Use a graduated pipet for smaller volumes. When finished, triple the volume of solution in the 1 L beaker with water and pour down the drain. If an aqueous solution is 24% or less ethanol it poses no environmental threat and can be poured down the drain.
1 Freeze breadsticks, uncovered, until completely firm, at least 2 hours.  FRY: Pour oil to a 2-inch depth in a large heavy-bottomed pot. Heat oil until it reaches a temperature of 350Â°F. A few at a time, fry the mozzarella sticks, being careful not to overburden the oil and cause the temperature to plummet. When done, cheese-sticks will be crispy and browned on the exterior, about 5 minutes. Drain on a double stack of paper towels.
Pin it. Compounding the dangerousness of homemade mozzarella is the fact that it comes together in about twenty minutes. You warm the milk with some citric acid (not as scary as it sounds), add the rennet to separate the milk into curds and whey, heat it again, knead stretch knead, and then you have mozzarella.
