Why it works: Milk and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 12,655 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Prune Pudding
Ingredients
Directions
Cook the prunes and oatmeal
Wash the prunes.
Place the prunes in a saucepan with enough cold water to cover.
Cook the prunes until soft, about 15 minutes before done.
Add 3 tablespoons of sugar to the prunes.
Pick and wash the oatmeal groats.
In a separate saucepan, combine the oatmeal groats with ½ pint of cold water.
Cook the oatmeal in a boiling water bath for 45 minutes.
Make the custard
In another saucepan, heat the milk, remaining sugar, cinnamon, and salt.
Beat the egg yolks with a spoonful of cold milk.
Stir the beaten yolks into the warm milk until it thickens, but do not boil.
Stir in the cooked oatmeal, rusk, and prunes.
Remove the mixture from heat.
Finish and serve
Beat the egg whites with 2 tablespoons of sugar until stiff.
Gently fold the stiff egg whites into the mixture.
Serve warm, without sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prunes
- Provide sweetness, body and fruity flavor as they soften in the pudding.
- Oatmeal groats
- Thicken the pudding and give it a hearty, starchy texture as they cook.
- Eggs
- Thicken the custard when yolks are cooked, and whites are folded in for a light, airy texture.
- Milk
- Forms the custard base, providing richness and moisture that the eggs set into.
- Rusk
- Adds dry crumb that helps absorb moisture and firm up the pudding's texture.
The step that matters
Stir the beaten yolks into the warm milk without boiling. Egg yolks thicken gently as their proteins set; if the custard boils, the yolks can scramble and curdle, leaving a grainy texture.
