I eat alot of asian soup noodle dishes. Its a genre I love. Over the years every so often I get a taste from the noodles in the soup that reminds me of ammonia. I hate ammonia and part of me thought maybe I was imagining thinngs. Well yesterday I was having some Hong Kong style noodle soup and once again I got an ammonia taste. I decided to figure out what it is and a quick search shows me that Im not imagining it and it is alkali in the noodles that causes this.
Ammonia shows up in a variety of foods. Obviously old cheese (especially Stilton) can get pretty strong. And white mushrooms if you keep them too long can begin to smell like ammonia.
The oddest thing – around the world, people use other things for baking powder than we do. I think those Danish butter cookies that come in a tin, know what I mean? I think they are made with ammonium chloride as part of the baking powder, and you can get a definite whiff of ammonia while eating them. I think it blows off if you leave them out of the tin for a while.
