Ingredients

  • 4 to 5 egg yolks, beaten
  • 1 can sweetened condensed milk
  • 1/2 cup Key lime juice or 3/4 cup regular lime juice
  • 2 large spoonfuls Cool Whip

Instructions

  1. To beaten egg yolks, add sweetened condensed milk, lime juice, and Cool Whip.
  2. Blend well until smooth.
  3. Pour the mixture into a prepared pie shell.
  4. Chill in the refrigerator for 2 to 3 hours.
  5. Garnish with additional Cool Whip if desired.

Tips & Substitutions

For a richer flavor, consider using fresh Key lime juice instead of regular lime juice. If you're short on time, you can substitute the Cool Whip with a store-bought whipped topping. To prevent the pie from becoming too sweet, adjust the sweetness by adding a pinch of salt. Make sure to mix the ingredients until fully combined for the best texture.

Serving Suggestions

Serve the pie chilled, topped with additional Cool Whip for a delightful presentation. It pairs wonderfully with fresh berries or a scoop of vanilla ice cream for a refreshing treat. This dessert is perfect for summer gatherings, offering a zesty contrast to heavier dishes like Turkey Shepherd's Pie(Weight Watchers).

Storage & Reheating

Store any leftover pie in an airtight container in the refrigerator for up to 3 days. If you prefer a firmer texture, you can place it in the freezer for a short time but be aware that this may alter the creaminess. To serve, let it thaw in the fridge for a few hours before enjoying.

Frequently Asked Questions

Can I use regular lime juice instead of Key lime juice?

Yes, you can substitute regular lime juice for Key lime juice. However, keep in mind that the flavor will be slightly different, as Key limes have a more intense and tart profile. If using regular limes, you may want to adjust the sweetness accordingly to balance the flavors.

How do I know when the pie is set?

The pie will be set after chilling in the refrigerator for at least 2 to 3 hours. You can check its firmness by gently shaking the pie; it should be firm but slightly jiggly in the center. If it appears too liquid, allow it to chill longer until it reaches the desired consistency.

Can I make this pie ahead of time?

Absolutely! This pie can be made a day in advance, making it a great option for gatherings. Just be sure to keep it covered in the refrigerator. If you’re planning to serve it later, wait to add any additional toppings like Cool Whip until just before serving for the best texture.
