To my mind, cooking (at least repeatability in cooking) is a science and a process, not an art form. It's all about understanding and controlling variables and reproducibility.
Artistry plays a part in recipe creation and dish presentation, but not in reproducing established recipes and procedures in a controlled manner.
That said, I respectfully ask that BB1 please confirms the size of his "chef's spoons" and whether the measures are level, rounded or heaped.
Clearly this is significant and important (and maybe more so than batch size) in being able to successfully recreate this base. My "chef's spoon (level) is 40ml.
Once BB1 has confirmed that, I will be happy to make and assess a full scale batch of this base and compare it with a small scale (scaled) version and others.
Until BB1 confirms the size of a chef's spoon and whether it's level, rounded or heaped, I believe that trying to reproduce it is erroneous.
PS: I presume that this is from a Punjabi owned (rather than a Bangladeshi owned) restaurant BB1? Either way, that's a lot for posting; looks sufficiently different to be interesting and worth trying

Cheers,
