Egg wash (1 egg beaten with 1 tablespoon of water)
Instructions
Step1 : Prepare the doughMix together milk, yeast, and sugar in a small bowl and let it ferment for 5-10 minutes until frothy; this means that the yeast is active. Mix the flour with salt in a large mixing bowl, then add to that the yeast mixture. Let the dough rest for about 5-7 minutes until it becomes smooth, then cover it with a damp cloth. Dough Rising 1-2 hours or until it doubles in size.
Step2 : grease the dough with butterOnce the dough has risen, squeeze the dough, then roll it out to the rectangle shape. Take the chilled butter and place it in the middle of the dough. Fold the dough over the butter in an envelope fold, then roll it out again. You will be folding and rolling the dough at least three times, chilling it for approximately 20 minutes each time before rolling out the dough again; this is what keeps the butter firm and what allows the layers to form in your croissants.
Step3 : shape and fill the croissantCut into triangles; put a slice of ham and cheese on the wide end and roll it together tightly toward the narrow, crescent shaped; place each croissant in a parchment-lined baking sheet so it can't unroll.
Step4 : Let the croissant riseCover the croissants with a towel and let it rest for 30-45 minutes until they puff up a little bit.
Step5 : Bake the croissantPreheat your oven to 400°F (200°C). Brush each croissant with egg batter in order to give it a golden color, and bake it for 15-20 minutes or until they are golden brown and crispy.
