Preheat pizzelle iron. Cream together eggs and sugar, then add melted margarine that has been cooled and anise extract. Add flour and baking powder and mix until smooth. Add anise seeds and mix well. If batter is too thick add water a tablespoon at a time until it is the desired consistency. Using a teaspoon, drop one spoonful of batter on iron for each cookie. Hint: I place the batter in a Ziploc bag and snip off one small corner (like a pastry bag) and squeeze out a teaspoon-sized dollop on the iron for each cookie. It gives you better control and is MUCH less sticky. And clean-up, well... much easier!
