Chrysanthemum leaves is called 茼蒿 (tong gao) in Mandarin, Dang Oh in Teochew and Hokkien.
Chrysanthemum is better known for its flower tea. Chrysanthemum tea is an infusion of the petals of a certain type of chrysanthemum flower. It has a cooling effect and is mild enough for children. The tea is drank but the petals are not eaten.
There is a part of the chrysanthemum that is edible: the leaves of the garland chrysanthemum. Note that not all types of chrysanthemum leaves are edible, just garland as the leaves are tender.
My grandmother always have it for the Chinese New Year hot pot. It is supposed to represent something but I cannot remember. It is a Teochew tradition. It is an acquired taste because the leaves are slightly bitter. You know what the old folks say, bitter is good for health. Grandmother loves it because whenever she talks about it, her eyes shines. What is it with old people and bitter food?
Besides hot pot, it can also be added to quick soups. It cooks quite fast, so a quick short boil will do. In fact, it can be added to the soup after the heat has already been turned down and allow to steep.
The Japanese also uses the leaves in tempura. The bitterness disappears when the leaves are dipped in tempura batter and lightly fried.
How to prepare chrysanthemum leaves
Chrysanthemum leaves come in small bunches. There is no need to cut them up. Remove the roots and wash thoroughly to get rid of dirt. Cook them as it is. Like spinach, they can shrink considerably after cooking.
