This recipe is a hybrid of sourdough and yeast, due to wanting the final fermentation with the 30% spelt included, to only be 90 minutes in duration.
This final loaf does not have any sour notes, which I personally do not favour, but has a deep nutty flavour, and is best suited to either toasting for breakfast, or naked with cheese. I find using a 1.6% of total flour as the salt ratio to be acceptable for my taste.
Check the fairly open crumb, and fairly thick crust, as I like it....
