French baking - flour

Now I took the time to look through some shops to find flour type 812. It is really hard to find. They also don't put these type numbers on all flours. However, today then, finally, I found a shop that has this type 812 flour. By the way, the flour type 812 is spelt flour. Then I can try thre recipe in the book as it is written - I only need to find time again for this. After all I also need to prepare something going with the bread. On top of it I also still have some baguette I bought from the shop.
