In the world of cooking, few ingredients pack as much flavor and versatility as tomatoes. Among the many forms tomatoes take in our kitchens, tomato purée and tomato paste are prominent. Both are staples in countless recipes, yet they serve distinct purposes and have unique characteristics. In this comprehensive article, we will explore the fundamental differences between tomato purée and tomato paste, their uses, production methods, and nutritional aspects. Understanding these differences can elevate your culinary creations and enhance your cooking techniques.
What is Tomato Purée?
Tomato purée is a smooth, liquid form of tomatoes made from crushed, cooked tomatoes that have been strained to remove seeds and skins. This product is typically thicker than tomato juice but thinner than tomato paste, sitting comfortably in the middle of the tomato product hierarchy.
Production Process of Tomato Purée
The production of tomato purée involves several key steps:
- Selection: Fresh, ripe tomatoes are selected for making purée, with more mature and flavorful varieties often preferred.
- Cooking: The tomatoes are cooked briefly to soften them, helping to break down the cell walls and release their juices.
- Blending and Straining: The cooked tomatoes are blended into a smooth mixture and passed through a sieve or strainer, discarding the seeds and skins to achieve a uniform texture.
- Packaging: The final product is packaged in cans, jars, or pouches and can be stored for extended periods.
With its smooth consistency and rich tomato flavor, tomato purée is beloved by cooks for sauces, soups, and take on various dishes that call for a hearty tomato presence.
What is Tomato Paste?
Tomato paste is a concentrated form of tomatoes that has been cooked down to eliminate a significant amount of water content. This results in a thicker consistency and a more intense flavor than tomato purée. Tomato paste is commonly used as a base for many recipes, enhancing flavor and color without introducing excess liquid.
Production Process of Tomato Paste
Creating tomato paste involves a more concentrated approach than purée:
- Selection: Similar to purée, high-quality tomatoes are crucial for paste, with paste tomatoes like Roma being popular.
- Cooking and Reducing: The tomatoes are cooked for a longer duration compared to purée, allowing for more water to evaporate and intensifying the flavor.
- Straining: After cooking, the tomatoes are strained to remove seeds and skins, similar to purée, but are then cooked further to achieve a denser pasty consistency.
- Packaging: Finally, the tomato paste is packaged and sealed, ready for use in various culinary applications.
This intensity of flavor makes tomato paste a robust option in cooking, perfect for adding depth and richness to dishes.
Key Differences: Tomato Purée vs. Tomato Paste
Understanding the differences between tomato purée and tomato paste is essential for knowing how to utilize each in cooking. Here are the primary distinctions:
Texture and Consistency
- Tomato Purée: Has a smoother, more liquid consistency, which makes it ideal for sauces and soups.
- Tomato Paste: Is denser and thicker, providing a concentrated flavor that can elevate a dish without adding excess moisture.

Substituting Tomato Purée and Tomato Paste
In many recipes, you might find yourself needing tomato purée and discovering that you only have tomato paste on hand, or vice versa. Understanding how to substitute one for the other can prove beneficial.
Substituting Tomato Purée for Tomato Paste
When using tomato purée instead of tomato paste, you may want to use about three times more purée to achieve a comparable flavor. However, since purée is thinner, it’s important to adjust the liquid content in your recipe to avoid a watery outcome.
Substituting Tomato Paste for Tomato Purée
When substituting tomato paste for purée, use only about one-third as much paste, and consider adding water to achieve a similar consistency. This approach helps maintain the desired sauce texture.
Which One Should You Use?
The choice between tomato purée and tomato paste often depends on the specific culinary needs and the dish you are preparing. Here are some points to consider for selecting the right tomato product:
- For Sauces: If you want a smooth and lighter sauce, tomato purée is your go-to choice. For more complex and robust sauces, especially in Italian cooking, opt for tomato paste.
- For Soups and Stews: Tomato purée works well in soups due to its smooth texture, while tomato paste can enhance the depth of flavor in stews and slow-cooked dishes.
- For Flavor Intensity: Use tomato paste when you want a sharp, concentrated tomato note without adding too much liquid. Opt for tomato purée for mild dishes.
Conclusion
In summary, tomato purée and tomato paste are both valuable ingredients in the culinary world, each bringing its own strengths and flavors to the table. Tomato purée is ideal for lighter, smoother applications, while tomato paste stands out for its intense flavor and ability to enrich dishes. Understanding when to use each product can significantly influence the outcome of your cooking, allowing you to create a variety of delicious meals.
Next time you reach for that can of tomatoes, ask yourself what experience you’re eager to create in your dish. Whether it’s the silky smoothness of tomato purée or the bold richness of tomato paste, your choice will undoubtedly enhance your creations and tantalize your taste buds. Happy cooking!
