These are pre-measured – add only sugar and water. Convenient pouches take all the guesswork from making syrup. Just open a pouch – add 5 lbs. sugar and enough water to make a gallon – that’s all there is to it. EE-ZEE concentrates are packed 10 pouches per carton, and 10 cartons per master case. A carton makes 10 gallons of syrup – enough for about 1250 Snow Kones.
