Parisian barm makes a nice showy loaf, but for flavour I prefer German yeast. To make Parisian barm 1 gallon of water is put into a pan at, say, 140° Fahr.; weigh 2 lbs. of crushed malt, put it into the water at the above temperature, cover it up for about three hours; one hour before you are going to make your barm, that is two hours since you put your malt to steep, put 3 gallons of water into a large pan, put it on the fire; when it boils, add 2 oz. of good fresh hops, well boil for twenty minutes; after which well strain the malt through a hair sieve. Put it into the barm tub and add as much flour as can be nicely stirred in with the barm-stick. Then put the boiling hop-water through a sieve on top of the malt water and flour and well stir it. It should be properly scalded. Some put the hops in a small linen bag made for the purpose and put it in the boiling water, squeezing it against the side of the pot before taking it out. Supposing it to be five o’clock in the afternoon, it may be put by with a couple of sacks over it till five o’clock next morning. Then “set the barm away” (as they say in Scotland), by adding to the above liquid half a gallon of the barm previously made. After the old barm is added to the new, in a few hours a scum gathers on the top. This scum will either start at the side of the tub and work gradually to the other side, or I have seen it start in the middle and work itself slowly to the sides of the tub. When ready it should have a nice clear bell top. It takes from ten to twelve hours to work before it is ready. By following this method one may always have good barm. Cleanliness is very essential for barm, and care should be taken that neither grease nor churned milk shall get near it. We need scarcely say that experience is required in this as in other things. AMERICAN PATENT YEAST. I may add the following recipe for American patent yeast:--Take half a pound of hops and two pailfuls of water; mix and boil them till the liquid is reduced one half; strain the decoction into a tub, and when luke-warm add half a peck of malt. In the meantime, put the strained-off hops again into two pailfuls of water, and boil as before till they are reduced one half; strain the liquid while hot into a tub. (The heat will not injuriously affect malt previously mixed with tepid water.) When the liquid has cooled down to about blood heat, strain off the malt and add to the liquor two quarts of patent yeast set apart from the previous making by the above process. Five gallons of good yeast may thus be made which will be ready for use the day after it is made. It takes about eight hours’ time to manufacture, but gives very little trouble to the baker. GOOD OR BAD FLOUR.
