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.
Stuff each mushroom with a quarter of the mixture. Bake in the oven for about 35 to 40 minutes. Now, top each with about 1 tablespoon of the mozzarella and continue baking for another 10 to 12 minutes, or until the cheese is just beginning to get golden on top.
