Garam masala is meant to taste sweet. However the powder I use doesnt taste sweet it tastes bland. I imagine this is because the powder has oxidised over time. Is oxidation really that bad that it can turn something like garam masala from sweet into bland and so is the only way to get around this to use fresh ingredients?
Additionaly is it the case that even fresh garam masala isnt really tasty but bland, and so you in order to get any real taste chilli or other sweeteners such as paprika, black pepper etc need to be used?
