Timeless Classics from a Modern Kitchen: Lemon Bars in the VC5 Convection Oven

In a world where smart kitchen equipment is becoming increasingly popular, it’s easy to overlook the importance of traditional equipment like convection ovens. However, the time-tested Vulcan VC5 Convection Oven remains a cornerstone of a professional kitchen, offering unmatched reliability and performance. 

Perfectly Even Cooking Every Time

Unlike conventional ovens that can be a hit or miss with hot spots, the VC5 uses a fan to circulate hot air throughout the oven’s cavity. Featuring a patented snorkel tube, it ensures consistent heat distribution across every part of the dish. This eliminates the need to turn the product halfway through the cooking process, guaranteeing perfectly cooked meals every time. 

Faster and More Efficient

The Vulcan VC5’s patented and award-winning design also ensures both speed and efficiency in cooking and baking. Its fan is uniquely positioned on the back wall, which helps to optimize airflow within the cavity. The patented snorkel moves hot air generated by the oven more efficiently through the cabinet, ensuring rapid and even cooking results. This efficiency is even backed by its ENERGY STAR certification! 

Easy Maintenance and Cleaning

Maintaining the Vulcan VC5 convection oven is easy. Spot cleaning can be done throughout service and for deeper cleaning at the end of the day the Grab-and-go oven racks, stainless steel drip pans, and oven doors are all dish washer safe making for easy clean up. 

Super Versatile

From the ever so popular cooking competitions to K-12 kitchens, versatility is where the Vulcan VC5 truly shines. This oven can handle a variety of cooking tasks, from baking and roasting to broiling and dehydrating. Its flexibility makes it an all-star in any kitchen, allowing chefs to experiment with different cooking techniques and recipes.  Whether you’re baking delicate pasties or roasting a huge batch of vegetables, the VC5 has you covered. 

Enhanced Flavor and Texture

Thanks to its even cooking and efficient heat distribution, the Vulcan VC5 enhances the flavor and texture of your dishes. The consistent heat helps lock in moisture, making meats juicer and baked goods more flavorful. Control is at your fingertips with the fan switch:  a “High” setting, perfect for roasting, baking or achieving a crispy texture, and a “Low” setting, ideal for delicate dishes that require a more controlled and slower cooking process, like custard or pastries.
