I didn't believe this would be good either until I tried it. It's good for calorie counters who don't want to sacrifice flavor. The sour creams blends well with the sugar, making the whole thing taste like strawberries with whipped cream.
Gazpacho is like chili, where everyone has a certain way of doing it and it will taste different every time. I got this recipe from my college Spanish book, and have been using it for years. Good for hot days or as a drinkable snack.
