This is something my kids love to do. Mostly we just use the bread machine, as kneading bread dough is a lot of work, but the final shaping is done by hand because I don’t like the shape of loaf that my machine makes.
To me this is somewhat better than free, once you have a bread machine. You’ll save money on bread and know exactly what you put into it. Bread has gone up in price in the past year or so. Homemade bread can be very cheap to make.
It can even be something of a science experiment. Yeast can be interesting to watch grow over a few hours. You can make your own starter for sourdough… although that takes a number of days. It’s easy to get the kids involved in checking on and feeding the starter. I wouldn’t suggest having it replace the family pet, of course.
Don’t forget the delightful smell of bread baking. It’s a great way to make the house smell wonderful too.
