but supermarket curries list turmeric, coriander, garam masala etc the same as BIR curries, string...which cost pence a packet....and having checked out some of the prices, ?1.49 is a gross underestimation...BIRs also use cheap ingredients, string if you think they use all the most expensive ingredients you're kidding yourself.
If you were to make a supermarket frozen pizza fresh at home using the same ingredients, I'd be willing to bet that a freshly made pizza base would taste different even if made with the same ingredients, the tomato sauce would taste different freshly made and used immediately....would it taste better home-made? I'd bet that it would....cheap ingredients or no... :
