Daikon means big root, and boy do they grow big in Japan. I love going to the Japanese markets and seeing all the fresh produce there grown by local farmers.
Daikon has to be one of my favourite vegetables, although not originally native to Japan it is now Japan’s most widely cultivated vegetable. In season mainly from autumn to spring you can pretty much pick them up all year round in Japan. Daikon is good for the digestion and is such a versatile ingredients in cooking. I often manage to get mooli which is the most similar but they are never quite the same as the ones in Japan. Daikon has a light peppery flavour and when cooked in broth soaks up lots of flavour, I particularly like them in winter hot pot dishes. It can be eaten raw, simmered, fried, pickled and dried. Dried is known as kiriboshi daikon 切り干し大根 and this is what I will be using in this recipe. Kiriboshi translates to cut 切りand dry 干しin Japanese. It is basically daikon 大根 that has been shredded and traditionally left out to dry in the sun. Preserving daikon in this way has been popular since the Edo period ( 1603-1868). The daikon becomes sweeter when dried, packed with umami flavour. Drying also concentrates the fibre and mineral content making it a good source of calcium and iron.
This is normally how you will buy kiriboshi daikon. You may see the words Singiri ぜんざい written in Japanese on the packet this means julienne in English, vegetable cut into strips . This is what I will be using for the simple but tasty rice kiriboshi don ( rice bowl ).
First take a handful of the dried daikon and wash it in a sieve under running water. Then place in a bowl and add warm water, leave to rehydrate for around 15 mins. To make this dish I used Arame seaweed. This is a species of kelp and looks a little similar to Hijiki. It comes dried so you need to do the same to this as the kiriboshi wash and leave to rehydrate. Unlike the daikon when it is rehydrated you will need to simmer the Arame in boiling water for about 20 mins.
Now your daikon is rehydrated you will notice the liquid that it is in has turned yellow. Drain off the liquid but retain it in a jug squeezing any excess liquid out the daikon also into the jug placing your daikon in a bowl.When you have your Arame simmered and drained add this to your daikon in a bowl. Add to your bowl with the daikon and Arame, a tablespoon of mirin and a tablespoon of tamari. Leave while you prepare your rice. Take a rice cooker cup of sushi rice and wash it until the water runs clear. Add this to your rice cooker and add two cups of your daikon liquid, top up with extra water if needed. Then add the juice of fresh grated ginger I used about an inch piece and a small piece of kombu again only a few inches. Let this soak for around 20 mins and then remove the kombu. Put your rice cooker on cook and prepare your kiriboshi and Arame by sautéing in toasted sesame oil, I added some extra chopped negi ( green onion ) for a little colour.
When your rice is done spoon into a bowl and add your sautéed kiriboshi on top. Sprinkle with sesame seeds and if you have any ground black sesame salt. The rice has taken on the delicious flavour of the sweet daikon and ginger, it makes for a nutritious and filling meal that’s full of umami.
