Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking through gently in the oven until tender.
- Butter
- Adds richness and moisture, helping the fish stay tender as it bakes.
- Tomatoes
- Provide acidity and body, thickening into the base of the sauce as they cook down.
- Onions
- Add sweetness and savory depth as they soften and thicken the sauce.
- Peas
- Add body and mild sweetness to the sauce as they cook down.
The step that matters
Bake until tender. Fish cooks quickly and turns dry and firm once overcooked, so it should be checked for tenderness and removed as soon as the flesh flakes easily.
