Graham Cracker Crust
  1. Put graham crackers into a food processor until you have crumbs.
  2. Melt butter in microwave for 30 seconds in glass dish.

  4. Bake for 10 minutes at 350 degrees.
Almond Crust

  1. Wash limes. Rinse. Zest to get 1 tablespoon of lime zest.
  2. Juice limes to get ½ cup lime juice plus 2 tablespoons.
  3. Beat egg yolks with mixer until golden and creamy.
  4. Add in lime juice, sweetened condensed milk and lime zest.
  5. Mix until well incorporated.

  8. Bake at 350 degrees F for 10-15 minutes. Center should not jiggle.
  9. Cool completely. Refrigerate overnight.
  10. Apply Whipped topping before serving. If you stabilize whipped cream, you can apply whipped cream and put back into refrigerator for several hours to two days.
Whipped Cream
  1. Mix cream, cream cheese, confectioner's sugar, vanilla together for five minutes until stiff.
Notes
Lime Juice: You will want ½ cup plus two tablespoons. Key limes give very little juice, so you'll need 25 or more. I mixed key limes with Persian limes, which are much juicier.

Almond Crust: Some recipes call for adding an egg. I did not do that for this type of pie.
