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

What each ingredient does

All-purpose flour
Provides the structure that holds the wafer together as it bakes.
Unsalted butter
Adds richness and tenderness, and helps the dough bind.
Powdered sugar
Sweetens the wafers and dissolves smoothly into the dough.
Eggs
Bind the dough and add structure and richness as they set.
Lemon rinds and juice
Provide the bright lemon aroma and a tangy acidity.

The step that matters

Cooking the wafers over the fire. The tongs must be hot and the paste thin enough to bake quickly. Turning them often keeps both sides evenly golden instead of scorched or pale.

Swap the lemon
