This recipe, originally from Chef Diane Unger, is unique in that contains no raw eggs, which used to be a standard ingredient for the pie. Since raw eggs are now a "no-no'" here's a tested way to produce a lime pie as bright and custard-like as the original, without using eggs. Garnish with a thinly sliced fresh lime "wheel" and wait for your guests to be "wowed." A great ending for a meal year around, but particularly during the warm summer months. Note: Do not be tempted to use bottled lime juice, which lacks depth of flavor. Also, use the larger Persian Limes...not the true Key Limes. It would take about 40 of the little Key Limes to yield a cup of juice!
