Vacuum packaging and sous-vide
A perfect combination for perfect meals
Vacuum packaging and sous-vide is a powerful combination that helps you cook with precision and achieve the perfect texture. In this guide, we explain how vacuum sealers are used for sous-vide cooking and what benefits you can get when you combine these techniques.
What is sous-vide?
Sous-vide is a cooking method where the food is vacuum packed and cooked slowly in a water bath at a precise temperature. The technique is often used by professional chefs to ensure that food is cooked evenly and retains all its flavor and juiciness. By cooking at a precisely controlled temperature, you avoid overcooking or the food becoming dry.
Why use vacuum packaging for sous-vide?
Vacuum packaging is a necessary step for sous-vide cooking. By vacuum packaging the food, an oxygen-free environment is created, which prevents bacteria from growing and preserves flavor and nutrients during the cooking process. The vacuum packaging also allows marinades and spices to penetrate better into the ingredients, which gives a richer taste.
- Preserves nutrients and taste: By vacuum packaging before sous-vide cooking, all nutrients and flavors are retained in the food.
- Even cooking: Vacuum packaging means that the food is in even contact with the water bath, which provides even and perfect cooking.
- Improves marinating: The vacuum allows marinades and spices to be better absorbed into the food during sous-vide cooking.
Step-by-step guide to cooking sous-vide with vacuum packaging
1. Prepare the ingredients
Start by preparing the ingredients. If you want to marinate meat or vegetables, you can do it directly in the vacuum bag. Add spices, oil, butter or other flavoring agents before sealing the bag.
2. Vacuum pack the food
Use a vacuum sealer to seal the bag and remove all air. This creates the oxygen-free environment required for sous-vide cooking and prevents the food from floating up in the water bath.
3. Set the correct temperature
Fill your sous-vide water bath and set the correct temperature for the type of food you are cooking. For example, you can cook meat at 55-60°C for medium-rare or vegetables at 85°C.
4. Cook the food slowly
Let the food cook slowly for several hours depending on what you are cooking. Thanks to the precise temperature, the food is perfectly cooked without the risk of overcooking.
5. Finish by browning
When the sous-vide cooking is complete, remove the food from the bag and brown it quickly in a hot pan if you are cooking meat. This gives a nice surface and extra flavor without affecting the internal juiciness.
What types of food are best for sous-vide?
Sous-vide is versatile and can be used for a variety of foods. Here are some examples of what works best for sous-vide cooking:
- Meat and poultry: Perfect for cooking steak, chicken, pork and lamb with perfectly even temperature and juiciness.
- Vegetables: Keeps vegetables crunchy and full of nutrition during the cooking process.
- Fish and shellfish: Sous-vide cooking provides a delicate and even cooking of fish and shellfish without overcooking them.
