How to Make Strained Tomatoes: A Step-by-Step Guide

Strained tomatoes, also known as passata or tomato puree, are a versatile ingredient that can be used as a base for soups, sauces, and stews. Making your own strained tomatoes not only allows you to control the quality and flavor but also provides a sense of accomplishment. In this article, we will guide you through the process of making strained tomatoes from scratch.

Step 1: Selecting the Right Tomatoes
To make a flavorful strained tomato sauce, it is crucial to choose ripe, firm, and juicy tomatoes. Look for varieties such as Roma, San Marzano, or vine-ripened tomatoes as they tend to have a higher flesh-to-seed ratio.

Step 2: Preparing the Tomatoes
Wash the tomatoes thoroughly under running water to remove any dirt or debris. Remove the stem and any blemishes or damaged parts. It is not necessary to peel or seed the tomatoes, as they will be strained later.

Step 3: Cooking the Tomatoes
Place the prepared tomatoes in a large pot and crush them using a potato masher or your hands. This will release the juices and help them cook evenly. Simmer the crushed tomatoes over low heat for about 30-40 minutes, stirring occasionally to prevent sticking or burning. This cooking process will help concentrate the flavors and reduce excess moisture.

Step 4: Straining the Tomatoes
Once the tomatoes have cooked down and become soft, remove the pot from heat. Set up a fine-mesh strainer or a food mill over a large bowl or pot. Pour the cooked tomatoes into the strainer, allowing the juice to separate from the solids. Gently press the solids with the back of a spoon to extract as much liquid as possible. Discard the solids or save them for other uses, such as making tomato paste or adding them to soups.

Step 5: Storing the Strained Tomatoes
Allow the strained tomato juice to cool completely before transferring it to sterilized glass jars or containers. Leave some headspace at the top to accommodate expansion during freezing or canning. Seal the jars tightly and store them in the refrigerator for up to a week. For longer-term storage, consider freezing or canning the strained tomatoes.
