Yep. so why would I want to add more?
Seriously though, I have no problem with people using additional improvers, but I don't - it's a pity we can't get an 'easy blend' (powdered) yeast without them - unless someone knows a source?
I have made my bread recipes with fresh, ordinary dried, and wild yeast and, other than the rising/proving times, there is no significant difference. I use easy blend because then my bread making fits easily into my life and I'm able to make all our bread this way. Whichever method you use the important thing is to have a routine you can maintain, otherwise it just becomes a chore.
