To keep the angelica in the refrigerator, wrap the whole plant in damp absorbent paper and place it in a perforated plastic bag. Keep it in the refrigerator for about a week. You can also freeze the angelica. Wash it carefully, dry it and cut it into small pieces. Place them in a freezing bag, press the air and seal it. You can then keep the sachets in the freezer for several months. This method works well for the angelic. Wash the plant and dry it thoroughly. Tie it into small boots and hang it backwards in a dry and well ventilated place. Once the stems are dry and brittle, remove the leaves and stems and store them in an airtight container. Angelique can also be kept in sugar. Wash the plant and dry it thoroughly. Cut the stems into small pieces and place them in a jar, alternating the sugar and angelic layers. Hermetically close the jar and store it in a cool and dry place.
