How to Serve Frozen Key Lime Pie
Frozen Key Lime Pie is best served straight from the freezer, but make sure to let it sit for a few minutes at room temperature before slicing. This makes the pie easier to cut, ensuring clean slices. You can serve it on its own, or garnish it with fresh lime slices, mint leaves, or a dollop of whipped cream for extra decoration. For an elegant touch, serve it on individual plates with a sprinkle of zest or berries on top.
