I remember once buying bitter gourd, and the refrigerator couldn't put it on the floor. My kitchen is paved with 30 cm long floor tiles, and bitter gourd is shorter than the floor tiles (one end is against the wall). When I got up the next day, I found that the bitter gourd in the kitchen was yellow, which was a little longer than my floor tile. As a result, I dare not eat or throw. You can understand that bananas and fruits can be ripened, but they can also be peeled and eaten. You still need to add this fruit and vegetable, or you need it. It's not just Sanlu.
Look at your Shanghai green from the picture. I don't know if it's the light or the reason. The color is a little yellow, as if it is ripening. It should not be caused by pesticides, otherwise there should be a lot of pesticides in Shanghai.
Shanghai green leaf handle, the outside should be innocent, the center inside should be pure white, just pay attention next time.
