Thanks Garp. The curries were all delicious and I'm now really pleased with the level of proficiency I'm achieving. They must have been OK because there wasn't a whole lot left over.
One thing that doing a big cook like this does is illustrate the ability of full-time restaurant and T/A staff. To be able to churn this stuff out at high quality would take a lot of skill, particularly so in the smaller operations with low staff numbers. I had the luxury of time which they don't have. Of course a commercial kitchen would help. I think I had to wash up about 10 times over the course of 2 days.
Sverige, to answer your question, the Laziza Chicken Tikka Masala (Spice Mix) comes in a box of 100gms in 2 individual pouches, I think it cost me about AUD$3.00. The instruction on the back says to use:
1.5 kg of chicken pieces scored in criss-cross pattern,
1 Tbsp of Ginger Paste and
8 Tbsp of Lemon juice for
1 packet of spice mix.
I didn't read the box very well and dumped a whole packet on about 1 kg of Thigh fillets. (It didn't matter and they were just a little bit spicy). I also included some garlic and a little yogurt in the marinade to make it a bit more clingy. The instruction tells you to brush with butter / ghee / oil while rotating during the grill process. I didn't as I cooked them in the tandoor. I'm assuming this instruction is for a horizontal grill / bbq. After I'd cooked my first batch of thigh there was still plenty of marinade left so I put the kg of breast fillet in and they were fine so I would say 1/2 a packet is suitable for 1 kg of chicken quite adequately, so it's pretty affordable and easy.
Of course there would be no reason that this spice powder could not be used in conjunction with more elaborate Tikka recipes or in a Tandoori Chicken marinade. I'll be getting some more of it as I only bought 1 box to try.
Modify PS: The Balti Lamb Korma I refer to as my pick is just so reminiscent of Korma I used to enjoy from a particular restaurant 30 years ago. I loved it back then and this recipe is just so close. It was also my wife's favourite out of the batch both times I've cooked it. I've only made it twice now and it will be my turn to Korma recipe every time moving forward. I use the Misty Ricardo eBook pre-cooked lamb and then follow the Birmingham Balti Co "The Balti Secrets" book recipe for Lamb Korma Balti to the letter. page 78.
