I love my MSG
I sometimes see MSG in my local Asian grocery store. I'd heard people say it made you turn green and grow a third eye or something, but I recently threw caution to wind and bought a little.
PRAISE BE TO HEAVEN, THIS STUFF IS AMBROSIA. It makes anything savory taste twelve times better! It does wonders for soups and stir - fries, I've even started putting a little bit in the oil when I make homemade popcorn. It gives vegetarian dishes a little meaty zing.
It's really nuked my cravings for fast food. Before, I'd have an urge to take out Domino's or Pizza Hut pizza every week or so, and this was probably not good for my body or my wallet. But, putting a wee bit of MSG in lentil soup or popcorn makes it scratch that same itch.
Unless you happen to be sensitive to it, I really can't recommend this stuff highly enough. It feels like I was trying to cook without salt or onions before.
