Section 1: What is Sous Vide Cooking?

Sous vide, which translates to “under vacuum” in French, is a cooking method that involves sealing food in airtight bags and immersing it in a water bath at a constant temperature. This technique was first developed in the 1970s by French chef Georges Pralus, who discovered that vacuum-sealed foods preserve moisture and enhance flavor while cooking.

Over the years, sous vide cooking has evolved with advancements in technology, making it accessible to home cooks. The advantages of sous vide for cooking fish include:

• Precise temperature control: Prevents overcooking and ensures perfectly cooked fish.
• Enhanced flavor: The vacuum-sealed bag traps seasonings and flavors, allowing for infusions.
• Improved texture: Fish cooked sous vide remains tender and flaky, avoiding the dryness associated with traditional cooking methods.

Section 2: Choosing the Right Fish Fillets

Not all fish are created equal when it comes to sous vide cooking. Some types are better suited for this method due to their texture and fat content. Here are some of the best options:

• Salmon: Rich and fatty, perfect for a buttery texture.
• Cod: Mild flavor with a flaky texture; great for versatility.
• Tilapia: Mild and versatile, ideal for various seasonings.
• Halibut: Firm and meaty, holds up well during cooking.

When choosing fish, freshness and quality are paramount. Look for fish that is bright in color, has a clean ocean scent, and is firm to the touch. Always opt for sustainably sourced fish whenever possible.

Section 3: Essential Sous Vide Equipment

To embark on your sous vide journey, you’ll need a few essential tools:

• Sous vide immersion circulator: The heart of sous vide cooking, it heats the water and maintains the desired temperature.
• Vacuum sealer or zip-lock bags: To seal your fish and seasonings, preventing water from entering.
• Containers for water bath: Use a large pot or a dedicated sous vide container to hold the water.

Optional tools can enhance your sous vide experience:

• Blow torch: For achieving a crispy exterior after cooking.
• Digital thermometer: To double-check the internal temperature.
• Weights: To keep bags submerged in the water bath.

Preparation is key to achieving delicious sous vide fish. Follow these steps:

1. Clean the fish fillets under cold water and pat them dry with paper towels.
