Pat the sea bass with paper towels to remove any excess moisture.
Sprinkle with salt to taste.
Place sea bass steaks in a vacuum bag with a tablespoon of butter on top of each piece of fish.
Vacuum and seal the fish.
Heat sous vide water to your desired temperature. I recommend 130 F.
Submerge the bag in the sous vide water and set the timer for 30 minutes per inch of thickness.
Once cooked, remove from the bag and sear in a screaming hot pan with butter to make the perfect crust on the fish.
In a hot pan add the olive oil, anchovy paste, garlic on onions. Cook until softened and the anchovy paste has dissolved.
Add the capers, corn, olives and tomatoes.
Bring to a bubble and when the tomatoes have burst, add the chili flake.
Serve alongside the sous vide sea bass.
