Yes, tomatoes can be used in two stages of cooking to develop different flavors. Cooking them at different times and in different ways unlocks unique flavor profiles.
Using tomatoes in two stages allows you to build layers of flavor in your dish. Here's how it works:
First Stage: Deep, Roasted Flavor: Start by roasting tomatoes at a high temperature (around 400°F or 200°C) with olive oil, garlic, and herbs. Roasting concentrates the sugars and creates a rich, caramelized flavor. This initial roasting process brings out the umami and sweetness in the tomatoes.
Second Stage: Fresh, Bright Acidity: Later in the cooking process, add fresh, uncooked or lightly cooked tomatoes. This could be diced fresh tomatoes, a quick tomato sauce made with fresh tomatoes, or even a tomato confit. This second addition provides a burst of fresh acidity and brightness that contrasts with the deep, roasted flavor from the first stage.
Combining the Flavors: By combining these two preparations, you achieve a complex flavor profile. The roasted tomatoes provide depth and richness, while the fresh tomatoes offer a vibrant, tangy counterpoint. This technique works well in pasta sauces, stews, soups, and even on pizzas.
When using canned tomatoes, consider roasting them briefly before adding them to your dish to enhance their flavor. Canned tomatoes can sometimes lack the depth of fresh tomatoes, and roasting can help to concentrate their sweetness and umami.
