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

What each ingredient does

Onion
Softens and sweetens as it sautés, building the base flavor of the sauce.
Cornstarch
Thickens the sauce into a smooth, coating consistency when mixed with cold water first.
V-8 juice
Adds liquid, tomato-vegetable body and acidity to the sauce.
Chicken stock
Forms the liquid base, and its reduction concentrates flavor after deglazing the pan.

The step that matters

Thicken with cornstarch. Cornstarch must be mixed with cold water into a slurry before adding, because raw starch clumps if dropped into hot liquid. Starch thickens only when the liquid is hot enough to gelatinize it, so the sauce should be simmering as it is added.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (olive, garlic, pepper, chicken):

  1. Tomatobetter flavor fit
  2. Capsicumbetter flavor fit
  3. Spinachabout as good a flavor fit
  4. Onionthe original

Fit is the average pairing score against olive, garlic, pepper, chicken. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
