What is a tomatillo and how does it differ from a tomato?
The tomatillo is a fascinating fruit that belongs to the nightshade family, which also includes tomatoes, peppers, and eggplants. While it is often compared to the tomato, the tomatillo is a distinct species with its own unique characteristics. One of the main differences between the two is the papery, lantern-like husk that covers the tomatillo, which is not found on tomatoes. This husk is actually a modified calyx, a part of the flower that protects the fruit as it grows. In terms of flavor and texture, tomatillos are also distinct from tomatoes, with a sweeter, slightly tart taste and a firmer, more dense flesh.
In addition to their physical and culinary differences, tomatillos and tomatoes also have distinct botanical and cultural histories. Tomatillos are native to Mexico and Central America, where they have been an important food source for thousands of years. They were a staple crop in many indigenous cultures, including the Aztecs and Mayans, who prized them for their flavor, nutrition, and versatility. In contrast, tomatoes were first domesticated in South America, and were later introduced to Europe by Spanish conquistadors, where they became a staple ingredient in Mediterranean cuisine. Today, both tomatillos and tomatoes are enjoyed around the world, but they remain distinct and important components of their respective culinary traditions.
Where did tomatillos originate and how were they first used as a food source?
Tomatillos are native to the highlands of Mexico and Central America, where they have been cultivated for thousands of years. The earliest evidence of tomatillo cultivation comes from archaeological sites in southern Mexico, where the fruit was found in the remains of ancient cooking vessels and ceremonial offerings. It is believed that tomatillos were first domesticated by the ancient ancestors of the modern-day Mayans and Aztecs, who prized the fruit for its flavor, nutrition, and versatility. In these cultures, tomatillos were not only a staple food source, but also played a significant role in traditional medicine, ritual, and spiritual practice.
In terms of their early use as a food source, tomatillos were often eaten raw, roasted, or cooked in a variety of dishes, including soups, stews, and sauces. They were also dried, smoked, or fermented to preserve them for later use, allowing the fruit to be enjoyed year-round. One of the most famous traditional dishes featuring tomatillos is the Mexican sauce known as “salsa verde,” which is made by cooking the fruit with onions, garlic, and chili peppers to create a spicy, slightly sweet condiment. This sauce remains a staple of Mexican cuisine to this day, and is often served with tacos, grilled meats, and other traditional dishes.
What are some of the key nutritional benefits of tomatillos?
Tomatillos are a nutrient-rich food that provides a range of essential vitamins, minerals, and antioxidants. One of the key nutritional benefits of tomatillos is their high content of vitamin C, which is important for immune function, skin health, and iron absorption. They are also a good source of potassium, a mineral that helps to regulate blood pressure and support healthy heart function. In addition, tomatillos contain a range of phytochemicals, including flavonoids and carotenoids, which have been shown to have anti-inflammatory and antioxidant properties.
In terms of their overall nutritional profile, tomatillos are relatively low in calories and fat, making them a great addition to a healthy diet. They are also a good source of dietary fiber, which can help to support digestive health and promote feelings of fullness and satisfaction. One of the most interesting nutritional aspects of tomatillos is their high content of a compound called withanolides, which has been shown to have anti-cancer and anti-inflammatory properties. While more research is needed to fully understand the health benefits of withanolides, they are thought to contribute to the fruit’s potential as a nutritious and medicinal food.
How are tomatillos typically cooked and prepared in traditional Mexican cuisine?

One of the most common ways to cook tomatillos is to roast them, which brings out their natural sweetness and depth of flavor. To do this, the tomatillos are simply placed on a baking sheet and roasted in a hot oven until they are tender and slightly charred. They can also be grilled, sautéed, or boiled, and are often cooked with onions, garlic, and chili peppers to add flavor and heat.
Once cooked, tomatillos can be used in a range of traditional Mexican dishes, including soups, stews, sauces, and salsas. One of the most famous dishes featuring tomatillos is the Mexican sauce known as “salsa verde,” which is made by cooking the fruit with onions, garlic, and chili peppers to create a spicy, slightly sweet condiment.

How can tomatillos be preserved and stored to extend their shelf life?
Tomatillos can be preserved and stored in a variety of ways to extend their shelf life. One of the simplest ways to preserve tomatillos is to dry them, either by air-drying or using a food dehydrator. Dried tomatillos can be stored for up to a year and can be rehydrated by soaking them in water or broth. Tomatillos can also be frozen, either whole or cooked, and can be stored in the freezer for up to 6 months. Another way to preserve tomatillos is to can them, either by using a water bath canner or a pressure canner. Canned tomatillos can be stored for up to 5 years and make a great addition to soups, stews, and sauces.
In addition to these methods, tomatillos can also be pickled or fermented to preserve them. Pickled tomatillos are made by soaking the fruit in a brine solution, while fermented tomatillos are made by allowing the fruit to break down naturally over time. Both of these methods can help to preserve the nutritional content and flavor of the tomatillos, while also creating a delicious and unique ingredient to add to a variety of dishes. When storing tomatillos, it’s a good idea to keep them away from direct sunlight and heat, as well as moisture, which can cause them to spoil. By using one or more of these preservation methods, cooks can enjoy tomatillos year-round and add their unique flavor and nutrition to a wide range of dishes.
Can tomatillos be grown at home and what are the basic requirements for cultivation?
Yes, tomatillos can be grown at home, either in a garden or in containers. The basic requirements for cultivation are full sun, well-draining soil, and a warm, frost-free climate. Tomatillos are a warm-season crop and thrive in temperatures between 65-85°F (18-30°C). They can be started from seed indoors 4-6 weeks before the last frost date, and then transplanted outside when the weather warms up. Tomatillos prefer a slightly acidic to neutral soil pH, and can benefit from regular fertilization and watering. They are also a good candidate for container gardening, and can thrive in large pots or planters with good drainage.
In terms of specific growing requirements, tomatillos need a trellis or cage to support their growth, as they can become quite large and sprawling. They also need to be kept consistently moist, but not waterlogged, as this can lead to disease and root rot. Tomatillos are also susceptible to pests like aphids, whiteflies, and hornworms, and may require regular pest management to ensure a healthy harvest. With proper care and attention, tomatillos can be a fun and rewarding crop to grow at home, and can provide a delicious and nutritious addition to a variety of dishes. By following these basic growing requirements, gardeners can enjoy a bountiful harvest of tomatillos and experience the unique flavor and nutrition of this fascinating fruit.
