Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
Beat together the eggs and sugar until well combined.
In a saucepan, cook the molasses and butter until melted.
Pour the molasses mixture into the egg mixture and beat well.
Add vanilla extract to taste.
Bake
Spread the mixture onto the pastry and bake until set.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Set the custard as they cook, giving it body and a firm, sliceable texture.
- Sugar
- Adds sweetness and helps give the custard a smooth, tender texture.
- Molasses
- Provides the dark color, rich flavor, and sweetness that define the custard.
- Butter
- Adds fat for a smooth, rich mouthfeel and a silkier texture.
The step that matters
Bake until set. Egg proteins coagulate as they heat, so the custard firms up at a set temperature. Underbaking leaves it runny, while overbaking can make it weep, curdle, or turn rubbery.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Applefits less well
Fit is the average pairing score against egg, sugar, molasses, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
