Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Lemon Pudding
Ingredients
Directions
Make the filling
Mix flour with cold water until smooth, then stir in boiling water and let it thicken and boil.
In a bowl, beat together egg yolks, sugar, lemon juice, and grated rind.
Stir the boiling starch into the egg mixture.
Pour the mixture into a pie plate lined with pie crust and bake.
Top and brown
Once done, remove from oven and spread meringue made from beaten egg whites and powdered sugar on top.
Return to the oven for 2-3 minutes to brown slightly, being careful not to overbake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Thickens the boiled starch that gives the filling its body.
- Egg yolks
- Enrich and set the custard, adding richness and body to the filling.
- Egg whites
- Whipped into meringue, they form a light topping that browns in the oven.
- Powdered sugar
- Sweetens the meringue and helps it hold a stable, glossy structure.
The step that matters
Browning the meringue. Meringue needs only a brief stretch in the oven to brown slightly. Overbaking can make it weep, shrink, or toughen, and it can overcook the custard underneath.

Fit is the average pairing score against flour, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
