"'Get firm, large berries, and stem but do not wash them. Weigh three-quarters of a pound of sugar to each pound of fruit, and arrange them in layers in your kettle; cover and let them stand all night (or if the weather is very hot and damp, do this in the early morning and cook them toward night). The next morning put the kettle on and bring the berries slowly to the boiling point and skim them. Simmer exactly fifteen minutes and take the kettle off the fire; cover it with a thin cloth and let it stand all night without moving. In the morning heat again, and skim; this time let it simmer exactly ten minutes and take off the kettle; drain off the juice and boil down for just five minutes, put the berries in, and put them in the cans and seal.' That's a queer rule," Dolly commented as she finished.
"It's perfectly splendid, and we will follow it to the letter and you shall see for yourself. Now remember this important thing that I am about to tell you, for it is something you must never lose sight of when you do up fruit: the reason why any fruit spoils, when you put it in good, air-tight cans, is that you have not sterilized the cans and covers, and have not used new rubbers each year."
"But just how do you sterilize cans?"
"Wash them, and then put them in the oven, tops and all, and bake them half an hour. Put the rubbers in hot water for fifteen minutes and wipe them dry. And always use glass cans with glass tops fastened on with wires. When you put the fruit away, find a place for it in a cool, rather dark closet. If you do all these things, none of it will ever 'turn' or spoil."
"Well, I'll impress it all on my mind. Now tell me what we are going to do up this summer, and all about it."
"Currants come first. I shall make jelly of some of those, and later on we will spice them and make conserve, and mix some with raspberries for another sort of jam."
"Does your jelly always 'jell?'"
"Always. It has to, whether it wants to or not. Most jellies are perfectly easy to make, so you can follow a good cook-book; currant jelly is the only sort you could ever have any trouble with, and that you need not have if you follow this rule. Write down:
"'Currant Jelly That Never Fails. Take currants that are barely ripe, and do not pick them just after a rain, when the juice is thin. Do not stem them or wash them, but look them over carefully and crush them in a crock with a wooden potato masher. Put them in a bag, and hang them up and let them drain all night. In the morning measure the juice and take just as much sugar, with the addition of one extra half-pint at the end; put this in the oven to heat. Put the juice on the fire and boil it twenty minutes, skimming it occasionally; then put in the hot sugar and stir till this is dissolved. Let it boil up hard just once, and take it from the fire immediately, for the jelly has come; longer boiling will prevent its ever setting. Pour it into glasses and put it in the sunshine for two days, then cover with paraffin and put it away. This is perfectly clear and of a fine flavor.'"
"So it is," Mrs. Thorne added, as Dolly copied the last words. "Next let us make a sort of list of what you can put up when you are where you can get fruits cheaply in summer. When you are in town you cannot well do them by the wholesale, but a glass or a can when you can find something reasonable, such as a box of nice berries one day, and a quart of nicer plums the next, and so on."
