Just tear off all the layers on the surface of the chicken head stalk.

The cock-headed terrier is a kind of thorny terrier.

Euryale ferox, that is, chicken head rice, is an aquatic plant that grows in freshwater lakes. Its leaves look like lotus leaves, floating on the water like futon. The round leaves are turquoise on the front, purple on the back, and slightly upturned. "Compendium of Materia Medica" records: "In March, the stems are tender, the leaves are bigger than the lotus leaves, and the wrinkles are like boiling ... The flowers on the top of the buds are like chicken beaks and hedgehog beaks." But unlike the lotus leaf, the leaves and stems of Celosia cristata are covered with spikes, which may be pricked if you are not careful.

It is precisely because the leaves and stems of Celosia cristata are covered with thorns that it is not easy to pick the stems of Celosia cristata. First of all, because it grows in water, it needs to wear long-sleeved trousers and pick it in the water; Secondly, the thorn on the surface of the chicken head stalk is very stinging, so you need to wear gloves, otherwise you will be stabbed by it. Experienced pickers usually wear diving suits, thick plastic gloves and are armed to pick chicken heads.

Moreover, the stems of the picked Celosia cristata are covered with thorns and need to be peeled manually before they can be listed as vegetables. This is a repetitive work that requires patience. Every cockscomb stem must be peeled, otherwise it can't be sold. At present, the chicken-headed stalks sold in the market are all naked, so it is estimated that many people don't know the original ecological appearance of the barbed chicken-headed stalks.
