Hi BJ, and welcome to cr0 fella (sorry it's a bit late)
Ok, frying spices v boiling them; for me, spices need to be fried. You need to cook out the rawness, especially chilli powder, although I don't use it in my base.
You will have noticed, I assume, that there are two popular ways of making a base gravy here on cr0, one being the "all in and boil" method, the second being a "two stage" base.
The "all in" base is usually achieved by adding all the veg, tomatoes, and spices in a good quantity of oil, and covered with water. Bring all this to the boil, and simmer for about 40 - 60 minutes or until you can cut the toughest veg with a spoon. Let cool for a while, then blitz.
I don't know the exact science but I guess, with there being a fair amount of oil in there, that it does slightly fry the spices but I couldn't say for sure.
My method, is to, chop all the veg that you are using, add a quantity of oil to the pan, cover with water and bring to the boil. Whilst that pan is boiling away, in a separate pan, I add oil, and gently fry the spices off. I then add a tin of chopped tomatoes, bring back to the boil, then simmer until the tomato mixture thickens into a paste. Once this is achieved, I add the tomato paste to the big pan of veg, and continue to boil until the veg is soft, then blitz.
Either method works fine, as long as you fry off the spices when cooking your main dish.
I guess it's just horses for courses really.
Here's my base for you to get a better understanding of my method
