Peel a carrot and a piece of daikon as big as two carrots with a vegetable peeler. Discard the outer skin, and then continue 'peeling' to obtain long thin orange and white vegetable 'ribbons'. As you work drop the carrot and daikon strips into a bowl filled with water and lemon juice. Let the vegetables soak for about 30 minutes. In the meantime toast a tbsp or so of sesame seeds in a hot frying pan, and then mush them lightly with a mortar and pestle (I have a Japanese one for this, but any mortar and pestle will do). Set aside. In a small bowl thin one tbsp of miso (white or red) with a little hot water, or hot vegetable stock, into the consistency of a salad dressing (i.e.: not too runny, but not as thick as to be impossible to fold into a salad). Add 1 tbsp of soy sauce too, if you like (or gluten free tamari sauce). Drain the vegetables and add the miso dressing. Mix and divide between 4 bowls (if eating immediately, otherwise store in the fridge, covered, it will acquire even more flavour!). Before serving top each bowl with a pinch of crushed toasted sesame seeds.
