Why it works: Sweet potato and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 314 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Sweet Potato Balls for Frying
Ingredients
Directions
Prepare the filling
Boil the sweet potatoes until tender, then mash them.
In a saucepan, boil the milk with lemon peel, sugar, and salt.
Once the milk boils, remove it from heat and mix in the mashed potatoes to form a thick paste.
Allow the mixture to cool, then shape it into balls.
Coat and fry
Coat the balls with bread crumbs and egg yolks.
Fry the balls until they are golden brown.
Serve
Serve with sugar sprinkled on top.

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 holds the balls together.
- Milk
- Adds moisture and softness to the mashed potato paste.
- Egg yolks
- Bind the coating so bread crumbs stick and brown during frying.
- Bread crumbs
- Form a crisp, golden outer crust when fried.
- Sugar
- Adds sweetness that complements the sweet potato.
The step that matters
Cooling the paste before shaping. A warm, soft paste is sticky and hard to shape, and it can break apart or tear the coating. Letting it cool firms the starch so the balls hold their form through coating and frying.
