BUTTER AND BUTTER-MAKING As with See also:cheese, so with butter, large quantities of the latter have been inferior not because the cream was poor in quality, but because the wrong kinds of bacteria had taken See also:possession of the See also:atmosphere in hundreds of dairies. The greatest if not the latest novelty in dairying in the last See also:decade of the 19th See also:century was the See also:isolation of lactic See also:acid bacilli, their cultivation in a suitable See also:medium, and their employment in cream preparatory to churning. Used thus in butter-making, an excellent product results, provided cleanliness be scrupulously maintained. The culture repeats itself in the buttermilk, which in turn may be used again with marked success. Much See also:fine butter, indeed, was made See also:long before the bearing of bacteriological.See also:science upon the practice of dairying was recognized—made by using acid butter-See also:milk from a previous churning. In See also:Denmark, which is, for its See also:size, the greatest butter-producing See also:country in the See also:world, most of the butter is made with the aid of " starters," or artificial cultures which are employed in ripening the cream. Though the butter made by such cultures shows little if any superiority over a See also:good See also:sample made from cream ripened in the See also:ordinary way—that is, by keeping the cream at a fairly high temperature until it is ready for churning, when it must be cooled—it is claimed that the use of these cultures enables the butter-makers of Denmark, to secure a muchgreater uniformity in the quality of their produce than would be possible if they depended upon the ripening of the cream through the See also:influence of bacteria taken up in the usual way from the See also:air. Butter-making is an altogether simpler See also:process than cheese-making, but success demands strict See also:attention to See also:sound principles, the observance of thorough cleanliness in every See also:stage of the See also:work, and the intelligent use of the thermometer. The following rules for butter-making, issued by the Royal Agricultural' Society sufficiently indicate the nature of the operation: Prepare See also:churn, butter-worker, wooden-hands and See also:sieve as follows:—(a)Rinse with See also:cold See also:water. (2) See also:Scald with boiling water. (3) Rub thoroughly with See also:salt. (4) Rinse with cold water.

Always use a correct thermometer. The cream, when in the churn, to be at a temperature of 56° to 58° F. in summer and 6o° to 62 ° F. in See also:

winter. The churn should never be more than See also:half full. Churn at number of revolutions suggested by maker of churn. If none are given, churn at 40 to 45 revolutions per See also:minute. Always churn slowly at first. Ventilate the churn freely and frequently during churning, until no air rushes out when the vent is opened. Stop churning immediately the butter comes. This can be ascertained by the sound; if in doubt, look. The butter should now be like grains of See also:mustard See also:seed. Pour in a small quantity of cold water (I See also:pint of water to 2 quarts of cream) to harden the grains, and give a few more turns to the churn gently. Draw off the buttermilk, giving plenty of See also:time for draining.

Use a straining-See also:

cloth placed over the See also:hair-sieve, so as to prevent any loss, and See also:wash the butter in the churn with plenty, of cold water: then draw off the water, and repeat the process until the water comes off quite clear. Ta brine butter, make a strong brine, 2. to 3 lb of salt to I See also:gallon of water. See also:Place straining-cloth over mouth of churn, pour in brine, put lid on churn, turn sharply half a dozen times, and leave for to to 15 minutes. Then lift the butter out of the churn into sieve, turn butter out on worker, leave it a few minutes to drain, and work gently till all superfluous moisture is pressed out. To drysalt butter, place butter on worker, let it drain Io to 15 minutes, then work gently till all the butter comes together., Place it on the scales and weigh ; then See also:weight salt, for slight salting, ,f oz.; medium, a oz.; heavy salting, 1 oz. to the lb of butter. See also:Roll butter out. on worker and carefully sprinkle salt over the See also:surface, a little at a time; roll up and repeat till all the salt is used. Never See also:touch the butter with your hands. Well-made butter is See also:firm and not greasy. It possesses ' a characteristic texture or " See also:grain, in virtue of which it cuts clean with a See also:knife and breaks with a granular fracture, like that of See also:cast-See also:iron. Theoretically, butter should consist of little else than See also:fat, but in practice this degree of perfection is never attained. Usually the fat ranges from 83 to 88 %, whilst water is See also:present to the extent of from 10 to 15 %.l There will also be from 0.2 to o.8 % of milk-See also:sugar, and from o•5 to 0.8 % of casein. It is the casein which is the objectionable ingredient, and the presence of which is usually the cause of rancidity.

In badly-washed or badly-worked butter, from which the buttermilk has not been properly removed, the proportion of casein or curd See also:

left in the product may be considerable, and such butter has only inferior keeping qualities. At the same time, the See also:mistake may be made of overworking or of overwashing the butter, thereby depriving it of the delicacy of flavour which is one of its See also:chief attractions as an See also:article of See also:consumption if eaten fresh. The See also:object of washing with brine is,that, the small quantity of salt thus introduced shall See also:act as a preservative and develop the flavour. Streaky butter may be due either to curd left in by imperfect washing, or to an uneven See also:distribution of the salt.
