Step-by-step

  1. Preheat the oven to 180°C/350°F/gas mark 4. Grease and line a 33x23cm (13x9in) Swiss roll tin with non-stick baking paper. Dust with a half-and-half mixture of caster sugar and flour.
  2. Mix the flour with the green tea powder and sift 2–3 times.
  3. Put the eggs and sugar in a bowl, place over a pan of simmering water and whisk, using an electric hand whisk, until pale, creamy and thick enough to leave a trail on the surface when the whisk is lifted.
  4. Remove the egg mixture from the heat, then sift half the green tea-flour mixture over and gently fold in with a metal spoon. Repeat with the remaining green tea-flour mixture, then lightly stir in 1 tablespoon of hot water.
  5. Pour the mixture into the prepared tin, then tilt the tin backwards and forwards to spread the mixture evenly. Bake for 10–12 minutes, until well risen and firm to the touch.
  6. Meanwhile, place a large sheet of greaseproof paper on top of a clean, damp tea towel. Dredge the paper thickly with caster sugar.
  7. Working quickly, turn out the sponge on to the paper, trim off the crusty edges and let it cool down.
  8. While the cake is cooling down, whisk the cream until soft peaks form. Spread the cream over the cake and make a line of adzuki bean paste along the long edge nearest to you.
  9. Roll up the cake, starting from the long edge with the paste on, with the aid of the paper. Make the first turn firmly so that the whole cake will roll evenly and have a good shape when finished, but roll more lightly after the first turn.
  10.  Place the cake, seam-side down, on a chopping board, dust with icing sugar, then slice and serve.
