All paste should be made in a very cool place, as heat renders it heavy. It is far more difficult to get it light in summer than in winter. A marble slab is much better to roll it on than a paste-board. It will be improved in lightness by washing the butter in very cold water, and squeezing and pressing out all the salt, as salt is injurious to paste. In New York and in the Eastern states, it is customary, in the dairies, to put more salt in what is called fresh butter, than in New Jersey, Pennsylvania, and Delaware. This butter, therefore, should always undergo the process of washing and squeezing before it is used for pastry or cakes. None but the very best butter should be taken for those purposes; as any unpleasant taste is always increased by baking. Potted butter never makes good paste. As pastry is by no means an article of absolute necessity, it is better not to have it at all, than to make it badly, and of inferior ingredients; few things being more unwholesome than hard, heavy dough. The flour for paste should always be superfine. You may bake paste in deep dishes or in soup plates. For shells that are to be baked empty, and afterwards filled with stewed fruit or sweetmeats, deep plates of block tin with broad edges are best. If you use patty-pans, the more flat they are the better. Paste always rises higher and is more perfectly light and flaky, when unconfined at the sides while baking. That it may be easily taken out, the dishes or tins should be well buttered.
