Cook techniques
Roasting Vegetables
Roasting is a method that enhances the natural sweetness and flavor of vegetables. For the sweet potato soup, quickly toss the sweet potatoes and red onions in oil and salt before placing them in a preheated oven. This technique allows for caramelization, creating a rich and savory base for the soup.

Blending is essential for achieving a smooth and creamy texture in soups. After roasting, transfer the sweet potatoes, red onions, vegetable broth, ginger, and nuts to a blender. Blend until fully combined and silky, ensuring a delightful mouthfeel.
Crumbling Cauliflower
Crumbling is a technique used to create texture in dishes. Once the cauliflower has roasted and gained some color, break it into smaller pieces using a wooden spoon or spatula. This not only creates visual interest but also enhances the eating experience when added as a topping.
Adjusting Seasoning
Tasting and adjusting seasoning is crucial in cooking. After blending the soup, taste it and add salt or any other seasoning as needed. This step ensures that the final dish is well-balanced and flavorful.
