Cream the butter and 1-3/4 cups sugar. Add the eggs and vanilla. Beat well. Combine the flour, baking powder, salt, and herbs. Add to the creamed mixture and mix. Drop dough by teaspoonfuls, 3 inches apart, on a greased cookie sheet. Flatten slightly with a fork or cup bottom. Sprinkle lightly with the remaining sugar. Bake at 350 degrees for 8 to 10 minutes or until barely browned. Cool slightly, then remove to a rack.
The total amount of herbs used is 1/3 cup. Use any lemon combo you like. Mints and a bit of rosemary chopped would also be good in this too.
