I make croissants from puff pastry myself. The link to the recipe will be given at the end.
Of course, you can use ready-made dough or just take ready-made croissants, then the cooking process will be instant!
And so, cut the croissant in half lengthwise and dry it on the grill in the oven at 180-200 * 2-3 minutes, until it is browned.
