Welcome cf7 I'm in Geordieland by the Sea.
Quite a difficult one to help with really, if Scree Krishna has kitchen staff from Kerala and cooking in a South Indian style.
Most peoples experience here, is with Bangladeshi staff, cooking for the English palate.
In saying that, I met and was talking to a new Tandoori chef here, who's worked all over London.
Interestingly, he said a lot of Pakistani or other regional Indian restaurants, employ Bangla curry chefs.
So if you make a Bangladeshi neutral base (Garabi) and hit it up with South Indian flavours and ingredients
you may be lucky and get somewhere close to what your looking for.
If your already a traditional curry cook, you'll know your prep and spices, so it should be easy for you
to switch to quick fry curries using a base gravy and precooked meats and veg.
You could start off with my quick Garabi and a Madras, just to get in the swing.
