Argentine Medialunas (Butter Croissants)

Medialunas de manteca doradas y brillantes con almíbar junto a un café con leche
Rate this recipe

Medialunas (“half moons”) are the breakfast and afternoon snack of Argentina and Uruguay, always with a café con leche. They’re cousins of the French croissant, but smaller, softer, sweeter, and glazed with a shiny sugar syrup. Making them at home takes chilling and rising time, but the actual work is modest and the result is worth it.

  • Makes: 20 medialunas
  • Prep time: 1 hour
  • Chilling and rising: 2 hours 30 minutes
  • Bake time: 18 minutes
  • Total time: 3 hours 50 minutes

Ingredients

For the dough

  • 4 cups (500 g) all-purpose flour
  • 2 1/4 teaspoons (1 packet, 7 g) active dry yeast
  • 6 1/2 tablespoons (80 g) sugar
  • 1 egg
  • Scant 1 cup (220 ml) warm milk
  • 3 1/2 tablespoons (50 g) softened butter
  • 1 teaspoon lemon zest
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt

For laminating, glazing and syrup

  • 14 tablespoons (200 g) cold butter
  • 1 beaten egg, for brushing
  • 1/2 cup (100 g) sugar and 1/2 cup (100 ml) water, for the syrup

Instructions

  1. Make the dough. Dissolve the yeast in the warm milk with 1 tablespoon of the sugar and let stand 10 minutes until foamy. In a bowl, mix the flour, remaining sugar, salt and zest. Add the yeast mixture, egg, vanilla and soft butter. Knead 8 minutes until smooth. Wrap and refrigerate 30 minutes.
  2. Prepare the butter block. Place the cold butter between two sheets of parchment and pound it with a rolling pin into a 1/2-inch-thick square. It should be cold but pliable.
  3. Enclose the butter. Roll the dough into a rectangle twice the size of the butter square. Place the butter in the center and fold the dough over it, sealing the edges.
  4. Make 3 folds. Roll into a long rectangle and fold in thirds like a letter. Turn 90 degrees and repeat. Chill 20 minutes. Do a third fold and chill 20 minutes more.
  5. Shape. Roll the dough 1/4 inch thick into a rectangle about 10 inches wide. Cut into triangles with a 4-inch base. Make a small slit in the center of each base, roll up toward the tip, and curve the ends into a crescent.
  6. Let rise. Place on buttered baking sheets, spaced apart, and let rise in a warm spot for 1 to 1 1/2 hours, until doubled.
  7. Bake. Preheat the oven to 400°F (200°C). Brush with beaten egg and bake 15 to 18 minutes, until deep golden.
  8. Glaze. Meanwhile, boil the sugar and water for 3 minutes. Brush the hot syrup over the medialunas as soon as they come out of the oven.

Tips

  • Keep everything cold: if the butter starts leaking while rolling, chill the dough 15 minutes. That’s the secret to flaky layers.
  • For breakfast: shape them the night before, cover and refrigerate. In the morning, let them rise 1 hour at room temperature and bake.
  • Filled medialunas: add a strip of ham and cheese, or a teaspoon of dulce de leche, at the base before rolling.
