Because this site is all about the dishes served up in British Indian Restaurants (and by extension, takeaways), anything that CAN be pre-prepared usually is.
That doesn't mean to say that you MUST pre-cook your chicken, but if you're using a BIR recipe, like CA's for example, you're looking at producing a meal in something under 10 minutes, so you wouldn't want to cook raw chicken using the type of recipe you're looking at.
In saying that, there's nothing to stop you frying the chicken off first and setting it aside before embarking on the recipe proper, then you would simply re-introduce the cooked chicken at the appropriate point in the recipe.
I often do this for a change - even if I have pre-cooked chicken or chicken tikka readily available.
If you want to pre-cook chicken in large batches (say, 1-2kg) which you can freeze for later use, there are loads of recipes which are mainly variations on a theme. Just do a search for them on the site.
As an example, I use
Abdul Mohed's pre-cooked chicken recipe and
mickdabass's chicken tikka recipe as my standards, but there are loads more popular recipes to choose from on the site.
You won't be disappointed with any of CA's recipes - they're very good - and there's loads more great recipes here too. Happy currying!
