Ingredients

Directions

  1. Melt the butter and let it settle, then decant it.

  2. Pour 1 tablespoon of melted butter into a pancake pan and warm it.

  3. Add 2 tablespoons of flour paste to the pan and spread it evenly.

  4. Once the paste firms up, turn the pan to release the crepe.

  5. Toss the crepe to flip it, then transfer it to a warm dish.

  6. Sift powdered sugar over the crepe and repeat with remaining batter.

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

What each ingredient does

Butter
Adds fat and flavour, and greases the pan so the crepe releases and browns lightly.
Flour
Forms the batter paste that sets into the thin body of the crepe.

The step that matters

Turn the pan to release the crepe. Flip only once the paste has firmed up. If it is still wet, it tears or sticks, because the flour has not yet set into a sheet that lifts free from the pan.