What is tomato purée?
Tomato purée is a thick liquid made from cooked and strained tomatoes. It has a smooth consistency, achieved by removing the seeds and skins, and is often used as a base for sauces, soups, and stews. The cooking process concentrates the tomato flavor while retaining a significant amount of moisture, making it less thick than tomato paste.
In cooking, tomato purée is favored for its richer flavor profile compared to crushed tomatoes or whole tomatoes. It acts as an excellent foundation for dishes that require a more pronounced tomato taste without the intense thickness that tomato paste would provide. Depending on the brand or preparation method, it can occasionally include added seasonings or preservatives.
What is tomato paste?
Tomato paste is a thick and concentrated product made from tomatoes that have been cooked for an extended period, removing most of their moisture content. The result is a paste with a deep flavor and reddish-brown color. It typically consists of tomatoes, salt, and sometimes citric acid, but is devoid of any skins or seeds, making it a smooth and rich ingredient.
Due to its concentration, tomato paste is often used in small amounts to enhance flavor in a variety of dishes such as sauces, casseroles, and soups. It can also be an excellent choice for recipes where you want to intensify tomato flavor without adding too much liquid, making it a versatile pantry staple for many home cooks.
What are the key differences between tomato purée and tomato paste?
The primary difference between tomato purée and tomato paste lies in their consistency and concentration. Tomato purée is thicker than crushed tomatoes but thinner than tomato paste. It retains some moisture content, which makes it suitable for recipes that require a rich tomato flavor without excessive thickness. In contrast, tomato paste is significantly thicker and more concentrated, delivering a punch of tomato flavor in a smaller volume.
In terms of usage, tomato purée is often a preferred choice for recipes that need a balanced tomato flavor with added moisture, such as in pasta sauces or soups. On the other hand, tomato paste is typically used in smaller quantities to intensify flavors, making it ideal for stews, casseroles, or any dish where you want to develop a richer tomato essence.
Can I substitute tomato purée for tomato paste?
Substituting tomato purée for tomato paste is possible, but it requires some adjustments due to their differing consistencies and concentrations. If you’re using tomato purée instead of paste, you’ll want to increase the amount, typically using about three times as much purée to achieve a similar level of tomato flavor. However, this substitution may also introduce additional moisture to your dish, so you may need to adjust cooking times or ingredients accordingly.
To maintain balance in recipes where thickening is crucial, it’s a good idea to cook down the tomato purée to reduce its moisture content. This will help in replicating the intensity of flavor that tomato paste provides without compromising the dish’s overall consistency and moisture level.
Which one should I use for sauces?
When it comes to making sauces, the choice between tomato purée and tomato paste depends on the desired thickness and flavor intensity of your sauce. Tomato purée is an excellent option for marinara or tomato-based sauces where a smoother texture and less intense flavor are preferable. Its moderate moisture content allows the sauce to remain pourable and easy to use over pasta or in stews.
In contrast, if you are looking to create a sauce with a robust and concentrated tomato flavor, tomato paste is the way to go. It will thicken the sauce significantly and provide a richer tomato taste that can enhance dishes like lasagna or meat sauces. Depending on your recipe requirements, you may also combine the two for a more balanced flavor and texture.
How should I store leftover tomato purée or paste?
To ensure the freshness and longevity of leftover tomato purée or paste, proper storage is crucial. Both products should be transferred to an airtight container after opening if purchased in cans or jars. Tomato purée can typically last in the refrigerator for up to five to seven days when stored properly, while tomato paste may last about a week, especially if you use a small amount and reseal tightly.
For longer storage, consider freezing tomato paste in ice cube trays to allow for easy portioning. Once frozen, transfer the cubes into a zip-lock bag for up to six months. Tomato purée can also be frozen in a similar manner. By preparing these ingredients for longer-term storage, you can reduce waste and always have them on hand for future recipes.
Are there any nutritional differences between tomato purée and tomato paste?
While both tomato purée and tomato paste are derived from tomatoes and share similar nutritional benefits, there are slight differences in their nutrient content due to their concentrations. Tomato paste has a higher concentration of vitamins and minerals per serving, especially vitamin C and lycopene, which is a powerful antioxidant. This concentration occurs because tomato paste is made from cooked tomatoes with most water content removed.
On the other hand, tomato purée, while still nutritious, has a higher moisture content, which can dilute its nutrients a bit compared to tomato paste. However, both options are low in calories, fat-free, and contain beneficial compounds that can improve heart health and reduce the risk of certain diseases. Including either in your diet can contribute positively to your overall nutritional intake.
