Cream margarine and peanut butter. Stir in sugar and egg. Beat in remaining ingredients. Knead dough a few times on a floured board. Cut dough into 40 pieces. Shape each piece with hands into a roll 6 cm long and 2 cm in diameter. Pinch in the center and place on cookie sheet. Flatten top of cookies and round one end and pinch the other one to resemble the shape of a peanut in the shell. With the back of a knife, cut shallow crisscross lines on top of cookie. Cookies should be at least 5 cm apart since they spread during baking. Bake 190ºC for 10-12 minutes. ----
