90% Levain-biga ciabatta
A bit of an experimental ciabatta. I intended to make a 90% biga ciabatta but thought - what if I used a levain to make the biga, rather than my starter+water? The idea was that I could develop a more complex flavour profile by making a higher temp spelt-rye levain from my basic starter (5 hour fermentation, 22 degrees), and then use that to form the 45% hydration of the cool biga (16 hour fermentation, 14 degrees).
