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.
In a non-stick skillet, over medium heat, scramble egg whites, seasoning with salt and pepper to taste. To serve, lay tortillas on a work surface. Fill each with approximately 2 oz. of mozzarella, then spoon in egg whites and potato/spinach mixture, dividing evenly between each tortilla. Roll burrito style, heat in microwave for 30 seconds each, or for a crispier outside, bake in 350 degrees F oven for 5 minutes and serve.
