Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mild onions
Break down into a pulp that forms the body and sweetness of the sauce.
Butter
Cooks the onions gently and adds richness and a silky mouthfeel.
Veal gravy
Adds savory depth and liquid to thin the onion pulp into a sauce.
Boiling cream
Adds fat and smoothness, rounding out the sauce just before serving.

The step that matters

Stewing the onions over low heat. Onions cooked slowly over low heat soften and release their sugars for gentle browning and sweetness. High heat can scorch them, leaving bitter flavors and an uneven pulp.

Swap the onion

How well each one fits the dish's main ingredients (butter, veal, cream):

  2. Potatofits about as well
  3. Leekfits about as well
  4. Asparagusfits less well

Fit is the average pairing score against butter, veal, cream. Candidates are from the same food group and used in at least 100 recipes.
