I bake this every week.
It is a very basic recipe. I buy flour from Lidl (strong white / strong wholemeal).
750g wholemeal flour
250g white flour
2 teaspoons of dried yeast (superfine variety can be added as a dry ingredient)
2 teaspoons of salt
About 630g of warm water - varies between about 630g and 640g.
Mix dry ingredients. The white flour seems to make the bread rise much more easily. You can make it with 1kg wholemeal if you prefer.
Add the water - use weight rather than volume, as it is more accurate.
Knead for 10 mins or so.
Line the mixing bowl with a tablespoon or so of oil. Return the dough to the bowl, cover with a damp teatowel.
Put in the oven at 40°C for 90 minutes or until risen
Remove dough, divide into loaves, buns whatever, finalise the shape, place on baking sheets.
Add (toasted) seeds to the outside if you like
Leave at 40°C for 30-40 minutes (don't over-prove or it will sink)
Warm oven to 220°C
Bung the bread in for 7 minutes (120g buns) plus 2 or three, depending on how well you like it done, or for around 12 minutes (450g loaves)
