Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Starchy base that gives the fritters their body and natural sweetness.
- Eggs
- Yolks enrich and bind the mash; frothed whites help the coating stick.
- Milk
- Adds moisture and softens the mash so it shapes smoothly.
- Butter
- Adds fat for richness and a softer, more tender interior.
- Sugar
- Adds sweetness and helps the exterior brown when fried.
- Cracker crumbs
- Form a crisp, golden coating around the cakes when fried.
The step that matters
Fry in deep, boiling fat until golden brown. The fat must be deep and very hot so the coating crisps quickly. Cool fat soaks into the cakes and makes them greasy, while fat that is too hot browns the outside before the centre heats through.
