The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Bind the dough and add richness and structure as it sets in the fryer.
Baking soda
Reacts with the acidic cream of tartar to release gas, helping the doughnuts rise.
Cream of tartar
Provides acidity that activates the baking soda for lift and a tender crumb.
Shortening
Adds fat that tenderises the dough and carries flavour.
Milk
Adds moisture that hydrates the flour and helps form a soft dough.

The step that matters

Fry in hot oil until golden brown, turning often. If the oil is too cool, doughnuts absorb excess oil and turn greasy; if too hot, the outside browns before the centre cooks. Turning often gives even colour and cooking.

Swap the cinnamon

How well each one fits the dish's main ingredients (sugar, egg, milk, cream, flour):

  1. Nutmegfits about as well
  2. Cinnamonthe original
  3. Jalapenofits less well
  4. Turmericfits less well

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