Mix yeast with warm water and 4 g sugar, cover with a wet cloth and let sit for 10 minutes.
Add flour, salt, and sugar with the yeast mixture, knead. Cover with a wet cloth and let sit for 20 minutes.
Add oil to the dough and knead. Cover with a wet cloth and let sit for 2 hours.
Over medium heat, fry the garlic in the butter until golden. Let it cool.
Divide dough into 4 pieces. For each piece, roll out the dough to the size of the pan.
Place one piece of the dough on the pan, brush with a layer of the butter/garlic mixture.
Repeat step 6 twice, then add the last piece of dough on top.
Place a 3 inch diameter bowl (or something circular) in the middle. Using a knife, as if slicing a pizza, cut the dough into 16 slivers (but do not cut all the way to the middle, stop at the edge of the bowl).
Twist two of the slivers together.
Repeat step 9 until you end up with a total of 8 twists.
Remove the bowl.
Cover with a wet cloth and let sit for 1 hour.
Mix the egg yolk and water to make an egg wash. Brush the top of the bread with the egg wash.
