In a medium bowl, mix together the almond flour, brown sugar, and salt. Mix well. Pour in the melted butter and stir until well blended.
Place the crust mixture into a 9-inch greased pie dish. Press and tamp the crust into the bottom and up the sides of the pie dish using a small smooth-bottomed cup.
Bake for 8 minutes or until lightly browned. Remove from the oven and cool completely.
Filling
Preheat the oven to 350°F.
Using a food processor or blender, blend the eggs until smooth. This step is necessary so that the filling ends up very creamy and smooth.
In a mixing bowl, pour in the condensed milk, lime juice, and eggs. Using a whisk or mixer, beat the mixture until well blended. Be careful not to overblend.
Pour the mixture into the cooled crust. Place a pie ring or aluminum foil ring around the crust to keep it from over-browning.
Bake for 20 minutes until set and only slightly jiggly in the middle. If necessary, cook for 5 minutes more. Cool and then place the pie in the refrigerator for about 4 hours. Serve chilled. Garnish with whipped cream or lime slices.
Notes
Substitution
You can make this crust with graham cracker crumbs. Substitute 1¼ cups of crushed graham cracker crumbs for the almond flour.
Cooling Pie
If in a hurry, cool the cooked crust for a few minutes and then place it on a potholder in the freezer for 10 or 15 minutes.
