Okay guys, so after having made SNS's base this week-end today I tried to made a madras, following SNS recipe as well.
It was not a disaster, but there is a lot of room for improvement I think

First of all concerning the base :
I followed the instruction but I noticed something that bothered me during the cooking, at some point after having boiled the vegetables and blended them, I had some "foam" (not really sure about the word) that would rise up from the pan. I was not too sure what was in it. Any ideas what I did wrong there?
Concerning the madras :
I did not use enough prawns, but that is my fault, I'll use more next time, how much for 2 persons would you say?
My curry paste was way too liquide, I must have added too much water at start I think.
So in conclusion, it was eatable but there is a lot of room for improvement,I will try again soon and give reports

EDIT: I forgot to say that I tried to make two portions at once, for my Gf and me, should I do one after the another or is that ok?
