How to Sous Vide Kohlrabi for a Unique Side Dish

Introduction

Sous vide cooking is a technique that has taken the culinary world by storm, allowing home cooks and professional chefs alike to achieve incredible precision and control in their cooking. By sealing food in a vacuum-sealed bag and immersing it in a water bath at a precise temperature, sous vide ensures that your meals are cooked consistently and evenly, preserving both flavor and nutrients.

One vegetable that benefits immensely from this technique is kohlrabi, a unique and versatile cruciferous vegetable. With its crisp texture and mildly sweet flavor, kohlrabi can be transformed into a delectable side dish when prepared using the sous vide method. In this article, we will explore the ins and outs of sous vide kohlrabi, its nutritional benefits, and how to prepare it for a delightful culinary experience.

What is Kohlrabi?

Kohlrabi, also known as turnip cabbage, resembles a bulbous root vegetable but is actually the swollen stem of the plant. Its appearance ranges from green to purple, with a smooth skin that encases a crisp and crunchy interior. The taste of kohlrabi is often described as a cross between a cabbage and a radish, offering a refreshing and slightly peppery flavor that can be enjoyed raw or cooked.

Nutritional Benefits of Kohlrabi

• Low in calories and high in fiber, aiding digestion.
• Rich in vitamin C, promoting a healthy immune system.
• Contains antioxidants that can help reduce inflammation.
• High in potassium, supporting heart health and blood pressure regulation.

Popular Culinary Uses

Kohlrabi can be used in a variety of dishes, including:

• Salads, where it adds a crunchy texture.
• Stir-fries, providing a satisfying bite.
• Soups and stews, enhancing the overall flavor profile.
• Purees and fritters, offering a unique twist on traditional recipes.

Why Sous Vide?

The sous vide cooking technique has gained popularity for good reason. It involves cooking food slowly and accurately in a temperature-controlled water bath. This method brings several advantages to the table:

Advantages of Sous Vide

• Precision: Sous vide allows you to cook kohlrabi (and other ingredients) to the exact desired doneness.
• Control: You have complete control over the cooking temperature, ensuring that kohlrabi is never overcooked.
• Consistency: Each batch of kohlrabi can be cooked to the same level of tenderness and flavor.

Comparison with Traditional Cooking Methods

Traditional cooking methods, such as boiling or steaming, can often lead to uneven cooking and nutrient loss. In contrast, sous vide preserves the nutrients while enhancing the vegetable’s natural flavors.

Step-by-Step Preparation

1. Selecting the Right Kohlrabi
   • Choose firm and unblemished kohlrabi bulbs with greens still attached, if possible.

2. Peeling and Cutting

   To peel and cut kohlrabi:
