Beer and other foamy things

an article about Perkowitz is HERE..

Foamy facts you might not know:

A brief sampling of fun foamy facts gleaned from the chapter on edible foams: (1) No-fat, ice cold milk froths the best. (2) Non-dairy aerosol whipped cream contains polysorbate-60 and xanthan gum, both ingredients found in shaving cream. (3) You get a fluffier meringue if you beat the egg whites in a copper bowl. (4) Beers with smaller "heads" of foam actually taste better than those with more aesthetically pleasing larger heads. (5) Beer and bread are closely related; when beer is brewed, it produces a fermenting agent called "barm" as a froth, which is then skimmed off and used to make raised bread. (6) To retain its effervescence the longest, it is best to drink champagne from tall skinny glasses (and, adds Perkowitz, "as often as possible").

and he has a book about foamy things.LINK
