Steve/Frank,
appreciate your thoughts.
i feel i'm going to have to put tarragon on my to do list. i'll ask the local shop manager too. on the dill which knowing the taste i'm sure is traditional ingredient. i can't see the tarragon just being put in selective dishes. it would have to go in the base or paste. as you point out Asian stores are packed with fresh and dried herb and perhaps we don't use them enough - well not in curry (i have a 250g Natco marjoram for pizza as example).
the use of ajowan as "essential ingredient" for base shows for me that all is not necessarily crucial. i've used ajowan in ifindforu's base some time ago and ended up swapping it for fennel.
i'm still steadily plodding through the book.
of particular interest "bhaji base" which i'd never come across - i think i can use the idea on my oil work.
the rogan josh idea of using de seeded toms lightly fried until breaking up is another to go on to do list. i've never been able to get rogan like i like and this i can see working a treat.
the idea of saving the meat cooking sauce to add to curries is another. i've tried adding it to base and makes no difference. adding to the dish at frying i can see working. think i will ice cube next meat cooking sauce to try out.
i know that chef's do add additional spice to specific dishes but i'm not at that standard. the proportions are banked for future (particularly coriander, i can't see need for turmeric/cumin or curry powder).
having a real good time reading the book.
