Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Silver- Skinned Onions in Cream
Ingredients
Directions
Prepare the onions
Remove skins from one quart of silver-skinned onions.
Put the onions in a saucepan, cover with boiling water, add one-half tablespoonful of salt, and boil for five minutes, then drain.
Again cover the onions with boiling salted water and cook until soft, but not broken, and drain thoroughly.
Make the sauce and serve
Melt three tablespoonfuls of butter, add three tablespoonfuls of flour, and pour in gradually one cupful of scalded milk and one-half cupful of cream.
Add the onions to the sauce and let stand for twenty minutes.
Season to taste with salt and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted with flour to form a roux that thickens the sauce and adds richness.
- Flour
- Cooked with melted butter to form a roux that thickens the milk and cream into a sauce.
- Milk
- Forms the liquid base of the sauce, which thickens as the flour starches gelatinize.
- Cream
- Adds fat and richness, giving the sauce a smoother, silkier texture.
- Silver-skinned onions
- Cooked until soft but intact, providing the main body and mild sweetness of the dish.
The step that matters
Cooking the onions until soft but not broken. Onions simmered too long lose their structure and turn mushy, while undercooked onions stay firm and sharp. Draining thoroughly matters too, because excess water thins the cream sauce.
