Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork tenderloin
- Forms the main body of the dish; cooking it through sets its protein so it turns firm and opaque.
- Butter
- Carries fat for cooking the onion and pork and gives the sauce a rich, smooth base.
- Horseradish
- Supplies the sharp, pungent flavour that defines the sauce.
- Vinegar
- Adds acidity that brightens the pan juices and balances the rich butter.
The step that matters
Cook the pork thoroughly. Pork tenderloin is lean, so it can dry out quickly. Cooking it fully for the stated time, then reducing the heat, helps it stay safe to eat without turning tough.
Swap the horseradish
How well each one fits the dish's main ingredients (pork, butter, onion, sauce, vinegar):
