The improved modern method, now in practice by the best butter makers generally, is to stop the churn as soon as the butter is collected in particles the size of wheat kernels. Just before this, when the first signs of the separation of the butter is seen, the sides of the churn are washed down with cold water--usually below 60 degrees, or about 55 degrees--to not only prevent waste, but to harden the butter and make it easier to handle. When the granules are the size of wheat kernels, the butter is drawn off or the butter taken out of the buttermilk, as the case may be. If the butter is left in the churn, water is poured in to float the butter, which is then gently agitated a moment and the water drawn off. This operation is repeated until the water runs clear. Sometimes one of the washings is in brine, which coagulates the caseine into a soluble form and prepares it to be washed out afterward. In this way, it is believed that purer, longer-keeping butter can be made. In some cases, however, butter makers have customers who want a buttermilk flavor in their butter. They, therefore, do not wash the butter, or wash it very little. Such butter must be consumed at once, as it will not keep. WORKING. By this method of retaining the butter in a granulated form, only sufficient working is required to evenly work in the salt. The less working the better. SALTING. The salt, after the butter is properly drained, can be carefully mixed with the butter by stirring. When thoroughly incorporated, barely pressing the butter together into a solid mass is all that is needed. If one does not want butter very salty to the taste, it can be evenly and nicely salted by completely wetting it with saturated brine, then carefully pressing the granulated butter together and leaving in it as much of the strong brine as will remain. We have seen butter salted in this way, and it was very evenly and completely salted, having in it no undissolved grains of salt, but it was not as salt to the taste as some like. About an ounce to the pound is good salting; but more or less salt must be used to suit the taste of customers. None but refined salt should be put into butter. No salt is better for this purpose than the Onondaga F.F., which is American, and the cheapest salt fit for dairy use that can be obtained. The principal office of the salt in butter is to impart an agreeable flavor, in conjunction with the natural aroma of fine butter; but it is a fact that too much salt injures good flavor, and it may, to some extent, be used to cover up or neutralize bad flavors. We do not recommend its use for this latter purpose, preferring that the natural flavor of butter from pure cream should be preserved. SALT AS A PRESERVATIVE.
