Sorry for the double questions. I'm looking at two recipes of chicken tikka masala and one has both cayenne pepper (1/4tsp) and red pepper flakes (1/2tsp) I can only find red pepper flakes where I live. My understanding is that they're both made of the same kind of pepper. So, for this recipe would it be okay if I just add extra pepper flakes in place of cayenne?
The other chicken tikka masala recipe calls for chili powder (2tsp), which I think for Americans means a mix of several spices. (Where I live chili powder and red pepper flakes are the same thing) They don't have it here either. I found some recipes for chili powder blend but they require cayenne (again!) and onion powder, neither of which I have. So, what's a recipe for chili powder that has neither but still would taste similar to the original?
So, what should I do and which recipe should I use between the two that would yield a better result despite my lack of ingredients? Thank you in advance for your answer.
