Why it works: Vanilla and banana match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 1,430 recipes mention both. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the dough
Sift flour then measure and resift 3 times with baking powder, soda, salt and nutmeg.
Cream shortening then blend in sugar.
Add vanilla and eggs and beat until light and fluffy.
Add combined bananas and buttermilk and stir until well mixed.
Add flour mixture in 4 portions stirring thoroughly after each addition.
Chill before rolling.
Shape and fry
Remove ¼ of dough from refrigerator at a time then knead lightly 4 or 5 times and roll to ⅜ inch thickness and cut with floured 2½ inch doughnut cutter.
Fry in deep oil heated to 375°F until golden brown then lift out and drain on absorbent paper.

Sugar and vanilla share little aroma chemistry, yet 35,031 recipes mention both: they likely 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
- All-purpose flour
- Forms the main structure of the dough once its gluten develops.
- Baking powder
- Releases gas in the dough so the donuts rise and become light.
- Eggs
- Add structure and richness, and help the dough hold its shape while frying.
- Shortening
- Adds fat that tenderizes the dough and gives a softer crumb.
- Mashed bananas
- Add moisture and banana flavor, keeping the donuts tender.
- Buttermilk
- Adds moisture and acidity that works with the soda to help the dough rise.
The step that matters
Frying at 375°F until golden brown. Oil that is too cool lets donuts absorb grease and turn heavy, while oil that is too hot browns the outside before the centre cooks through. Holding the oil near 375°F gives a crisp, evenly cooked donut.
Flavor stand-ins for the nutmeg
How well each one fits the dish's main ingredients (flour, sugar, vanilla, egg, banana, buttermilk):
- Cinnamonbetter flavor fit
- Nutmegthe original
Fit is the average pairing score against flour, sugar, vanilla, egg, banana, buttermilk. 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).
