He melts some butter on the iron, drops a gob of dough on, closes it, and leaves it on the open flame for twenty seconds or so, flipping the iron midway through and cooking for another twenty seconds.
It takes up to ten minutes for the iron to get good and hot, so the first half dozen cookies weren't golden brown like they ideally would be.
Here's my grandparents' recipe, should you like to try your hand with an electric iron like this one (or look for an old-school iron on eBay, knock yourself out):
6 eggsWhisk eggs and add sugar gradually, beating until smooth. Add cooled butter and flavoring. Sift flour and baking powder together and add to egg mixture. Dough should be sticky enough to drop by spoonful.
3 1/2 cups flour
1 1/2 cups sugar
1 tsp. baking powder
2 tbsp. vanilla or anise
1/2 lb. butter or margarine
half orange rind and juice
My crazy 84-year-old grandfather doubled this recipe and stood at the stove for four and a half hours without a break, baking these pizzelles one at a time, blithely ignoring our pleas for him to sit down and rest. Crazy, I tell you.
They taste great with eggnog.
