Peel the daikon thickly, cut it in half lengthwise, and slice thinly. Trim the pea shoots and cut them into 3cm pieces. Dice the firm tofu into 1.5cm cubes.

Boil water in a pot, add salt and tofu, and cook for about 2 minutes until the tofu floats. Remove and pat dry with kitchen paper. Re-boil the water, add daikon, and blanch briefly. Drain well.
