Directions

Make the sponge

  1. In a kettle, combine glucose, Canadian maple sugar, yellow sugar, and water.

  2. Cook the mixture until it reaches 256°F (125°C).

  3. Pour the hot mixture over the well-beaten egg whites and mix thoroughly.

  4. Add baking soda and stir until the mixture thickens.

Set and finish

  1. Pour into a paper-lined box and let it cool.

  2. Once cool, break apart with a fork and sell in bulk.

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

What each ingredient does

Glucose
Keeps the sugar syrup from crystallizing, giving a smooth, stable candy base.
Egg whites
Trap air as they are beaten into the hot syrup, forming the light, airy structure.
Baking soda
Reacts with the hot sugar mixture to release gas, making the sponge rise and lighten.
Canadian maple sugar
Adds maple sweetness and flavor to the candy.

The step that matters

Adding baking soda. Baking soda must be stirred in quickly once the hot syrup is combined with the egg whites. It releases gas that expands the foam; if it sits too long, the mixture sets before it can rise, and the sponge turns dense.

Swap the pecans

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

  1. Pecansthe original
  2. Almondfits about as well
  3. Chestnutfits about as well
  4. Milletfits less well

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