Its real easy to make MS and all you need to do is catch some wild yeast and feed them up to make a starter....then just feed your pet weekly and use it to make breads and rolls...I made fresh hamburgers and buns last night, was really easy...
Use the 123 method
1 is the starter ....say 100 grams
2 is the moisture .....say 200 grams
3 is the flour say 300 grams
then use salt 1.5 to 2% of the #1 weight so say 2 grams
mix all that and make the dough and cook it.....if you want to know how to do that I will PM you the recipes and my methods...takes me about 20 minutes to make plus 40 or so to cook.
