Put the flour, the sugar and yeast in a bowl, whisk to combine, add and salt whisk again. Pour the liquids mixture into the bowl.
Use large spoon (or pastry scraper) to mix everything together, and knead briefly to bring all the ingredients together.
Take the dough out of the bowl and knead, you will see the dough will be elastic after about 2 minutes.
Add the butter and knead by using the heel of your hands to compress and push the dough away from you, then fold it back over itself. Give the dough a little turn and repeat. Put the weight of your body into the motion and get into a rhythm. Keep folding over and compressing the dough. Knead for 10-15 minutes (up to your strength and up to the recipe) or until the dough is soft, pliable, smooth and slightly shiny, almost satiny.
Or you can also try stretching part of the dough, if it can stretch into a thin sheet without breaking, you've kneaded enough.
Or you can try by touching the dough and count to 10, if there is nothing stick to you hand, the dough is ready to rise.
