1, blanching: Blanch fresh lentil horns in boiling water. The blanching time should not be too long, usually 3 to 5 minutes. Blanching water can remove impurities and odor from lentil horn and make it easier to be frozen.
2. Freezing: Remove the blanched lentil horn, rinse it with cold water, and then dry the water. Put the dried lentil horn into a fresh-keeping bag, exhaust the air in the bag as much as possible and seal it, or put the lentil horn into a sealed box and freeze it in the freezer.
