ok, ive been a barista for a few months now. ive been trying to do this latte art thing for a while now and its really getting to me. im sure that i can steam the milk properly, ive read a few books on making coffee drinks, but none of them have explained how to perform latte art. Is there a certain milk i should use? ive tried ever milk in the book. is there a certain pitcher i should use? i use a 20oz. pitcher. is there a certain way i should pour it? can the espresso affect the latte art? im overwhelmed.
