I have found a difference between between boiling onions and frying them.  I have found when boiled in water they taste stewed and ruin the taste somewhat but extended frying gives a lovely flavour and sweetness that is associated with BIRs.

Thanks naga Dave, I thought as much.

Hi Haldi, Ive heard about this book and the recipes are supposed to be from 1960s BIR in Glasgow.  Is it any good and have you tried making any of the recipes yet?

Just wondering how this would be made on a large scale in a BIR?

Its the best Ive tried also Mike, it's going to take some beating for it's BIR authenticity.

Sounds nice Mike, I gave Curry Kings Bhuna recipe a go using Admins new bas and it was fantastic.

This is a link to the Rick Stein curry recipe that Admin mentioned concerning this new base.  It claims to be the only curry recipe you will ever need.

I wonder who will try this base first?

Hi Handbag and welcome, try this base from the link below, you wont be disappointed.

Lorrydoo.

Hi Richard, I personally prefer a hand blender because you can blend without adding air to the base (if you keep it submerged in the sauce at all times then it doesn't suck any air in).
