Cốm, or green rice, is a dish in Vietnamese cuisine. It is not dyed green, as can be done with pandan, but is immature rice kernels roasted over very low heat then pounded in a mortar and pestle until flattened. Cốm is seasonal dish associated with autumn. It can be eaten plain or with coconut. The taste is slightly sweet with a nutty flavor.
A traditional pastry, bánh cốm (green rice cake) is made using cốm with mung bean filling. Cốm is often offered to worship the ancestors in the Mid Autumn Festival. The green rice can also be used in sweet soup, chè cốm. Cốm is similar to flat green rice of the Khmer people.
