Hi Al
Thanks for sharing your Bhaji recipe.
Interesting that you say the Zeera Restaurant technique, as I'm involved in Zeera, I'm curious to where you have taken your reference from i.e. which post or video.
Also interested in which TA in Sunderland did you use back in the 80's, as I was involved with the Melting Pot Group of BIR and TA's back then
the Moti Raj being their flagship Restaurant.
My early memories on Mushrooms, in the main, they used dried catering mushrooms, which were soaked in water to rehydrate.
Can't remember anybody using tinned mushrooms at all.
The chef at Zeera only uses fresh and has done since the restaurant opened.
On the oil front for the OP, at Zeera, clean fresh oil in the base and the curries.
cheers Chewy
