- Cool Whip - or sweetened whipping cream
- Graham cracker crust - use a pre-made crust or make your own
No need to squeeze limes for this pie. Using lime juice makes this recipe much easier to make. Of course, if you want to squeeze fresh limes you can do that as well. When selecting lime juice, if you want a more authentic flavor make sure to look for a bottle that is specifically labeled key lime juice. Key limes are more acidic than the larger limes you often see at the grocery store, which makes them both tarter and more aromatic.
While the limes provide the tart flavor, the sweetened condensed milk is the balance of the sweet. Sweetened condensed milk is a milk that has been heated to remove any water, reducing the milk and thickening the consistency. It also has sugar added to it. When added to a no-bake pie it helps to create a creamy and smooth consistency.
Once your pie is finished you can decorate it with extra whipped topping, lime zest, sliced limes, or graham cracker crumbs. Keep the garnishes simple to let the key lime flavor really shine.
