As per last time, this recipe has fish. This recipe can really easily be done without the fish, that said. I've done it many times as a veggie dish, too. Very delicious either way!
Please note that I rarely cook with quantities... So the chances of getting precise units from me are very low... I cook by mostly instinct (and sometimes from a recipe research to know more about a basic idea , just like today's croquettes!), and so I suggest you do it also!
