[Sca-cooks] Period Flour Query

[Terry Decker]

Bolting or boulting is done by sieving meal through progressively finer 
weaves of cloth which regulate the fineness of the flour, as you suggest. 
Bolting clothes were commonly linen, but canvas and silk have also been used 
and they weren't standardized.  Today we use wire mesh in the sieving 
process.

Whether the cloths were stretched on frames or not, I don't know.  From a 
little experimentation, I don't think they would have been stretched taut as 
meal would have been bouncing over the sides.

While there was no regulation on flour, IIRC, the highest quality bread, and 
therefore the most expensive, was required to be made from thrice bolted 
flour.  Since I am unsure in my memory, check the assize of bread if you 
plan to quote me.
