Why it works: Flour and butter 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 ↓
Egg Sauce
Ingredients
Directions
Make the sauce
Dissolve one teaspoonful of flour in a very little cold water.
Add it to one cupful of boiling water and a piece of butter the size of an egg.
Boil this to the consistency of thick cream and keep it hot.
Finish the sauce
Beat one egg (white and yolk together).
Add one cupful of granulated sugar.
Beat until light and creamy; flavor with vanilla.
When ready for use, pour the hot mixture over the egg and sugar, beat up and serve at once.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |

| Flour | 1 cup (125g) all-purpose | 455 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Water | not in our table | 0 |

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Egg
- Adds richness and body, and its proteins set gently with heat.
- Granulated sugar
- Sweetens the sauce and adds body to the beaten mixture.
- Butter
- Adds fat for richness and a smoother mouthfeel.
The step that matters
Pouring the hot mixture over the egg and sugar. Hot liquid can curdle egg proteins if added too fast. Pour slowly while beating constantly so the egg warms gradually and stays smooth.
