In the stand mixer bowl add the water and sprinkle the yeast on top, let sit 10 minutes then stir to combine. Add the olive oil and flour start to knead then add the salt. Knead 7 - 8 minutes until compact and the dough pulls away from the sides of the bowl.
Remove the dough and form into a ball, place in a lightly oiled bowl cover and refrigerate 10-12 hours.
Remove the dough from the bowl and place on a lightly floured flat surface, divide the dough into 4 parts, and form into balls. Place on a parchment paper lined baking sheet, cover with a clean tea towel and let rise 1 hour or until doubled in bulk in a warm draft free area.
Pre-heat oven to 425F/220C.
Bake for 15-20 minutes or until golden brown and baked through. To help give the buns a crunchier crust, spray the buns with water and the oven before baking, (bread is baked with an internal temperature of 190F/88C). Immediately move to wire rack to cool completely. Enjoy!
Notes
If the dough is too dry then add a bit more water, too wet add a bit more flour.While these buns are so easy, they are more delicious with a long cold rise. If you need something quicker, you can let them rise in a warm draft free area for a couple of hours and then continue with the recipe.Cool completely then seal in an airtight bag. If these are stored away from direct sunlight and stay well-wrapped they should last several days at room temperature.For longer storage, wrap individually and freeze in an airtight container or bag. Store frozen for up to three months and thaw as needed.
