In a bowl, mix flour and sugar. Add dry yeast on one side of the bowl and salt on the other. Combine hot water and milk together and slowly pour on the dry ingredients while mixing. Mix until all are well moistened. Lastly, add 3 tablespoons melted butter, and keep on mixing until the dough is formed. Dump dough in an unfloured surface and knead for several minutes until dough becomes soft and smooth around 5-7 minutes.

Form a ball and place on a greased bowl. Cover with a fling wrap or towel and place the bowl in a warm place to let the dough rise. After 30-40 minutes, depending on how warm it is, or when the dough has doubled in size, punch it down and dump it back to a slightly floured counter.

Form a log about 12 inches (30 cm) long. Using a knife or dough cutter, cut it into 16 equal pieces. Form each piece into a ball and then roll them one by one with a rolling pin making them flat and about 6 inch in diameter (15cm).

Once all are flattened, take the butter from the fridge and using a cheese grater, grate about a Tbsp of butter on top of one of the flattened dough. Make sure the butter is scattered on the surface of the dough then top it with another flattened dough and then the grated butter until all are in one pile and the last dough to cover the top.

Now, using the rolling pin, flatten out the pile by rolling from the center out until it is about half centimeter thin. It should look like a pizza crust and about 12 inches (30cm) in diameter. Using a dough cutter or knife, cut it into 12 equal parts as you would a pizza.

To form the croissants, gently stretch the dough on the sides of the wide end and then across going to the tip. do not pull too much. From the wide end fold and roll the dough towards the pointy end. Place formed croissants on a lined baking sheet making sure there are enough spaces in between. Cover the baking sheet with a kitchen towel and let the croissant proof for another 1-2 hours or until the dough has risen and is soft when touched.

Brush each croissant with egg wash and bake on a preheated oven at 400°F/200°C for 10 minutes and then lower temperature to 350°F/180°C and bake for another 7-10 minutes. Remove from oven and serve.
