Water roux method - ratio of roux to other flour
I've been wanting to try the water roux method for a bit now and have trolled around The Fresh Loaf and the internet to get an idea of the ratio of roux to flour but either I'm dense or no one says, for example: use 50 gm roux for a recipe containing 500 gm flour.
Is there an optimum ratio for the roux to the rest of the flour in any given recipe? 10% by weight, 20%?
Thanks,
Constance
