Why it works: Potato and soy milk share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and 34 recipes mention both. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, soy (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the batter
Beat all ingredients together or mix by hand.
Let the batter sit for 15–30 minutes; it should be slightly stiffer than cake batter.
Fry and finish
Fry 1/4 cup or smaller spoonfuls of batter in hot oil, a few at a time, until they are golden brown.
Check doneness by breaking open a donut; rice flour products are unpleasant if undercooked and dry if overcooked.
Drain donuts well.
Roll donuts in powdered sugar or cinnamon sugar, or dip them in vanilla or chocolate powdered sugar glaze.
Serve
The recipe makes a large batch, freezes well, and provides a ready snack for someone hungry for a good donut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Adds moisture and a tender, soft crumb to the donut.
- Rice flour
- Forms the main structure of the donut, and is the base of the batter.
- Cornstarch
- Lightens the texture and softens the crumb, since it contains no gluten.
- Eggs
- Bind the batter and add structure as they set during frying.
- Baking powder
- Releases gas during frying, helping the donuts rise and become light.
- Milk
- Adds moisture and richness, helping the batter hold together.
The step that matters
Check doneness by breaking open a donut. Rice flour donuts turn unpleasant when undercooked and dry when overcooked, so the interior must be checked, not just the golden colour. Frying until golden without testing the centre can leave the batter raw inside.

- Turmericabout as good a flavor fit
Fit is the average pairing score against potato, rice, flour, soy milk, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
