Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled fish
- Forms the main filling, providing flaky texture and savoury flavour.
- Cold potatoes
- Form the topping, giving body and a soft, creamy crust when baked.
- Butter or dripping
- Adds fat for richness and smooth texture in the mashed potato topping.
- Milk
- Adds moisture, keeping the potatoes and fish soft as they bake.
The step that matters
Mash the potatoes well. Thorough mashing gives a smooth topping without lumps. Overworking cooked potato releases starch and can make it gluey, so mash just until smooth.
Swap the potato
How well each one fits the dish's main ingredients (fish, milk, butter, pepper):
- Potatothe original
- Capsicumfits about as well
- Tomatofits less well
- Asparagusfits less well
Fit is the average pairing score against fish, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
