1791. Domestic Hints (Apple Sauce with Pork and Goose). Why is apple sauce eaten with pork and goose? Because it is slightly laxative, and therefore tends to counteract the effects of rich and stimulating meats. The acid of the apples also neutralizes the oily nature of the fat, and prevents biliousness. 1792. Domestic Hints (Thunderstorms Souring Milk). Why does milk turn sour during thunderstorms? Because, in an electric condition of the atmosphere, ozone is generated. Ozone is oxygen in a state of great intensity; and oxygen is a general acidifier of many organic substances. Milk may be prevented from becoming sour by boiling it, or bringing it nearly to boiling point, for, as the old proverb says, "Milk boiled is milk spoiled." Heating the milk expels the oxygen. 1793. Domestic Hints (Butter from Churning). Why does the churning of cream or milk produce butter? Because the action of stirring, together with a moderate degree of warmth, causes the cells in which the butter is confined to burst; the disengaged fat collects in flakes, and ultimately coheres in large masses. 1794. Domestic Hints (Blue Mould on Cheese). What is the blue mould which appears sometimes upon cheese? It is a species of fungus, or minute vegetable, which may be distinctly seen when examined by a magnifying glass. 1795. Domestic Hints (Tenderness in Birds). Why are some of the limbs of birds more tender than others? The tenderness or toughness of flesh is determined by the amount of exercise the muscles have undergone. Hence the wing of a bird that chiefly walks, and the leg of a bird that chiefly flies, are the most tender.
