I've been cooking curry's over 20 years, but only in the last couple of years did I get into base sauce. Amazing how you can knock up a curry so quick.
Lots of different chefs method's are very similar but very wordy, which tends to make them seem different and can have you lose focus on the main thread. While documenting, I try and keep things simple and put the rest of the "fluff" down to experience. This way I managed pull together 9 completely different curry recipes in 1.5 pages of A4. Essentially it's a super short, concise, ebook. Thought I'd share. Not sure if this is the best place for such a thing, but I see this thread as more about 'keeping it simple', using a standard approach, adapted slightly for each recipe, and less about the recipes themselves. Follow this standard approach, and take ideas out of other peoples recipes to try and match what you are looking for in your own curry.
CURRY METHOD
Pre-fry
6 tbs veg oil
1-2 tsp garlic & ginger paste
1-2 tbs fine chopped onion & green pepper
Fry above until just before browning.
Spice fry
1 tsp chilli powder
Spices
Add above and fry some seconds.
Main cook
1 portion base sauce
1 tsp salt
1 portion of pre-cooked meat
On high heat, add some base sauce bit by bit to prevent the spices burning. Add the salt. Add the meat. Reduce to simmer. Thicken the sauce to the desired consistency.
Late additions
Add the aromatics and other late additions and simmer for a minute or 2.

My favourites are the Jalfrazi & Sagwala, both made unique with the addition of their respective hard whole spice. Keeping my recipes written simple like this allows me to see easily what it is that contributes to the flavour of each curry, and so more easily pick out problem additions or omissions as I continue my search for perfection. My current base sauce of choice is Chewy's, which I split into 6 portions and cook with 400-500g meat.
