What are Tomatillos?

Tomatillos are small, round, green fruits that are often used in Mexican and Central American cuisine. Along with potatoes, tomatoes, peppers, eggplant, and other members of the nightshade family, tomatillos (also known as husk tomatoes) are annual plants.

Although tomatillo plants are related to tomatoes, they don’t produce juicy fruit. Instead, tomatillos resemble unripe tomatoes in appearance and texture since they are small, spherical, hard, and have a packed interior.

Although some varieties of ripe tomatillos turn yellow or purple, they are typically bright green. The thin, papery husk that develops around the fruit to preserve it while it ripens makes them distinct from other fruits. As a result, they resemble cape gooseberries, often known as ground cherries or husk cherries.

They, however, will never become sweeter like ground cherries or tomatoes, no matter how ripe they become. Instead, they have a tangy, vibrant flavor that resembles limes in certain ways. Tomatillos lose their acidic edge and become a little bit sweeter when they are roasted.

What are Tomatillos?

Despite their name and appearance, tomatillos are not tomatoes but belong to the nightshade family, along with tomatoes, potatoes, and peppers. They have a papery husk that surrounds the fruit, which is typically removed before cooking.

Tomatillos have a tart and tangy flavor, adding a unique citrus-like taste to dishes. They are a staple ingredient in many traditional Mexican dishes, particularly in sauces and salsas. Commonly referred to as “tomatillo salsa” or “salsa verde,” these green sauces are made by blending or cooking them with other ingredients such as chili peppers, onions, garlic, and herbs.

When selecting them, choose ones that are firm, bright green, and have a dry, intact husk. Avoid those that are soft or have blemishes on their skin. They can be stored at room temperature for a few days or kept in the refrigerator for up to two weeks.

In addition to their culinary uses, tomatillos are also a source of various vitamins and minerals, including vitamin C, vitamin K, and potassium. They are low in calories and can be a nutritious addition to a balanced diet.

They are incredibly versatile and can be used in a wide range of recipes beyond salsas, such as soups, stews, enchiladas, and salads. Their tartness and distinctive flavor can add brightness and depth to many dishes, offering a unique twist to your culinary creations.

What Does Tomatillos Taste Like?

Tomatillos have a distinct flavor that is often described as tart, tangy, and slightly acidic. They have a unique taste that sets them apart from regular tomatoes. The tartness of tomatillos is reminiscent of citrus fruits, particularly green apples or sour green plums. Some people also detect a hint of sweetness underneath the tartness.

The flavor of tomatillos can vary depending on their level of ripeness. When they are fully ripe, they tend to have a slightly sweeter taste. However, the most commonly used tomatillos are picked when they are still firm and green, which contributes to their characteristic tanginess.

It’s important to note that the flavor of tomatillos can be influenced by how they are prepared and used in dishes. Cooking tomatillos can mellow out their tartness and bring out their natural sweetness.

When used in salsas, sauces, or cooked dishes, the tartness of tomatillos can provide a refreshing and bright flavor that pairs well with other ingredients.
