Chill until icy cold: 1 cup evaporated milk
As milk chills, mix together in large bowl: 2 egg yolks (retain whites)
6 Tablespoons sugar
1/2 Tablespoon grated lemon rind
2 Tablespoons lemon juice
Beat until stiff: 2 eggs whites
1/4 cup sugar
Fold egg whites into lemon mixture.
Whip chilled milk until fluffy. Add 3 Tablespoons lemon juice and continue beating until stiff. Fold into lemon mixture. Gently spread into a 9 x 13 pan and sprinkle with 1/2 cup crushed vanilla wafers. Put into a freezer set at the coldest temperature for several hours. Cut into squares and garnish with mint or maraschino cherries.
My favorite new kitchen gadget is the Ultimate Microplane tool from Williams-Sonoma (http://www.williams-sonoma.com/products/microplane-ultimate-citrus-tool/?pkey=cfruit-vegetable-tools%7Cctlfvtfru). It makes grating lemon rind a breeze!
