Activate the Yeast: In a small bowl, combine the warm water and yeast. Let it sit for 5-10 minutes until frothy.
Prepare the Dough: In a large mixing bowl, combine the lukewarm milk and sugar. Add the activated yeast mixture and stir. Gradually add the flour and salt, mixing until a dough forms. Knead the dough on a floured surface until smooth. Wrap it in plastic wrap and refrigerate for 1 hour.
Incorporate the Butter: Roll out the chilled dough on a floured surface into a rectangle. Place the cold butter between sheets of parchment paper and roll it out to the size of the dough. Place the butter layer on one-half of the dough, then fold the other half over the butter. Roll and fold the dough three times, chilling between each fold. Refrigerate for 1 hour.
Repeat the Folding: Roll and fold the dough three more times, chilling between each fold. After the final fold, refrigerate the dough for at least 4 hours or overnight.
Shape the Croissants: Roll out the dough to a rectangle and cut it into triangles. Place a slice of ham and a sprinkle of cheese on each triangle. Roll them from the wider end and curve the edges to form a crescent shape.
Proofing: Place the shaped croissants on a baking sheet lined with parchment paper. Let them proof in a warm place for 1-2 hours, or until doubled in size.
Preheat and Egg Wash: Preheat your oven to 400°F (200°C). Brush the croissants with the beaten egg mixed with water.
Bake to Perfection: Bake the croissants for 15-20 minutes or until golden brown and flaky. Rotate the baking sheet halfway through for even baking.
Cool and Enjoy: Allow the ham and cheese croissants to cool on a wire rack for a few minutes before indulging in the irresistible layers of buttery goodness.
Conclusion:

Congratulations! You’ve successfully created a batch of homemade ham and cheese croissants that rival those from your favorite bakery. Share these delectable treats with friends and family, and bask in the satisfaction of mastering the art of French pastry.
