well have just sampled it with some lemonade I made up a few days ago - seems pretty perfect to me. Used 1/4 cup strawberry syrup (had about 1 extra cup of water in it, to help strain, but no extra water/ lemon juice), 1/4 cup of the lemonade recipe (double strength) and 1/2 cup water. very tasty. Hint of strawberry, might try increasing the strawberry content next time. Not overly sweet, might half the sugar in the lemonade, but that's all.
Off to make another batch for sunday night as reckon the kids would like some later!
Thanks JD!
