I really love Bhuna and tikka sauces just not the creamy type. I like curry quite dry iykwim.
I never seem to get the spice ratio right and end up wasting loads as its too hot! and i cant stand yoghurt and things in it so cant cool it down!
I am so awkward!!!

Am going to check some out and try and find one that is not too high!
If it's too hot you're just putting too much chilli/chilli powder in, dont worry about the other spices, they're not so much heat, just flavours.
Why not just omit the yoghurt/fromage frais or whatever creamy thing they put in the recipes - none of them are essential, the recipe wont taste dire or anything just because you dont put them in, its just to make the recipe creamy and if you dont like creamy thats fine (Im not a fan either).
If you dont want to cook your own you can get tikka spice kits in the supermarket for sure, not sure about bhuna. You can order pretty much anything online though. Ebay, SpicesofIndia.
If you do want to cook your own: for a basic curry recipe fry an onion or two, a few chopped garlic cloves and a tsp or two of grated ginger. When it starts to soften add your chosen ground spices and stir fry for a minute or so, then add a tin of tomatoes, a stock cube, maybe a tbsp tomato puree and your meat/Quorn/veggies or whatever.
You can omit almost any of these if you dont like them and add anything you do. You can adapt most recipes from that to whatever suits your taste. Standard spices would be cumin, coriander, turmeric (with or without chilli powder, to taste); then maybe fennel, fenugreek, mustard seeds, hing... Bit of garam masala at the end. Depends on what you're making. Whole spices are best fried until they pop at the beginning.
