I made quite a few changes in this.
I did away with the whole fresh coconut thing and used a 245ml tin of coconut milk
I put the ginger, tomatoes, mustard, and I didnt have tamarind paste so I used lemon juice.
i took this out of the tm
Then I did step 4 and at this point I added a teaspoon of fennel seeds and 3 cardamom pods.
Then I did step 5 where I also added half a cinnamon stick and half a teaspoon of sugar.
Then I stuck everything in the tm and cooked MC off for about half an hour reverse temp 100 speed spoon. Then cooked for another hour with MC on speed spoon temp 100.
It is tasting pretty good and its still cooking. It makes quite a bit of sauce so you can leave the mc off for a while if you want less sauce
Edited to add the pic which isnt very mastercheffy as I just splooshed it in there LOL
