Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the breadcrumbs swell in and thicken.
- Breadcrumbs
- Absorb the hot milk and swell, thickening the sauce to a smooth consistency.
- Butter
- Adds fat for a rich mouthfeel and a silkier finish.
- Cream
- Adds richness and smoothness to the finished sauce.
- Onion
- Releases aromatic flavour into the milk as it heats.
- Peppercorns
- Infuse the milk with a gentle peppery aroma.
The step that matters
Cooking the breadcrumbs in the milk. Once breadcrumbs go in, the milk can scorch on the base of the pan and the sauce can turn lumpy or gluey if it is not stirred. Keep the heat moderate and stir so the crumbs swell evenly and the starch thickens the milk smoothly.
Swap the onion
How well each one fits the dish's main ingredients (butter, milk, cream):
- Potatofits better
- Leekfits about as well
- Onionthe original
- Asparagusfits about as well
Fit is the average pairing score against butter, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
