Chris has already invited CR0 members to join him for tuition, and one has already reported back that the day was a great success. I think he deserves recognition for that...
Why? What knowledge or information is he imparting into this forum? Nothing. He's taking out and putting nothing back.
The forum members who got all excited about their visit and cooking lesson at Zaal in Fleet all reported having a successful days cookery tuition and were kind enough to share their discoveries with the forum. What did they discover? Any new innovative ways of unlocking the taste to BIR Takeway's as Chris is claiming? No. They kindly described a recipe and instructions for cooking a base in a slightly different way using water to extract flavour from whole spices and frying spices in g/g before adding tomato and then adding to the base sauce. A different way of doing something, but not revealing anything anyone on here doesn't already know about. A variation on a theme. A slightly different way of doing something.
I've tried the Zaal base, made to spec and I think it's a good one. Did it change the way I cook bases? No. Did it fundamentally change my mind about how BIR bases are made? No. Did it teach me anything new? No.
Chris will not produce anything different but variations on a theme we already know about. Perhaps a difference sequence of cooking, perhaps a more streamlined way of cooking, perhaps changing ingredient ratios - but nothing fundamentally new, or that anyone on here doesn't already know about.
JB above suggests his methodology heavily relies on spiced oil, that's not new either, there's plenty of recipes for spiced oil on here and using reclaimed oil from cooked bases and dishes is widely known about and used.
What's so special about spiced oil? It's spice essential oils extracted and dissolved into an oil flavour carrier which is then used in the frying stage, added to base sauce or even added towards the end of cooking a dish. It just introduces another layer of flavour.
What's new? Nothing. CA gave recipe for spiced oil way back when...
Everything (the techniques and ingredients) anyone needs to cook and produce very BIR smelling and tasting dishes that will challenge their local takeway is right here on this site, right now if they want to look for it.
Yet Chris seems to think he's come up with some secret, unknown, not commonly used techniques for achieving that BIR taste and aroma we don't already know about? :

Not in my opinion.
