Why This Recipe Works

Rather than add flavors and depth through the usual aromatics, we chose to focus on enhancing the carrots through caramelization. First, we cooked carrots with butter, a few thyme sprigs, sugar, and salt. As the butter's moisture evaporated, the milk solids began to brown. This occurred around the same time that the carrots began to caramelize and become well browned. To ensure that this soup could be pureed in a single go, we blended the cooked carrots with just half the liquid and then returned the mixture to the Dutch oven and thinned it out to our desired consistency with additional broth. As a finishing touch, we created a seasoned browned butter with some more fresh thyme, crushed coriander, cayenne, and lemon zest and juice for an elegant drizzle over each serving.
