About 48 (2-inch) cookies

Preheat oven to 375 degrees F.

Sift:
2/3 cup granulated sugar

Beat until soft:
1/3 cup butter

Add the sugar gradually. Blend these ingredients until light and creamy. Beat in:
1 whole egg
6 tablespoons orange marmalade.

Sift:
1 1/2 cups all-purpose flour

Resift with:
1 1/4 teaspoons double-acting baking powder

Stir sifted ingredients into the butter mixture. Drop batter from a teaspoon, well apart, on a greased sheet. Bake the cookies for about 8 minutes. It is difficult to prescribe the right amount of flour, as marmalades differ a great deal in consistency. Follow the rule, then try out 1 or 2 cookies. If they are too dry, add a little more marmalade, if too moist, a little more flour and some grated lemon rind.
