Just saying the name of this recipe is likely to bring a smile to your face -- and inspire you to get into the kitchen. After all, strawberry gelatin (okay, Jello!) was a mainstay on many a family dinner table for weeknight dessert. Here, a flavored gelatin mix is your approved shortcut (and time travel) to nostalgic flavor, while condensed milk lends that trademark consistency. Fresh strawberries are a mandatory garnish.
