Pecan Kisses

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. Add a pinch of salt to the egg whites and beat until stiff.

  2. Add the cream of tartar and sugar, and continue to beat until very stiff.

  3. Blend the flour with the chopped pecans, then stir this mixture into the egg mixture along with the almond extract.

Bake

  1. Drop spoonfuls onto greased parchment paper and bake for about 25 minutes.

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

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the cookies their light, airy structure.
Granulated sugar
Stabilizes the whipped whites and adds sweetness and a crisp, dry exterior.
Cream of tartar
Acidifies the egg whites, stabilizing the foam so it holds its volume longer.
Chopped pecans
Add texture and nutty flavor, and body to the batter.
Flour
Lightly binds the pecans into the batter so they stay distributed through the cookies.

The step that matters

Beating the egg whites to very stiff. Under-beaten whites will not hold enough air, so the cookies spread and turn dense. Over-beaten whites turn dry and grainy and lose their structure. Beat until the peaks are firm and glossy, and fold the flour and pecans in gently to keep that air.

Swap the pecans

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

  1. Pistachiofits better
  2. Cashew nutfits better
  3. Hazelnutfits better
  4. Pecansthe original

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