Corn salad, a leafy green vegetable, has a long history in Europe but is becoming increasingly popular globally. It offers a delicate texture and a fresh flavor profile. While often overshadowed by more common salad greens, its ability to thrive in cooler temperatures makes it a valuable crop, especially during the colder months.
Defining the Corn Salad Plant
The corn salad plant is scientifically classified as Valerianella locusta, an annual flowering herb belonging to the family Caprifoliaceae. It is known by several common names, including Lamb’s Lettuce, Fetticus, Field Salad, and Mâche. The name “corn salad” originated from the plant’s tendency to grow as a weed in European grain fields, where “corn” was a general term for cereal crops.
The plant is native to Europe, Western Asia, and North Africa, where it has been cultivated for centuries. Its physical appearance is characterized by small, spoon-shaped leaves that grow in a low-lying rosette pattern, reaching up to 15 centimeters in height. Due to its hardiness, it is cultivated as a winter green in many mild climates.
Flavor, Texture, and Nutritional Profile
Corn salad has a mild, slightly sweet flavor, often described as having subtle nutty notes. Unlike some other salad greens, its taste is not bitter or strongly herbal, allowing it to pair well with a variety of dressings and ingredients. The leaves possess a tender and delicate texture, giving a smooth, almost buttery mouthfeel when eaten.
It is typically eaten raw in simple salads where its delicate nature can be appreciated, and it holds up well to light vinaigrettes. Corn salad is a nutrient-dense food, being low in calories and high in water content. A serving provides a good source of several micronutrients, including Vitamin C, Vitamin A for eye health, and folate, a B vitamin important for cell division. The leaves also contribute iron and potassium.
Cultivating and Harvesting Mâche
Mâche is a cool-season crop, demonstrating high cold tolerance that makes it suitable for late fall, winter, and early spring harvests. It can withstand temperatures as low as -15°C (5°F) without protection. For germination, the soil temperature must remain cool, ideally between 10°C and 21°C (50°F and 70°F), as warmer temperatures can cause the seeds to become dormant.
The plant thrives best in rich, well-draining soil that has been amended with compost or organic matter. It can tolerate a range of light conditions, appreciating full sun in the cooler months and partial shade as temperatures begin to rise. When harvesting, the entire rosette can be cut at the base. Alternatively, to prolong the harvest, the larger outer leaves can be taken while leaving the inner rosette intact. Harvest must occur before the plant begins to flower and set seed (bolting), which makes the leaves unpalatable.
