Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Castle Puddings
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.
Make the batter
Melt the butter in a basin near the fire.
Beat the eggs very well.
Mix the melted butter and sugar together, then add the eggs and lemon peel.
Stir in the flour until well combined.
Bake and serve
Butter coffee-cup sized molds with flat bottoms.
Fill the molds a little more than half full with the mixture.
Bake in a moderate oven at 350°F (175°C) for about 30 minutes.
Serve with raspberry vinegar sauce.

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
- Eggs
- Bind the batter and set into a firm, custard-like structure as they cook.
- Butter
- Adds richness and fat that keeps the pudding tender and moist.
- Flour
- Provides the starch and structure that hold the pudding together.
- Powdered sugar
- Sweetens the batter and dissolves smoothly for a fine, even texture.
- Lemon peel
- Adds bright lemon aroma without adding liquid to the batter.
The step that matters
Fill the molds only a little more than half full. The batter expands as it bakes, so overfilling can cause it to overflow or bake unevenly. Leaving room lets it rise and set properly in the oven's heat.
