Cooking Japanese is not necessarily difficult and it can be really quick. In winter I love daikon cooked in konbu (kelp) dashi and served with white miso, but this is not a whole meal so I prepared also in the same dashi some warm thick fried tofu served with little raw spinach and for the energy a bowl of rice mixed with 16 types of beans and seeds.
Prepare a konbu dashi with a piece of konbu in 1l of water, bring to boil and keep under cover. Cut 2-3cm high slices of daikon, one pr person is usually good, and cook them in the dashi. Check with a toothpick and remove them when soft. Serve in a bowl with one tsp of white miso on top. In the dashi still heated, add the thick fried tofu (atsu-age 厚揚げ) and cook for 5min, it washes away the oil from the deep fry. If you cannot find thick deep fried tofu you can warm momen (hard) tofu. When warm serve with baby spinach and a bit of soya sauce or a bit of ponzu sauce, or just a bit of the warm dashi. For the rice, I use a mix of seeds and beans that can be found in any organic supermarket or similar (if you cannot find some leave a comment I can help providing with some). That’s it. Keep warm and have a good weekend!
