Cilantro is the fresh leaf of the coriander plant, an aromatic herb with a bright citrus-green taste. The seeds of the same plant are usually called coriander and used as a spice, while cilantro refers to the leafy part. This matters in recipes: leaves and seeds give completely different aromas.
Cilantro is common in Caucasian, Mexican, Indian, Thai, Vietnamese, and Middle Eastern cooking. It is added to salads, salsa, soups, meat, fish, eggs, sauces, marinades, avocado dishes, and fermented vegetables. In keto and LCHF it is convenient because it brings a lot of flavor with almost no carbohydrate load.
Nutrition
In 100 g of fresh cilantro there are usually about 23 kcal, around 2 g of protein, about 0.5 g of fat, and about 3.5-4 g of carbohydrates, much of which is fiber. But 100 g of cilantro is a very large culinary portion. In practice, a few sprigs, a handful, or a couple of tablespoons of chopped herbs are used.
The leaves contain vitamin K, carotenoids, vitamin C, potassium, calcium, magnesium, and iron in small amounts. Cilantro, however, should not be treated as a mineral supplement. Its main role is aroma, freshness, mild bitterness, citrus note, and the ability to brighten fatty dishes.
The glycemic load of a usual serving is very low. Cilantro is therefore usually not counted separately in keto recipes when it is used as fresh herb rather than in a sweet sauce or ready-made seasoning with sugar.
Keto and LCHF use
Fresh cilantro fits keto and LCHF well. It pairs with meat, poultry, fish, seafood, eggs, avocado, cucumbers, tomatoes in a moderate portion, cheeses, sour cream, sugar-free yogurt sauces, olive oil, and hot spices.
Cilantro works especially well where the dish is fatty or dense: lamb, beef, pork, chicken thighs, oily fish, guacamole, creamy sauces, and coconut curry. Lemon or lime acidity, chili, and salt make the herb aroma cleaner.
How to use it
Cilantro is best added at the end of cooking or at serving. Long heating makes the leaves dark, soft, and less aromatic. The stems are edible too: they are juicier and stronger in flavor, so they can be finely chopped into sauces, marinades, and salsa.
For a keto sauce, cilantro can be blended with olive oil, lime, garlic, chili, salt, and avocado or sour cream. This sauce suits fish, chicken, eggs, fried cheese, salads, and grilled vegetables. In soups, cilantro is better added to the bowl rather than boiled in the pot.
If cilantro tastes soapy, this may be an individual perception of its aroma. In that case, using more cilantro will not help; parsley, mint, basil, or green onion will be better depending on the dish.
How to choose
Fresh cilantro should be springy and green, without slime, yellow leaves, or sour smell. Slight wilting can be corrected with cold water, but wet dark herbs with an unpleasant smell should not be used. Roots, when present, can be aromatic and useful in pastes and broths.
It is better to buy a small bunch and use it quickly. Chopped packaged herbs are convenient but lose aroma faster. Dried cilantro is not a true replacement for fresh leaves: the aroma becomes weaker and rougher, so bright sauces are better made with fresh herbs.
Limits
Allergy to cilantro is uncommon but possible, especially in people reacting to plants from the Apiaceae family. Because of vitamin K, people using warfarin need consistency in green herbs: cilantro does not always need to be excluded, but the amount should not change sharply.
Cilantro spoils quickly when stored wet and warm. Spoiled herbs can ruin a whole sauce or salad, so smell and texture should be checked before use.
Storage and substitutes
A bunch of cilantro can be placed stem-down in a glass of water, covered with a bag, and refrigerated. Another option is wrapping dry herbs in a paper towel and keeping them in a container. It is better to wash cilantro before use, not in advance.
Cilantro should be replaced according to the task. Parsley works for freshness, mint and basil for Thai and Vietnamese dishes, green onion and lime for hot sauce, and a mix of parsley, dill, and a little mint for Caucasian dishes. Coriander seeds are not a direct replacement for leaves: they bring warm spice, not fresh greenery.
