To make starter to use for recipe:
Scoop 1 cup of Sun Flour Mills dry pizza crust/French bread mix right from the package into a large mason jar or tupperware container. Add 1 cup warm water and whisk together
Optional: at this point you can add 1 tsp of dry active yeast if you are not yeast intolerant
Dough will be on the counter at room temperature for a total of 7 days
The starter needs some oxygen, so make a few small holes in top of mason jar lid, or leave some space at the top of the tupperware (use a container large enough to allow for at least 1 in of space from the dough to the lid)
Let rest for 24 hours
For the next 6 days (everyday) add 1/3 cup of the pizza crust/french bread mix and 1/3 cup of warm water to the starter. The starter will be ready on day 7
You will now have 3 cups of sourdough starter. Keep this in the fridge. Now that your starter is developed, you only need to feed it once every few weeks or when going to make a loaf of bread.
When you make the loaf of sourdough bread, you only need 2 cups of the dry mix. The additional left over cup is the cup you should then feed your starter with.
When you feed your starter remember you must add equal parts of the mix to warm water. This will ensure that you will end up with perfect bread
If you just add the mix or the water without measuring equal amounts, the bread will not turn out like it should
