The stem is usually harvested at a length of around 15-20 cm and a diameter of around 3-4 cm. It is crisp, moist, and mildly flavored, and typically prepared by slicing and then stir frying with more strongly flavored ingredients.
Celtuce is a lettuce family originating from southern China. It is named after its unique combination of characteristics, the celery-like stalks and the lettuce-like leaves.
In China, the plant is grown mainly for the fat central stalk that is very crispy and tender. Young leaves can be used as lettuce for salads and stir-fry.
