It might look like Tomato and mascarpone sauce, but it tastes better. This is what I got from https://www.youtube.com/watch?v=YpqMBueLBtI
Pretty much per the demo, albeit with a red capsicum. It looks like and has the consistency of Tomato and Mascarpone, but does not have the artificial taste that the shop bought sauce has and it has interesting spices, although more subtle than I expected. I'm looking forward to many BIR curries to come. ;-)
The trays are ASDA silocone and each cube is about 30, maybe 35ml from memory. groceries.asda.com/product/serverware-condiments/george-home-silicone-ice-cube-tray - I really like them!
