Ingredients

1 cup sugar
1/2 cup butter
1 tablespoon lemon zest
1/4 cup lemon juice
3 eggs
3 cups flour

Preparation

In large bowl of an electric mixer, beat 1 cup of the sugar and butter until well blended.

Beat in eggs, 1 at a time, until smooth.
Gradually stir in 3 cups of the flour, mixing well. cover and chill until dough is firm enough to handle easily, at least 3 hours or as long as 2 days.
For easier handling, chill the dough before you form the ring-shaped cookies.
Divide dough in half. Cover and chill 1 portion.
Divide other half into 8 equal pieces. With floured fingers, roll each piece on a lightly floured board to make a 10-inch rope.
Overlap ends of each rope slightly to form a ring.
Place rings about 1 inch apart on a greased 14x17 inch baking sheet. Sprinkle light with sugar. Bake in a 300\u00b0F oven until golden, 35-40 minutes.
Remove cookies from pans and let cool completely on racks. Repeat with remaining dough.
Serve or store airtight up to 10 days.
