I think the best way is just to simmer in some base gravy for 20 mins whilst doing other prep. Enhances the base as well
Ed
Enhancing the base with chicken stock(made from bones /carcass)
& vegetable stock from pre cooked veg is a widespread restaurant(not curry forum)method also ed.
You can imagine why it's an aspect that's not publicised in web videos. There's no labelling either.
I love it though & couldn't give a monkey's tbh
