Hi , i make incredibly thin low spiced bases, and dont have the problem. try these ideas. 1) fry a large tsp of garlic ginger paste for 3 mins. 2) use 1.5 tsp of decent spice mix (eg the DD spice mix, or BE spice mix) use a nice big tsp of chilly powder, try adding a couple of green chillies for things like jalfrezzi. chopped up red or yello , or green peppers (around 1/5th per dish) helps the flavor. dont be shy of using good rock salt. i use 1 tsp per dish. getting the tomato puree level right is also essential (2 or 3 tsps of watered down puree) . to increase flavor try turning the heat up higher, and fry the spices longer. this has a massive influence on the strength of taste. but you need to experiment with this to find the right strength. too much heat and its all ruined, so tread carefully !
