My Mom first made this, one night, about 25 years ago, to take to work the next day, for a potluck. She gave me the spoon to lick when she was done. That Strawberry Desert (our name for it) didn't make it to the potluck! But as she made the second one, she realized she hadn't done it right. She had mixed everything together then spread it one the pretzel crust! Oops! There wasn't anything she could do to fix it, so she added to it.. crushed pretzels sprinkled on top. Beautiful! But there wasn't room left to put it in the refrigerator, so in the freezer it went. That is the all time, greatest tasting, cooking mistake she ever made, and there were many! It's still my favorite. This variation is especially great in summer and anyone who tries it will keep asking for more.
