Easy Peasy Pizza cheese
4 gallons raw cow's milk
1 1/2 cups yogurt
3/4 cup buttermilk
1/8 tsp powdered calf rennet (or follow the directions for what ever rennet you have)
3/8 cup kosher salt
In a double boiler, warm milk to 90*F. Whisk yogurt with buttermilk and enough warmed milk to make it pourable, then whisk into kettle of milk.
Turn off heat and cover. Maintain temp while acidifying milk for 1 hour. Dissolve rennet in 1/4 cup cool water. Gently but thoroughly stir rennet into milk for about 20-30 seconds. Use skimmer to stop the motion of the milk. Check in about 45 minutes for clean break and, if achieved, cut curd into 3/4 inch cubes.
Let curds heal for ten minutes - allow to rest without stirring. Use a skimmer to gently lift curds and cut any that are large into smaller pieces. Turn heat to medium-low and allow to come to 105* F, about one hour. Occasionally stir gently if you wish, but I did not, as I did chores during this time.
Ladle curds into a cloth-lined colander. After draining for an hour or so, toss with salt and continue to drain overnight or 6- 8 hours. I then refrigerate for a day and then shred in a food processor and freeze but you can shape it how ever you want.
