Hi Jerry
If it is of any interest at all to you, these days this is pretty much the only tikka recipe I use. Despite what may have been measured in the group tikka test

I still stick by the accidental descovery of substitution of a different paste -
https://curry-recipes.co.uk/curry/index.php?topic=874.msg52375#msg52375No one else has reported back that they have tried the substitution? would you perhaps care to try?
Also, always used to use the 2 tbsp pre-marinade, but stopped of late feeling I could not tell the difference in final outcome. So just 2tbsp total now for me, seems to work well. If you have it cold the next day, you can taste a lemony zest comeing through, but don't let that put you off, its bloody delicious

Regards
