Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork tenderloin
- Provides the main protein, which firms and turns opaque as it cooks through.
- Gravy or broth
- Adds liquid and savoury flavour, keeping the diced meat moist as it cooks.
- New potatoes
- Add starch and body, soaking up the savoury liquid and making the dish more filling.
- Onion
- Softens and sweetens as it fries in butter, building a base flavour.
The step that matters
Cook thoroughly. Pork must be cooked fully through so it is safe to eat, yet overcooking dries lean tenderloin and makes it tough. Dicing small and cooking until no pink remains helps balance safety and tenderness.
