HI CA, what i mean is that a real bir recipe (base + a madras to go with it) must have been gradually developed over many years (possibly handed down through generations) this is why they are commercially viable, and taste much better than home cooked curry. I feel many recipies on this site are not as developed in comparison to this benchmark. I am not saying they are not good recipes, as they are very enjoyable. The chef at my local even clearly stated that you need to make tiny changes to recipies to improve it step by step, over many years. After many years it will develop in taste. Even an 8th of a tsp of tumeric can change a recipe final taste. For me thats part of the missing stages i am working on. I am trying to get to know all the key ingredients (spices, tomato, fesh coriander, garlic paste, tom puree etc) tiny chnages too the amounts of any one of these can make significant differences to the final curry. Its hard to give examples, as its best explained by just doing it yourself. I found that my madras was tasting strange when i added lemon. It turns out a year later that this was due partly to the safron base, and the tumeric in the spice mix. now i have a new base i am testing, and make a new spice mix, and the issue no longer occurs. for me it was a breakthrough. finally i got rid of a taste that had bugged me all year. its still not perfect, but much better. my new recipe still has some issues, but it will be fun working out how to fix them.
