When Sitka Salmon sent me loads of fish to cook with this year in preparation for a project we were working on, I started working on a few great ways to use frozen fish, especially white-fleshed fish like black rockfish and cod. Making a topping with dried black trumpets, leeks and tomatoes was one of my favorite preps on the first round of things I made, and it is a great method you can apply to lots of fish, using a number of different mushrooms.
Black trumpets take well to a lot of preparations, but one of the best parts about them is that they dry and rehydrate like a dream, making cooking with dehydrated ones really easy, so they were the first mushrooms I reached for here. Other mushrooms with a similar structure like yellowfoot chanterelles, as well as things like porcini could work well here too though.
The recipe itself I started working on after I was flipping through an old book by Swiss chef Fredy Girardet, a favorite chef of mine in the world of old-school masters. The dish had no image, but I could see it in my mind. It was just a simple dish of freshly caught white fish (bream I believe) baked with a topping of freshly cooked garden vegetables referred to as a crust.
In America we hear the word crust and think crisp, or crunchy, but here it’s used more in the sense of a juicy topping that keeps the fish juicy as it cooks. Tweaking it around a bit wasn’t difficult at all, and the black mushrooms make a great contrast to some white fleshed fish. It’s a great way to use some dried mushrooms, and you could use the topping on a number of different things, for example:
- Chicken cutlets
- On top of slices of baked pumpkin or potatoes, baked the same way as a gratin
- Take a slice of good bread and toast it, then top with the mushroom topping, maybe some grated cheese, and bake. Cut into wedges and serve as an appetizer.
- The black trumpet-veggie mixture, without the breadcrumbs, would make a great foccaccia or flatbread topper.
- Use the mushroom filling, along with some cheese, to stuff tomatoes that have been halved and had their seeds removed, then bake until browned per usual.
