Lightly toast the walnuts either in a frying pan over a gentle heat or under the grill.
Lift the bread pan out of the machine and fit the blade. Put the ingredients, except the walnuts, in the pan, following the order specified in the manual.
Fit the pan into the machine and close the lid. Set to a 750 g (1½ lb) loaf size on the wholemeal programme. Select your preferred crust setting. Add the walnuts when the machine beeps.
At the end of the programme lift the pan out of the machine and shake the bread out on to a wire rack to cool. Serve drizzled with extra honey.
