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

What each ingredient does

Beef tenderloin: Provides the lean meat that is cooked to medium-rare and sliced for serving.
Butter: Adds fat and moisture to the meat and helps the crust brown.
Shallots: Add mild sharpness and savoury depth to the sauce base.
Avocados: Give the sauce its creamy body and smooth texture.
Mayonnaise: Adds richness and helps keep the sauce smooth and creamy.
White wine vinegar: Adds acidity that brightens the sauce and balances the richness of the avocado.

The step that matters

Checking doneness with a meat thermometer. Tenderloin is lean and overcooks quickly, so temperature is a safer guide than time. Meat keeps rising in temperature while it rests, so the 145° reading and the 15-minute stand both shape the final result.

Fit is the average pairing score against beef, pepper, butter, parsley, lemon, avocado, sauce. 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).
