You get oil back from the base when you cook it. The more oil in the base recipe, the more you get back. Of course if you cook the base out and skim the resulting oil floating on the surface, this will affect how much oil is actually in the base. But this is a point to consider. When you cooked the Ashoka base, did you notice any oil rise to the surface? If a base is cooked out long enough (once blended), the oil within it will rise to the surface. If you blend the oil back in or don't cook it out, then this will appear in your final dish.
I do remember you saying you put too much water in the base when making it. As Jerry says, you'd have to cook this out longer when creating the final dish. Consistency of base is something you need to experiment with, as this will have an effect on how you cook with it. The thinner the base the more reduction it requires. The thicker the base, the less time you have to work with it. It's a hard thing to explain but I make mine to a loose tomato soup if that makes any sense.
Best thing to do is take a ladle or two of base an reduce it in the pan and see how it is affected the longer you cook it and reduce it.
I always pre cook my chicken now before adding it and use an alternative method I came up with that gives great results, only my opinion of course. The advantage is that any excess moisture is drawn out but leaves the chicken succulent and tasty. If you want to take a look at it, i've listed the method here:
