I adopted this recipe after its original poster, mean chef, departed the site. Mean posted it on jan 1, 2004.

Sift flour with baking powder , baking soda and salt.

In large bowl of electric mixer , cream butter and sugar , add egg and beat on medium speed until light and fluffy.

At low speed , beat in sour cream , lemon extract and grated lemon zest until smooth.

Gradually add flour mixture , beating until well combined.

Form dough into a ball , wrap in foil and refrigerate overnight.

Divide dough into 4 parts.

Refrigerate until ready to roll out.

On floured surface roll dough , one part at a time , 1 / 4-inch thick.

Using a 2 to 3-inch cookie cutter or glass , cut out cookies.

Use a spatula to carefully pick up and place cookies on a parchment lined sheet pan 2 inches apart.

Lightly brush cookies with lemon juice and sprinkle with additional sugar.

Bake in preheated 375-degree oven for 10-12 minutes until golden brown.

Do not overcook.

Remove cookies to wire rack to cool completely.

Bake each portion completely before rolling another batch.
