Shadow benny is a tropical herb widely used in Caribbean, Latin American, and Southeast Asian cooking. Its scientific name is Eryngium foetidum, and it goes by many other names depending on the region: culantro, recao, long coriander, sawtooth herb, and Mexican coriander. The flat, serrated leaves have a flavor similar to cilantro but noticeably stronger, which makes it a staple seasoning in Trinidad, Puerto Rico, Thailand, and beyond.
Shadow Benny vs. Cilantro
Shadow benny and cilantro are related (both belong to the same plant family) but they look and behave quite differently. Cilantro has delicate, rounded, feathery leaves on thin stems. Shadow benny has long, tough, blade-like leaves with serrated edges, growing in a rosette close to the ground. The leaves can reach 6 to 12 inches in length, making them easy to distinguish at a glance.
Flavor is where the two overlap. Shadow benny tastes like a more intense, pungent version of cilantro. A single leaf of shadow benny can replace a generous handful of cilantro in a recipe. This concentrated flavor is one reason Caribbean and Latin American cooks prefer it for long-cooked dishes: it holds up to heat far better than cilantro, which turns bitter and loses its punch when cooked for more than a few minutes.
How It’s Used in Cooking
In Trinidad and Tobago, shadow benny is essential to green seasoning, a fresh herb paste blended with garlic, thyme, scotch bonnet peppers, and other aromatics. This paste is rubbed into meats, poultry, and fish as a marinade, sometimes days before cooking. Shadow benny also appears in chutneys, soups, and stews across the Caribbean.
In Puerto Rico, where the herb is called recao, it’s a key ingredient in sofrito and is used in rice dishes, beans, and sancocho. In Southeast Asian cooking, particularly in Thailand, Vietnam, and Malaysia, the herb is added raw to salads, pho, and curries. The leaves are sturdy enough to be chopped coarsely and stirred in at the end of cooking without wilting into nothing.
Because shadow benny’s flavor is so concentrated, start with less than you think you need. One or two leaves, finely chopped, is often enough for an entire pot of soup or a batch of marinade.
Nutritional Profile
Shadow benny is rich in calcium, iron, and vitamins A and C relative to its weight. It also contains carotene and riboflavin. Traditional herbal medicine in the Caribbean and parts of Central America has long used shadow benny teas or infusions for digestive complaints, fevers, and inflammation. While formal clinical research on these uses remains limited, the herb’s antioxidant content is well documented.
Growing Shadow Benny
Shadow benny thrives in warm, humid climates and actually prefers partial shade, which is unusual for culinary herbs. It does poorly in direct, intense sunlight and bolts quickly in hot, dry conditions. This shade preference is likely the origin of its common name in Trinidad.
The plant grows well in moist, rich soil and can be cultivated in pots indoors or in shaded garden beds. It’s a biennial, meaning it completes its life cycle over two years, sending up a tall flower stalk in its second year before going to seed. To keep leaves tender and productive, many gardeners pinch off the flower stalk as soon as it appears. Seeds are slow to germinate, sometimes taking two to three weeks, so patience is needed when starting from scratch. In tropical climates, shadow benny often self-seeds and spreads readily once established.
Where to Find It
If you live near Caribbean, Latin American, or Asian grocery stores, you’ll likely find fresh shadow benny sold in bunches, sometimes labeled as culantro or recao. It’s less common in mainstream supermarkets in the U.S. and U.K., though availability has been increasing. The leaves freeze well: chop them, pack them into ice cube trays with a little water or oil, and freeze for easy use in cooked dishes. Dried shadow benny is also available but loses much of its aromatic punch. For the best flavor, fresh or frozen is the way to go.
