Show ammonia in ili raking powder scientific american 1 among the recent discoveries in science ami and chemistry none is more important than tile uses to which cou courmon juon ani ammonia nionia can be properly pr 0 r 1 y put as a leavening agent and which i 1 1 ind indicate irate eliat this familiar salt is hereafter to perform an active part in the preparation of our daily food the tile carbonate of ammonia is an e exceedingly volatile substance place a small portion of it upon a knife and hold it oyer over a flame and it will almost be entirely do v ea aped into gas and pasa pass off into the air the gas thus formed is a simple composition of nitrogen and hydro gen o 0 no residue is left from the ammonia monia this gives it its superiority as a lea venitia power over ove reoda sods a and ad y cream of tartar used alone and lias has induced its wo use as a supplement to these articles A small quantity of ammonia in the dough is effective in producing bread that will be lighter sweeter and more wholesome than that raised by any other I 1 leavening ca agent when it is acted upon by the heat beat of baking the leavening gas that raises the dough is liberated in this act it uses itself up tip as it were the ammonia is entire entirely lv diffused leaving no trace of residuum whatever the light fluffy flaky appearance so de dei in biscuits ae and so sought after by professional cooks is said to be imparted to them only by the use orthis agent the bakers and baking powder manufacturers producing the finest goods have been quick to avail themselves of this useful discovery and the handsomest handsom eat and best bread and cake are now largely risen by the aid of ammonia combined air of course with other leavening mal material te ria I 1 ammonia is one of the me best beat known products of the laboratory if as seems to be justly claimed for it the application of its properties to the purposes of cooking results in giving us lighter and more wholesome bread biscuit and cake it will prove a boon to dyspeptic humanity and will speedily edil force itself into general use in the tile new held field to which science has assigned it |
