Recall using the tikka botti packet and it was pretty good. The paste is top notch though, imo. I googled the ingredients for the packet and copied them for the paste.
Packet
Red Chilli, Coriander, Powder, Salt, Turmeric, Dried Garlic 3%, Dried Ginger 3%, Dried Mango, Paprika, Roasted Cumin Powder, Black Pepper, Cardamom, Tartaric Acid, Food Colour E-110 (FD&C Yellow 6), Food Colour E-129 (FD&C Red 40).
Paste
Red Chilli, Coriander, Salt, Turmeric, Soybean oil, water, garlic 7 %, Ginger 7 %, Roasted Cumin Powder, Black Pepper, Cardamom, Colour Paprika Extract, Acidity Regulators Citric Acid (E-330), Acetic Acid (E-260).
I was expecting more ingredients. No artificial colours in the paste, which is probably why I add some (BIR style). Definitely root ginger in the paste. You can see it. Reckon the plentiful steeped oil in the paste lifts it to another level.
Worth a go Santa, either. I think the consensus on here was that Laziza is best for a tikka starter, it's rather bold for some of the milder curries.
I find all other tikka offerings pretty dull by comparison, even though they usually need more prep. Don't get me started on some of the rubbish TA/restaurant tikka, hereabouts anyway

Agree with livo on their other packet mixes. In particular had some good results using the Yakhni Pulao. Just adding it to one-pot trad style curries. Had no luck with their seekh kebab mix though.
