Hi Adrian, thats the kind of approach the chef at my local spouted on about one night. i like the sound of that chicken stock, it certainly adds a lot of taste. the head chef also said its good to simmer whole spices in water. he did not say what you do with the water though. i tried adding some flavored spicy water to the base, and it was unclear if it was a step forward. he also mentioned the importnace of cooking whole spices properly to remove the raw taste. i guess they might use whole spices in some dishes, once they have been pre cooked to remove raw taste. not sure? i intend to try pre cooking cloves in water, then mash them up and add a little to a jalfrezzi.
