  2. Pour the brandy over the sugar.

  3. Light the sugar just before serving to enhance the flavor.

Sugar and brandy barely smell alike, yet cooks put them together in 11,939 recipes: they 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

Sugar
Melts and caramelizes under the flame, adding browned, bittersweet sweetness to the dish.
Brandy
Its alcohol vapor ignites to create the flame and adds aroma.
Grapefruit or orange
Serves as the hollow shell that holds the sugar and brandy while they burn.

The step that matters

Light the sugar just before serving. Brandy's alcohol vapor is what burns, so the flame needs enough alcohol above the sugar to catch. Lighting too early lets the alcohol burn off and the caramelized sugar cool and harden, so the flame and flavor fade before the dish reaches the table.

Swap the grapefruit

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

  1. Vanillafits better
  2. Apricotfits better
  3. Raisinfits better
  4. Grapefruitthe original

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