I saw it again today. In a sea of Chinese ingredients at a Chinese restaurant I spied a bottle of Maggi Seasoning Sauce. I've been in plenty of restaurant kitchens, from my days as a cook & working for Sysco. I've seen it in all types of Asian restaurants, Mexican & South American restaurants, German & especially Swiss places. I have a small bottle that I'll use to darken a sauce much like "blackjack" does. Their website states that it brings umami to the dish. What do restaurants use it for?
