Ingredients

• 1 package of halibut, rockfish, or cod thawed, rinsed and patted dry

• Salt

• 1 yellow squash

• 1 large cucumber

• 3 to 4 French breakfast radishes

• 8-10 cherry tomatoes halved or quartered

• 1/4 cup white wine or rice vinegar

• 1 pound unsalted butter

• Olive oil (optional)

• Black pepper

• Fresh herbs such as parsley, basil, or cilantro

Instructions

• Season the fish well and set aside. Slice the squash, cucumber and radishes very thinly into rounds, ideally with a mandolin -- although a knife is fine. Toss all the vegetables including the tomatoes, with a little salt and vinegar and set aside.

• Melt the butter in a pot large enough to hold at least 1 piece of fish, and ideally 2, at a time, but small enough so that the pieces of fish are submerged. You can use more butter if you want to, or you can top things off with olive oil. You want the butter to be between 150°F and 170°F. When the butter hits the right temperature, pat the pieces of fish dry with paper towels and submerge in the oil. If the fish sizzles at all, lower the heat. You want the fish to cook gently. Let the fish swim in the butter for about 5-6 minutes for every 1/2 inch of thickness. With one minute left of cooking, add in the fresh herbs.

• To finish the salad, add a little bit of the melted butter, or use olive oil, and toss well. Put some on everyone's plate. Gently lift out the pieces of fish and lay them on the salad. Grind lots of black pepper over everything. Serve with some good crusty bread.
