I have made the base and froze it (ran out of time)
I found it lacked sweetness, too
This could be down to the onions
Perhaps I didn't cook them long enough (20 minutes)
Or the onions had a particular bitterness about them
One chef, I spoke to, said he sometimes needed to add sugar to the base, so why shouldn't we?
The other option could be, too much spice
Spices are bitter and there are a lot in it
Stew's base seems good, though
I will post when I have used it
I compared it with two other bases I had to hand
If you look at the picture
1 is an experiment base (no good, no subtlety)
2 is Stew's base
3 is a bought base from my favourite takeaway (note different colour)
Bases do come in all colours, it has no reflection on their taste
However,I must say, that the bought base is so much better than anything I can make.
Once again, it is this extra flavour
So frustrating
To be specific, the flavour and smell seems like "poppadoms" (which I love)
I have experimented with using oil that poppadoms were cooked in
I have also added ground cooked poppadoms to the base
No luck!
Maybe it really is just the intense heat of their cookers
