Combine the flour and salt in the bowl of a stand mixer fitted with a dough hook attachment. Stir to combine.
Heat water in microwavable safe bowl for 30 seconds. Temperature should be between 85F and 95F. Add yeast to water and let sit for 5 minutes. We're not looking for a full activation, just a bit of a jumpstart.
Slowly add water/yeast mixture to the stand mixer, mixing on low until it forms a smooth consistency, about 10 minutes. Note: dough will be very wet and sticky, and the bottom will stick to the bowl.
With the dough still in mixer bowl, fold into a ball, cover with plastic wrap, and set on counter for 1 - 2 hours to kick-start fermentation. You should notice some rise in the dough but not doubling in volume.
Place in refrigerator for 1 to 2 days.
