My body reacts badly to monosodium glutamate. Parmesano Reggiano is chock full of MSG, as much as 1% by weight (naturally occurring). I love using freshly shaved or freshly grated hard cheeses in cooking, but the MSG can't be tolerated so I'll be switching to Pecorino Reggiano ... except, I've been unabale to discover whether Pecorino exhibits MSG naturally.
Anyone know?
Yes, unless very young.
