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.
1 In a large heavy saucepan, heat the oil to 365 degrees F (185 degrees C).  One at a time, coat each mozzarella stick in the flour mixture, then the egg mixture, then in the bread crumbs and finally into the oil. Fry until golden brown, about 30 seconds. Remove from heat and drain on paper towels.
