Yes, thanks Cory A, well done in sorting that out. Size doesn't really matter, I know from years of experience :-[. Its the ratios of the ingredients that are important and it is not proportional either, i.e. if you use a 7 litre pot instead of a 14 litre pot you don't just halve the quantities!
I am not sure whether the amount of onion is relevant either, as it eventually is only bulk with little flavour; the acids and thus the flavour is mainly lost in steam. I always have a simple onion base alongside my UCB so that I can get blends and sauce consistency right.
Wishing you success
