* 3 tablespoons unsalted butter, melted
* ½ cup sugar, plus ¼ cup
* 8 large egg yolks

== Directions ==
# Spray a 9 by 5 by 3-inch metal loaf pan with nonstick spray.
# Line the pan with plastic wrap, allowing the excess to hang over the ends and sides.
# Combine the crushed amaretti cookies and the melted butter.
# Put in the lined pan and press down to firm and form a crust.
# Whisk ½ cup of the sugar, the egg yolks, lemon juice, lime juice, limoncello, and salt in a large metal bowl to blend.
# Set the bowl over a saucepan of simmering water (do not allow the bottom of the bowl to touch the water).
# Whisk the egg mixture until it is thick and creamy, and a thermometer inserted into the mixture registers 160°F, about 5 minutes.
# Set the bowl of custard into another bowl of ice water to cool completely.
# Stir in the zest.
# Using an electric mixer, beat the cream and remaining ¼ cup sugar in another large bowl until firm peaks form.
# Using a large rubber spatula, gently fold the whipped cream into the custard.
# Spoon the mixture onto the prepared crust.
# Fold the overhanging plastic wrap over the custard and freeze until frozen, at least 8 hours or up to 3 days.
# Unfold the plastic wrap.
# Invert the semifreddo onto a platter and peel off the plastic wrap.
# Cut the semifreddo into 1-inch slices and sprinkle with crushed amaretti cookies and serve.
