Google has let me down so I'm appealing to you lovely lot for help.
Many many years ago I found a recipe online in the Herts and Essex Observer for a chicken bhuna it was titled something like mums chicken bhuna and went something along the lines of cooking onions for ages so that they were a really rich brown colour, adding garlic then even more garlic, I imagine ginger was also involved, then it was various dry spices like coriander, cumin, chilli powder water was then added and cooked down before the chicken was added and a splash more water if required the final steps where adding garam masala and natural but not fat free as to watery yoghurt.
The link to the page has long since stopped working and I've changed my phone so can't find the document I had with it on but I love this recipe as it doesn't contain tomatoes and I can't seem to find a recipe that replicates it so far on Google and I can't remember it well enough to cook from memory.
I'll be eternally grateful to anyone who finds it.
