So, I have a dinner party coming up, where I intend to serve sous vide steak, and some beef shin croquettes (along with a few other bits of course!). One of my good friends is a pescetarian, and rather than cooking veggie dishes, I usually try and do fish for her. So, what do I replace the steak and the beef shin with? I'm thinking to replace the steak with a meaty fish like sea bass, salmon, or cod, and pan fry it. That way it will still go with the chimichurri sauce I'm doing. For the croquettes, I'm thinking of replacing the beef shin with salmon or cod. The specific bit I would invite helpful comments on is the croquettes - say I do go for salmon or cod, how do people suggest I prepare it? Just a simple milk poach before flaking and mixing with the potato, or something more jazzy? Thanks!
