Since you state that you do not keep Shabbos, and you state that you want to give it to your 'kosher friends', implying that you do not necessarily keep kosher, there is another problem. Even if you had made this during the week, it would be the same as if you had cooked food in your kitchen, using your own utensils. Even if the food was bought from a kosher grocery, they would not be able to use it. Since you could have used the equipment for wine distillation (whether you have or not), the equipment itself cannot be assumed to be kosher.
I would suggest that if you want to make some for them, you do so with new equipment, in their house, under their supervision. (and not on Shabbos).
