+To make the magic paste:
°250 grams of flour
°75 ml high quality olive oil
°1 sachet of dried baker's yeast (or 1 sachet of briochen yeast)
°1 egg, beaten in an omelette (1/2 for browning .)
°0.5 for dough)
°1 tbsp. coffee sugar
°1 tbsp. coffee salt
°75ml lukewarm water (or 100ml if using dried yeast)
To decorate:
°8 slices cheddar
°2 leeks
°1 onion
°400 gm minced beef
°butter for cooking
°2 tbsp. tablespoon tomato coulis
°1 egg yolk to brown

* Preparation steps

To garnish: saute chopped leeks and onions over low heat until golden brown.
Add the meat and tomato cole, fry for a few minutes and put in a colander.
Leave it for 10 to 15 minutes in a colander and let it cool while you prepare the dough.
To prepare the magic dough: With dried yeast, mix baking powder, sugar, 50 grams of flour and 50 ml of lukewarm water.
Cover with a clean cloth and leave for 15 to 30 minutes (it should double in size).
With brioche yeast, go straight to the next step (but be careful, only about 75ml of water is used): In the bowl of a food processor, mix flour, salt, sugar and powdered milk.
Dig a well and put in 1/2 a beaten egg, oil and sourdough (or briochen yeast).
Run the food processor on the hook on medium speed for 15 minutes, gradually adding lukewarm water. You should get a smooth, not sticky dough.
Cover the dough with a clean cloth and leave it at room temperature for at least an hour (it should double in size).
Dust the work surface with flour and roll out the dough with a dough roller in the form of a large rectangle (it is better to have a silicone mat that will put in the oven, otherwise put a baking sheet under the dough).
Draw without cutting the dough into three equal rectangles.
Cut strips on the two outer strips (with a pizza wheel).
Line the center with the cheese pieces, then add the filling.
Cover with the rest of the cheese.
Close the braid by alternately folding each strand (one on the right, one on the left).
Solder the ends and let the dough rise for 30 to 60 minutes at room temperature.
Heat oven to 180 ° C.
Fry the braid with the rest of the beaten eggs and bake for 25 minutes.
Serve hot.

Enjoy !
