Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the bulk and starchy body that makes up the mash.
- Butter
- Adds richness and fat, and helps the top brown in the oven.
- Sugar
- Adds sweetness that balances the earthy flavour of the potato.
The step that matters
Boil the potatoes until thoroughly cooked. Starch in the potato only becomes soft and smooth when fully cooked through. Undercooked potato stays firm and lumpy, so the mash will not blend evenly even with thorough mashing.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, sugar):
- Sweet potatothe original
- Leekfits about as well
- Potatofits about as well
- Capsicumfits less well
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
