1/4 teaspoon salt
1 cup sugar
1 teaspoon vanilla extract
1 cup all-purpose flour
1/4 pound unsalted butter, melted and cooled
freshly grated lemon zest (optional)
Preheat oven to 375 F. Butter and flour the madeleine pans. If
using a non-stick pan, only use cooking spray. Beat the eggs,
salt, and sugar together until thick, 8 minutes. Add the vanilla.
Fold in the flour, rapidly, but gently. Fold in the butter gently.
Quickly spoon the mixture into the madeleine pans, about 3/4 full.
Bake until golden, about 8-10 minutes. Watch carefully. Remove
from pans, cool on racks. If desired, dust with powdered sugar
