In a mixer bowl with a kneading hook put yeast flour sugar and water and mix until the dough is combined on medium speed.
Add salt and continue at the same speed.
Add the oil and transfer to a high speed until you get a dough with a smooth and slightly sticky texture.
Stop the mixing and let the dough rise inside the bowl for an hour and a half, cover with a lid or a kitchen towel.
Once the dough has doubled in size you should get about 900 grams of dough. Divide the dough into 3 pieces of about 300 grams each, or into 6 pieces of about 150 grams each depending on the desired braiding.
Knead each piece into a ball shape.
Roll each ball of dough into a strip about 40 cm long.
Tighten the edge strips to each other to braid, either from 6 strןps or from 3 strןps.
Shape the desired braid and leave to rise for about 30-40 minutes on a baking tray with baking paper and cover with a kitchen towel.
