I make croissants myself from puff pastry. The link to the recipe ladies in the end.
You can certainly use the finished dough or just take the finished croissants, then the cooking process will be instant!And so, a croissant cut in half lengthwise and dry on the grill in the oven at 180-200* 2-3 mins until it will turn brown.
Apple cut into small slices.
Melt the butter in a pan, add the apples and simmer for 5 minutes until soft.
Then add sugar (I took brown), cinnamon, vanillin. Caramelize apples for another 3 minutes. Caramel should be formed and cover the pieces of apples.
The lower half of the croissant smear with a spoon of sour cream (you can take whipped cream)
Of sour cream put apples and cover the top of the croissant. Pour caramel from the pan. I have all the caramel coated apples and it is not there because of sugar I add less.
Well, a hearty Breakfast or dessert is ready! Very tasty!
