Squeeze 5/8 to 3/4 cup of fresh key lime juice (from maybe 16 or so key limes).

Separate 4 eggs, keeping only the yolks for this recipe.

Mix the can of sweetened milk and egg yolks at low speed until well blended. Very slowly mix in the key lime juice, blending often.

Pour into 9 inch graham cracker crust. Bake at 350 degrees for 10-15 minutes until the pie "sets." (Which means it's firm like pudding is firm.)
