广东 芥兰 要选比较鲜嫩的，最好是拇指大小的，越均匀越好。

之所以说要广东 芥兰 ，原因也在这里。

目前很多菜市场、超市的 芥兰 都是本地产的，不是说这样的不好吃，但相对来说，还是大颗的广东芥兰更地道些。

推荐去东郊批发市场购买，那里都是为酒店供应蔬菜的，可以说是货真价实。

芥兰 含丰富的维生素a、c、钙、蛋白质、脂肪和植物醣类。

有润肠去热气，下虚火，止牙龈出血的功效。但有一点，不能一次吃太多哦，也不能太频繁地吃，据说可以杀精。

Guangdong mustard greens should be chosen to be relatively fresh and tender, preferably thumb sized, the more even the better. The reason why we want Guangdong mustard is also here. At present, many vegetable markets and supermarkets use locally produced mustard greens. It's not that they don't taste good, but relatively speaking, larger Guangdong mustard greens are more authentic. I recommend purchasing at the Dongjiao Wholesale Market, where vegetables are supplied to hotels at a genuine price. Mustard greens are rich in vitamins A, C, calcium, protein, fat, and plant carbohydrates. It has the effects of moistening the intestines, removing heat, reducing internal heat, and stopping gum bleeding. But one thing, you can't eat too much at once, and you can't eat too frequently. It's said to kill sperm.
