Rhubarb Cookies Recipe

+ Directions : ** To cook rhubarb: Use a proportion of 4 cups sliced rhubarb cut in 1/2-inch pieces to 1 cup sugar. Toss the rhubarb and sugar together and let steep overnight (you will be amazed at how much juice the rhubarb gives off). Pour off 3/4 cup of the liquid and use for a drink. Cook the rhubarb slices in the remaining until just tender but still holding their shape, less than 5 minutes. The rhubarb is ready to eat as is, to use in other recipes, or to freeze in containers. Cream the butter and sugar together. Add the egg and beat until light, then stir in the rhubarb. Stir the flour, salt, baking soda, and spices together and toss until thoroughly mixed. Stir the dry ingredients into the rhubarb mixture until the two are blended, then fold in the optional ginger, the walnuts, and the raisins. Drop the batter by the tablespoonful onto greased baking sheets about 1 1/2 inches apart, and bake in a preheated 350 F oven for 12 minutes, until lightly browned at the edges. Makes about 30 cookies. [ The L. L. Bean Book of NEW New England Cookery ]
