I was hoping for a low calorie/low fat key lime pie using fat free sweetened condensed milk that I'd never used before. I am from Florida and have made key lime pie many times from key limes and from Persian limes successfully. The pie lacked that tangy and sweet flavor of a key lime pie. I think the yogurt and gelatin was too much and diluted the flavor, besides giving it a weird texture. The amount of crumbs would not cover the 9 inch pie plate no matter how I patted them. Key lime pie NEVER has meringue on it, even if it's lower in fat. It's better to use low fat sour cream mixed with confectioners sugar on top than that. I'll keep looking for another recipe or just make the real thing and eat it as a splurge once in a while.
