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 ↓
Simple Salad Dressing
Ingredients
Directions
Combine one tablespoonful sugar, half teaspoonful flour, one teaspoonful salt, dash of red pepper, and celery salt, then stir all together well.
Add one beaten egg, four tablespoonfuls vinegar, and two tablespoonfuls water.
Boil a minute or two while stirring constantly until it becomes a paste.
Add butter the size of a walnut, and cream or olive oil enough to thin it to a proper consistency.
Add a little mustard if desired.
Nutrition, whole recipe (rough)

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as it cooks and helps bind it into a smooth paste.
- Flour
- Thickens the mixture so it turns into a paste when boiled.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
- Butter
- Adds richness and a smoother, creamier texture to the dressing.
The step that matters
Boil while stirring constantly. Egg proteins and starch thicken the mixture as it heats, but if it sits still it can scorch or turn lumpy. Constant stirring keeps the heat even so it becomes a smooth paste.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, flour, vinegar, tea, egg, butter, pepper):
- Almondfits about as well
- Chestnutfits about as well
- Walnutthe original
- Beansfits about as well
Fit is the average pairing score against sugar, flour, vinegar, tea, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
