In the 18th century, 1 sou was equivalent to 1/20 of a livre, which was the currency used in France before the introduction of the euro. Therefore, to convert 18 sous to euros, we would need to know the exchange rate between the livre and the euro at that time. Without that information, it is not possible to accurately determine the equivalent amount in euros. **

To cook sous vide, you will need a sous vide machine or immersion circulator, a vacuum sealer or resealable bags, and a pot or container. First, season your food and place it in a vacuum-sealed bag or resealable bag. Then, use the vacuum sealer to remove the air from the bag and seal it, or use the water displacement method to remove the air from the resealable bag. Next, attach the sous vide machine to the pot or container and set the temperature and cooking time according to your recipe. Once the water reaches the desired temperature, place the sealed bag in the water and cook the food for the specified time. Finally, remove the bag from the water, open it, and finish the food by searing, grilling, or broiling it for a crispy exterior. **

A sous chef, also known as a second chef, is the second-in-command in a professional kitchen. They work directly under the head chef and are responsible for overseeing the day-to-day operations of the kitchen, including food preparation, cooking, and staff management. Sous chefs often have specialized culinary training and experience, and they play a crucial role in ensuring that the kitchen runs smoothly and that dishes are prepared to the highest standards. **

Steaks are pre-cooked with sous vide by vacuum-sealing the steak in a bag with seasonings and then cooking it in a water bath at a precise temperature for an extended period of time. This ensures that the steak is cooked evenly and to the desired level of doneness. Once the steak is cooked sous vide, it is then quickly seared on a hot grill or pan to develop a flavorful crust on the outside while keeping the inside perfectly cooked. This method helps to achieve a tender and juicy steak with consistent results every time. **
