Wash the outside of the lemon, being sure to remove any dirt. Slice the lemon, pick out the seeds. Using a food scale, weigh the lemon slices until you get 4 oz. Place the lemon in a food processor. Process until smooth.

Add eggs, vanilla, salt and sugar to the food processor. Blend on high about 20 seconds. Lower the speed and slowly pour in the melted butter through the feed tube. Process until smooth.

Press one crust into 9” pie plate. Pour the lemon mixture in. If desired cut out shapes from second crust and arrange evenly on top.
