Key Lime Icebox Cheesecake
No-bake cheesecakes-which use gelatin to set them firm-can be a dubious affair. We set out to create an icebox cheesecake with a supple, creamy texture-and great flavor too.
Why This Recipe Works
We wanted our Key Lime Icebox Cheesecake recipe to have a supple, creamy texture—and great flavor too. We tried all manner of recipes, including those that relied on the stiffening power of Cool Whip, and found it was best to stick to the tried-and-true combination of heavy cream and cream cheese thickened with gelatin. Allowing the gelatin to hydrate in a portion of the cream, then bringing it to a boil in the microwave fully activated its thickening power. We whipped the heavy cream and cream cheese smooth before adding the cream and gelatin mixture to ensure the most thorough dispersal of the gelatin. Lime juice and lime zest added just enough spark to perk up the flavor of the tangy cream cheese, while a moderate amount of sugar kept the filling light. Our crumb crust utilized an unusual ingredient—we combined crushed animal crackers with a little butter to bind them, then used a measuring cup or flat-bottomed glass to pack the crumbs into the springform pan.
