Understanding Cilantro: Selection and Storage Basics

Cilantro, also called coriander leaves or Chinese parsley, is a leafy green herb that comes from the coriander plant. The herb has a distinctive taste that people either love or dislike—studies show that approximately 4 to 14 percent of people perceive cilantro as tasting soapy due to a genetic variation in their taste receptors. Despite this polarizing flavor, cilantro remains one of the most widely used herbs in cuisines around the world, particularly in Latin American, Southeast Asian, and Indian cooking.

When selecting cilantro at the grocery store or farmers market, look for bunches with bright green leaves and firm stems. The leaves should not appear wilted, yellowed, or slimy. Fresh cilantro typically costs between $1 and $3 per bunch, depending on your location and the season. Spring and early summer represent peak cilantro season in most parts of North America, when the herb is most abundant and affordable.

Proper storage extends cilantro's shelf life from a few days to up to two weeks. Place the unwashed bunch in a glass of water, similar to how you would store fresh flowers, and cover the leaves loosely with a plastic bag. Store this arrangement in the refrigerator, changing the water every two to three days. Alternatively, you can wrap damp paper towels around the cilantro, place it in a plastic bag, and refrigerate it. Some people prefer freezing cilantro in ice cube trays with a small amount of water or olive oil for use in cooked dishes later.

Practical takeaway: Purchase cilantro with bright green leaves and firm stems, store it in water in the refrigerator with loose plastic covering, and change the water every few days to maintain freshness for up to two weeks.

Washing and Drying Cilantro Properly

Washing cilantro removes dirt, debris, and any pesticide residue before you incorporate it into your dishes. Because cilantro has delicate leaves and grows in bunches, washing requires a gentle approach to avoid bruising or damaging the herb. Start by filling a bowl or sink with cool water—cold water is preferable to warm water because it helps keep the herb crisp and maintains its vibrant color.

Submerge the entire cilantro bunch in the water and gently swish it around for about 30 seconds. Pay particular attention to the areas between the leaves where dirt often accumulates. If the cilantro appears particularly dirty, you can repeat this process with fresh water. Some people prefer to hold the bunch under running water while gently rubbing the leaves with their fingers, but this method requires careful handling to avoid crushing the delicate foliage.

After washing, proper drying prevents moisture from causing the herb to wilt or develop mold. Pat the cilantro gently with clean paper towels or a soft cloth, being careful not to compress the leaves. For a more thorough drying, place the washed cilantro in a salad spinner—a kitchen tool that removes water through centrifugal force. Spin the herb for about 30 seconds, then allow it to sit in the spinner for another minute or two to release any remaining moisture. If you don't have a salad spinner, you can wrap the cilantro loosely in paper towels and let it air dry for 15 to 20 minutes before using it.

Practical takeaway: Wash cilantro by submerging it in cool water and gently swishing, then dry it using a salad spinner or by patting with paper towels to prevent bruising and remove excess moisture.

Separating Leaves from Stems and Deciding What to Use

Cilantro consists of two distinct parts: the delicate leaves and the more fibrous stems. The flavor and texture of each part differ, and knowing how to separate and use them helps you get the most from your herb. Many recipes specify using only the cilantro leaves because they have a more intense flavor and a tender texture that works well in raw applications like salsas, guacamole, and garnishes. The stems, however, have a milder flavor and tougher texture, making them better suited for cooked dishes, soups, and curries where they can soften during cooking.

To separate leaves from stems, hold the cilantro bunch by the base and, working from the bottom upward, pinch the stem between your thumb and forefinger. Slide your fingers upward along the stem—the leaves will naturally separate and fall away. This method works efficiently for large quantities and typically takes only a few minutes to process an entire bunch. If you have only a small amount of cilantro or prefer a different approach, you can simply pluck individual leaves by hand, pulling them gently away from the stem.

The stems are not wasted material. Thinner stems near the top of the bunch remain relatively tender and can be chopped finely and included with the leaves in cooked dishes. Thicker, woodier stems from the base of the bunch work well in stocks, broths, and infusions where they contribute flavor while the liquid is simmered. Some cooks save cilantro stems in the freezer specifically to add to vegetable stock. Studies on herb waste show that using the entire plant—stems included—reduces food waste and maximizes the nutritional value you obtain from the herb.

Practical takeaway: Separate cilantro leaves from stems by pinching and sliding your fingers upward; use tender leaves for raw dishes and garnishes, reserve tender stems for cooked applications, and save woody stems for stocks and broths.

Chopping and Mincing Cilantro for Different Cooking Methods

The size to which you chop cilantro depends on how you plan to use it. For dishes where cilantro serves as a garnish or primary ingredient, like salsa or chimichurri sauce, coarse chopping works well—roughly breaking the leaves into pieces about one-quarter to one-half inch in size. This allows the cilantro flavor to stand out while maintaining some visual texture in the dish. For applications where you want cilantro to blend more seamlessly into the dish, such as in soups or curry pastes, mincing the herb into very small pieces, typically about one-eighth inch or smaller, helps distribute the flavor throughout.

To chop cilantro, place the washed and dried leaves on a clean cutting board. Gather them into a loose pile and, using a sharp chef's knife or other cutting implement, rock the blade back and forth over the herbs, periodically gathering them back into a pile. Continue until the cilantro reaches your desired size. A sharp knife is important because a dull blade tends to crush the delicate leaves rather than cut them cleanly, which can cause browning and flavor loss. One bunch of cilantro, weighing approximately one-quarter pound or about 113 grams, yields roughly one-half cup of loosely packed chopped leaves.

Some recipes call for minced cilantro, which is finer than chopped. For mincing, start by chopping the cilantro into roughly one-eighth inch pieces, then continue chopping with a rocking motion until the pieces become very small and fine. This technique works particularly well with a sharp knife and a cutting board, though some people prefer using kitchen shears or a food processor for mincing larger quantities. If using a food processor, pulse the cilantro rather than running the blade continuously, as extended processing can bruise the leaves and cause them to release too much liquid, resulting in a paste.

Practical takeaway: Use coarse chopping (one-quarter to one-half inch pieces) for garnishes and salsas, mincing (one-eighth inch or smaller) for blended applications, and always use a sharp knife to cut rather than crush the delicate leaves.

Cooking with Cilantro: Heat Exposure and Timing

Cilantro's flavor profile changes significantly depending on how much heat exposure it receives. Fresh, raw cilantro delivers a bright, clean, slightly citrusy taste that works well in uncooked applications. When cilantro is exposed to heat for extended periods, its flavor becomes more muted and subtle, which some cooks view as a loss of the herb's distinctive character. For this reason, cilantro is most commonly added at the end of cooking or used as a raw garnish. However, understanding how to use cilantro throughout the cooking process allows you to create layered flavors in your dishes.
