ok, i found a recipe:
200g each of strong white / wholemeal flour (this is 50:50 bread, which is cool)
1tsp sugar, same of salt
300ml water
15g butter (or baking margarine)
select wholemeal program, wait 5 hours
the problem with that is that the breadmaker i'm looking at is rated 550W. 5 hours of that, as of July, is going to cost about 80p (obviously that might not be constant, but still) - that's for the electricity alone
ASDA sells an 800g loaf of wholemeal bread for 58p at the moment - now obviously that might go up soon too (their prices have been on the rise of late) but it's held there so far. so as far as i can see, a bread machine doesn't make any economic sense
