After all that .....Well, internet said 3 times weight so I just threw 21 grams in without premixing with water and it over rose quite a bit (about 20-30 percent more than usual, I do a 3 quarter size loaf and it almost came out of the tin) and finished with a floppy top. In fact I think it was the over rising that was also responsible for ripping the paddle off. Luckily I noticed it vibrating away and knocked back the dough by hand, but probably not enough as it still finished badly.
And my breadmaker probably doesn't make the best bread in the world but it makes a particular bread (made with milk) that my kids gobble up like no other and fits my cutting guide perfectly so it can be sliced and frozen in measured amounts. I've lost three stone this year and if I start making artisan bloomers I'll put it all back on and have nothing to feed the kids.
I'm assuming the premixing is the same for milk as water? Maybe don't need to add flour as milk has sugars anyway.
I'm tempted to try and make beer with the leftover yeast. I wonder if I really need a demi john or if it can just be done in 2l fizzy drink bottles.
... I've corrected the above for you
Actually I don't really recommend beer-making at home -- brewers and home-brewers have warned me about the amount of hard work involved what with all the sterilizing etc., and getting the yeast strain right can be pretty tricky, apparantly.
