I flavored mine with chocolate chips and walnuts but I felt they lacked any true punch of flavor. Next time I would add 1/2 teaspoon of ground cinnamon (Saigon preferred for a good flavor kick) and up to 100 grams of raisins. Give this a shot if you decide to test out this recipe yourself.
Also, if adding chocolate chips, be prepared for melting. Just fold them in gently with a rubber spatula and then scoop up into drop cookies asap before they melt any further.
To get started you will need a fair sized deep dish skillet, saucepan (large enough to hold all the ingredients) or even a small dutch oven will do. I whisked in most of the ingredients initially with my wire whisk but once you add the flour you will need to switch over to a wooden spoon. Finally, switch over again to a rubber spatula when adding your fruits, nuts, chocolate, etc.
So let's get started !
