I always love lotus root for its beautiful natural design. The pale brown stem may look just like any other plant roots and characterless from the outside, but when you slice it open, the root reveals uneven tiny holes that are ready to surprise and delight. When sliced thinly, they even resemble delicate flowers. Lotus root also has an incredibly unique texture because even after cooking, it retains its crunchiness while staying tender. Today I’m going to share Pickled Lotus Root recipe, or we call Su Renkon (酢れんこん) in Japanese.
What is Pickled Lotus Root (Su Renkon)?
Su Renkon (酢れんこん) is a pickled dish where sliced lotus roots are marinated in rice vinegar, sugar, salt, mirin, and red chili pepper. With a refreshing and piquant taste, this vinegared dish is great as a palette cleanser between heavily seasoned foods. Because lotus root can oxidize after it is exposed to the air, we typically submerge it in the water with a little bit of vinegar or pickled in a vinegared sauce. This helps to remove any astringent taste and prevent the root from turning brown. This dish is eaten all year round, but it is specially served as one of the Osechi Ryori, a Japanese New Year Food.
Pickled Lotus Root (Su Renkon) as Auspicious Food
Lotus root has been considered an auspicious food for the Japanese New Year because lotus root with its many holes is a symbol of an unobstructed view of the future. It also has many seeds, hence it’s been eaten to pray for the prosperity of descendants.
Optional – How to Make Flower Lotus Root (Hana Renkon)
You might be curious how we make this pretty flower pattern out of lotus root. It’s actually not so difficult, but you will need:
Patience A very sharp paring knife Lotus root with even size holes
1. Cut lotus root into a 2-inch length so it’s easy to work with. Cut out the “V” shape between two holes.
2. Remove the v-shape part and continue to next area between the holes.
3. Now ready to cut into slices.
4. Slice into roughly 1/8 to 1/4 inch thick pieces.
Having a sharp knife helps you score the “V” shape and remove the excess part nicely. If you make a mistake, it’s okay. Move on to the next. Practice makes perfect.
