Create a double boiler using two kitchen pots and add three liters of milk. Heat it slowly to 30 celsius. This will happen pretty quickly so stay with it.
Cooking Note: If it gets to hot DON'T PANIC if it hasn't curdled just let it cook down by putting the pot in some cool water. You haven't ruined it. Just stay calm and cook it down.
While this is heating, dissolve rennet in 3 tablespoons of water and the calcium chloride in another 3 tablespoons of water.
After that cut the curd into squares with a knife and stir. Then let it sit for another 20 minutes.
