This is a recipe from my great-aunt. I'm glad I pulled it out to post, it's written in pencil and so old that it's practically faded away and due for a reprinting! They are a very different delicious cookie.

Lemon Leaves

1/2 cup butter
1 1/3 cup sugar
1 egg
1 Tablespoon cream
1 teaspoon lemon extract
2 1/4 cups flour
3 teaspoons baking powder
1/2 teaspoon salt
2 egg yolks
1 teaspoon water
1 1/2 teaspoons grated lemon rind
1/4 cup finely chopped pistachio nuts
Preheat oven to 350.
Cream butter & 1 cup sugar. Add 1 egg, cream and extract. Combine flour, baking powder and salt. Add flour mixture to butter sugar mixture to make a soft dough. Chill several hours or overnight. Roll out, very thin, 1/4th at a time. Cut with small leaf cookie cutter or other small cookie cutter of your choice. Bake at 350 for 6-7 minutes. This cookies stick, the trick my aunt used was to open the oven door, pull the pan partially out of the oven and lift the cookies off the sheet while still hot. Perhaps this will not present a problem now with the advent of non-stick coating spray or one of the Silpat type pan liners. I began using nonstick coating when it became available but still do the oven door trick perhaps out of homage to my aunt rather than necessity!) When cookies have cooled, brush with them with a mixture of the two egg yolks and teaspoon of water. Then sprinkle immediately with the lemon zest and finely chopped nuts.
