Phew! What a question!
Okay. Please let me break it down, so even
I can figure out what I'm asking!

A. I have an 'Instant Pot' / Electric Pressure Cooker. I like making curries in it. But, I find
Any water I add just ends up as Water. Thus; I use 1/4 mug of water, to mix the curry powder with, for better distribution? Washy, sloppy curry. And this is a curry that lasts me three days! (1/3 to 1/2 a pot?)
B. I'm now looking at " British Indian Restaurant " Basic Curry Gravy recipes. Great! Chuck out the curry powder and water stuff. Just chuck in my usual curry material and lash This stuff in!
Thicker, not swimming in water, curry. Tastier too, because of all that goes into the gravy

I can't wait!
C. Only question really remaining is;
How much gravy might I need add? A curry swimming in 'Hot Water' isn't the best. One drenched in plenty of that lovely, thick, complimentary sauce is quite another thing.
Brimming with other curry and EPC questions. Just looking to connect with a like mind or two, to explore and get some guide lines.
Thanks
