Beat egg whites, salt and cream of tartar until very firm. Gradually add sugar and mix. Fold in Chocolate chips. To prevent burning you can bake on an air-space cookie sheet or put brown grocery bag on regular cookie sheet. Drop by teaspoon fulls on pan. Bake 150ºC or 25 minutes. They should only be lightly browned.

This recipe can be doubled, but if you do that don't double the chocolate chips. Best if used in a few days.
