Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potato
- Forms the bulk of the dish and provides starch and moisture for a soft, tender texture.
- Eggs
- Set when baked, giving the mash structure and a light, custard-like body.
- Butter
- Adds fat and richness, carrying flavour and helping the top brown lightly.
- Milk
- Adds moisture and softness, loosening the mash so it stays smooth when baked.
The step that matters
Baking in a water bath. Baking the dish in a pan of water keeps the outer edges from overheating. Gentle, even heat lets the egg set smoothly without curdling or drying out.
Swap the onion
How well each one fits the dish's main ingredients (sweet potato, butter, egg, cinnamon, milk, pepper):
- Capsicumfits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against sweet potato, butter, egg, cinnamon, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
