Why it works: Butter and flour 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 ↓
Thick Veloute Sauce
Ingredients
Directions
Make the roux
Melt the butter in a saucepan over medium heat.
Add the flour and stir continuously to form a roux, being careful not to scorch it.
Finish the sauce
Gradually whisk in the hot chicken stock until smooth.
Cook until the sauce thickens, then season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that coats the flour to form the roux and carries rich, savory flavor.
- Flour
- Starch thickener that swells in the hot liquid to give the sauce body.
- Chicken stock
- Liquid that hydrates the flour starch and forms the sauce's base.
The step that matters
Gradually whisk in the hot chicken stock until smooth.. The flour's starch granules swell and thicken as liquid is added. Adding the stock gradually while whisking keeps the starch evenly dispersed, which prevents lumps and gives a smooth sauce.
