Learn how to make Hana Renkon, or flower-shaped lotus root. This Japanese cutting technique creates decorative slices of the root vegetable to use in the Osechi Ryori meal on Japanese New Year and other celebratory occasions.
Cut the lotus root crosswise into a 2-inch piece so it’s easy to work with. Next, carve out a V-shaped notch lengthwise between two holes along the length of the root.
Continue cutting lengthwise notches between the holes until you've cut around the entire outside of the root. The cross section of your lotus root should now resemble a flower.
Then, cut the root crosswise into ¼-inch (0.6-mm) slices.
Once you’ve sliced the lotus root, add the slices to a bowl of vinegared water (1 tsp rice vinegar and 2 cups water). Soak the lotus root slices for 5 minutes to prevent them from changing color and to remove the astringent taste. The hana renkon are now ready to use in your favorite recipe.
