this recipe got me to thinking,"powdered sugar in lemonade?" so i had to try it. what a disappointment. the sugar did not dissolve or sweeten the lemonade. also, only 3 cups water to the juice of 7 large lemons is not right. to salvage the lemonade i added enough water to make 3 quarts, strained out the chopped mint and undissolved powdered sugar, and added a half cup granulated sugar and 1/8 cup marrionberry syrup that i had on hand. finally a drinkable lemonade. the only part of this recipe that i did like was the mint, but next time i make lemonade i will run the mint through the juicer with the lemons to eliminate the step of straining out the mint leaves.
