem pans two-thirds full.
Bake in a hot oven at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the gems together as they bake.
- Baking soda
- Reacts with the acidic molasses and sour cream to produce gas that lifts the batter.
- Molasses
- Adds dark color, moisture, and a deep sweet flavor to the batter.
- Sour cream or milk
- Moistens the batter and, with sour cream, adds acidity that activates the baking soda.
- Butter
- Adds fat for tenderness and a rich flavor.
The step that matters
Warm the butter, sugar, and molasses without melting. Gentle warming dissolves the sugar and softens the butter so it blends evenly into the batter. Overheating can separate the fat and make the texture greasy or uneven.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, cream, molasses, ginger, flour):
- Cinnamonfits better
- Nutmegfits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against butter, sugar, cream, molasses, ginger, flour. Candidates are from the same food group and used in at least 100 recipes.
