Why it works: Sweet potato and flour work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweet Potatoes
Ingredients
Directions
Prepare
Boil the sweet potatoes until almost tender, then remove the skins.
Make and coat
In a bowl, make a batter with a little milk, the beaten egg, flour, and season with pepper and coarse sea salt.
Cut the potatoes into thick slices and dip them in the batter.
Fry
Brown the battered slices on both sides in hot beef drippings.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the main body of the fritter, becoming soft and creamy when cooked through.
- Flour
- Mixes with the egg and milk to form a batter that coats the slices and crisps when fried.
- Beaten egg
- Binds the batter so it clings to the potato slices during frying.
- Beef drippings
- Conducts heat to brown the batter and adds savoury flavour to the fritters.
The step that matters
Brown the battered slices in hot drippings. The fat must be hot enough to set and brown the batter quickly. If it is too cool, the coating absorbs fat, turns greasy and may slide off before it crisps.
Swap the sweet potato
How well each one fits the dish's main ingredients (milk, egg, flour, pepper, beef):

Fit is the average pairing score against milk, egg, flour, pepper, beef. Candidates are from the same food group and used in at least 100 recipes.
