Cooking large cuts of meat, maintaining consistent quality, and achieving high yield can be challenging for any professional kitchen. Fortunately, advanced technology in professional combi ovens, like the Invoq oven, offers a solution that benefits both kitchen efficiency and food quality. Let’s explore how Delta-T cooking can transform your culinary outcomes.
What is Delta-T cooking?
Delta-T is a cooking method that uses precise temperature control, ensuring the oven’s temperature rises gradually based on the core temperature of the food. The oven gently raises its temperature to match the core temperature as it cooks, enabling a slow, even cook. This process enhances tenderness and juiciness, especially for tough cuts of meat, maximizing yield and reducing shrinkage.
Key benefits of using Delta-T cooking in Invoq Combi ovens
1. Maximum yield
With Delta-T, you can increase the yield by up to 12%. The slow cooking process preserves moisture, reducing shrinkage and providing more portions from the same amount of meat, translating into significant cost savings.
2. Consistent food quality
Delta-T ensures that each dish is cooked evenly throughout. This consistency is essential in a professional kitchen, where high standards and repeatability matter.
3. Tender & flavorful results
By cooking at a controlled low temperature, Delta-T allows enzymes in the meat to tenderize it naturally, resulting in an enhanced, flavorful bite. It’s ideal for serving high-quality dishes without additional seasoning or sauces.
4. Efficient use of time
Adding Cook & Hold to your Delta-T cooking offers the flexibility of overnight cooking. The oven works during non-productive hours, giving you perfectly cooked meat the next morning. This reduces daytime cooking pressure, allowing your kitchen staff to focus on other tasks.
5. Energy savings
By running at low, controlled temperatures, Delta-T Cook & Hold uses less energy than traditional high-heat cooking methods. This translates to energy cost savings, a sustainable practice that aligns with the demands of modern commercial kitchens.
How does Delta-T work?
In Delta-T cooking, you set the oven’s temperature relative to the food’s core temperature. For example, if the core temperature is 20°C, you set the oven to have a delta temperature of 20°C above it, meaning the oven initially heats to 40°C.
As the core temperature rises, the oven’s temperature gradually follows until the desired doneness is achieved. This slow, steady approach delivers uniform cooking without the need for a resting period.
