Went shopping and finally got some things I had been dying to find, namely:
1. Mr Naga paste!
2. Kashmiri Chillies (though I'm judging by the looks as the indian chap at the green grocers couldn't tell whether they were or not)
3. Rajah All Purpose Seasoning for CBM's base (though I realize how unimportant it really is in the context of that recipe.)
4. and just above the green chilli are the seeds that markh3565 kindly posted to me for free! Thanks markh3565!
5. Shan's Special Garlic Pickle that Julian mentions in his recent video and I felt curious about

I managed to tick a lot of the "to buys" this time around! Happy days!
