Big pitchers of lemonade may sound a bit "past it" to the younger generation these days, but it beats most things on hot summer days. Give it try, it's easy and this one recipe will give you about 4 liters (4 quarts) of lemonade super cheap. It only needs to be served cold with ice. It's not too bad with a little vodka in it!!!!!!It's good if you use water, sparkling water or half and half for just a little fizz.The amount of lemon juice in a lemon up here in the north it would seem can vary greatly, which will affect the syrups lemon flavor. So you may have to adjust the lemon juice to amount of syrup.I think that lemonade should be very lemony. So make a glass for yourself and taste it. If it tastes more sweet than lemony add more strained lemon juice to the syrup until to get it the way you want.
