Mesclun, or mesclun greens, refers to a mixture of young lettuces. It’s the basic mix of greens in your local salad bar, on a menu at a restaurant, and in the produce aisle at the grocery store. The percentage of each leaf varies based on whoever has created the blend, but it’s always composed of the most tender leaves.
Mesclun is a mix of greens that are still young. In addition to lettuce, it might have things like spinach, savoury chicory, and sometimes even edible flowers.
