To make tomato puree, simmer fresh tomatoes until softened, then blend until smooth. Strain the puree to remove seeds and skins for the best consistency and flavor.
Detailed Explanation:
Creating tomato puree from scratch is a simple process that yields a flavorful base for sauces, soups, and more. Here's a step-by-step guide:
- Choose Ripe Tomatoes: Select ripe, juicy tomatoes. Roma or San Marzano tomatoes are excellent choices due to their meaty texture and low seed content.
- Prepare the Tomatoes: Wash the tomatoes thoroughly. You can remove the skins for a smoother puree. To do this, score an 'X' on the bottom of each tomato, then blanch them in boiling water for 30-60 seconds. Immediately transfer them to an ice bath. The skins should peel off easily.
- Chop the Tomatoes: Roughly chop the tomatoes into smaller pieces. This will help them cook down more quickly and evenly.
- Simmer the Tomatoes: In a large pot or Dutch oven, combine the chopped tomatoes with a pinch of salt and any desired aromatics (such as garlic, onion, or herbs). Bring the mixture to a simmer over medium heat.
- Cook Until Softened: Reduce the heat to low and simmer the tomatoes, uncovered, for 30-60 minutes, or until they are very soft and have released their juices. Stir occasionally to prevent sticking.
- Blend the Mixture: Once the tomatoes are softened, carefully transfer the mixture to a blender or use an immersion blender to puree until smooth. Be cautious when blending hot liquids; vent the blender lid to prevent pressure buildup.
- Strain the Puree (Optional but Recommended): For the smoothest puree, strain the blended mixture through a fine-mesh sieve or cheesecloth-lined colander. This will remove any remaining seeds and skins, resulting in a silky texture. Discard the solids left in the sieve.
- Adjust Seasoning: Taste the puree and adjust the seasoning as needed. Add more salt, pepper, or herbs to your liking.
- Cool and Store: Allow the tomato puree to cool completely before storing it in an airtight container in the refrigerator for up to 5 days, or in the freezer for longer storage.
Pro Tip:
Roast the tomatoes before simmering to intensify their flavor. Toss the prepared tomatoes with olive oil, salt, pepper, and herbs, then roast at 400°F (200°C) until softened and slightly caramelized before proceeding with the simmering and blending steps. This adds a depth of flavor that elevates the final puree.
