Conserve: Jams

One of the nicest things about the summer months (aside from warmer weather) is the great rush of fruit that floods the markets: strawberries, peaches, cherries, melons, apricots, plums, wild berries, and all sorts of other things.

In the past this bounty did more than liven the table; the arrival of each new fruit occasioned a burst of activity in the kitchen as well, as cooks made it into jam or preserves for everyday use, and to carry a little bit of summer over into the winter months.

Despite the ready availability of commercially prepared jams and preserves, there are still advantages to making them at home. First, you can tailor the recipe to suit your taste -- commercial producers aim to please everyone and consequently leave out ingredients that some might object to, for example cloves. Also, you can (within reason) regulate the sweetness of your product -- those of commercial outfits are often cloyingly sweet, because the process by which they extract the juice from the fruit forces them to add pectins that in turn require addition of sugar to make everything jell. You can experiment -- La Vecchia Fattoria, one of Italy's most popular cooking and gardening shows, showed how to make cantaloupe marmalade. If you have or have access to a fruit tree, jam making is a great way to preserve the harvest. Homemade jams and preserves are great gifts. And finally, making jams and preserves is fun.

How to go about it:

To begin with, fruits can be divided into two categories, those with high pectin contents and those with lower pectin contents. If you make a jam or preserves with the latter it will help the jelling process if you add some of the former or a commercial pectin, though it is not absolutely necessary. I have had good results using commercially prepared pectin extracted from apples.

Not sure if your fruit is high or low pectin? Put a tablespoon of the cooled fruit juice produced by the cooking of the fruit into a glass, and add a tablespoon of grain alcohol. Shake gently; the alcohol will cause the pectin to collect in a transparent blob. If there's lots of pectin it will appear as a single blob when poured from the glass, and you should use equal volumes of sugar and fruit. If the pectin forms 2-3 blobs, the sugar should be 2/3 to 3/4 the volume of the juice, and if it forms still fewer blobs the sugar should be 1/2 the volume of the juice, unless the fruit is quite tart.

In selecting fruit for making jam, be sure that it is ripe, flavorful, and blemish free. This is one occasion when looks really don't count for much; if you're uncertain about the quality of the fruit close your eyes and take a deep sniff. If you're not greeted by the heady aroma of ripe fruit the jam won't taste of much either.

How much to make? Jams and preserves come out best made in small batches -- 1 to 1.5 quarts (liters) at a time. If you have more fruit make a second batch. Lightly crush the fruit with your hands and put it in the pot, adding a little water if it's a relatively dry fruit, for example apricots. Heat over a low flame, stirring often to prevent sticking or burning, until the fruit has become soft, then add the sugar. Continue stirring while the sugar dissolves, and then reduce the heat and continue to cook until the jam thickens to the point that a drop on a tilted plate runs slowly (keep in mind that it will thicken further as it cools, so don’t let it get too thick); this could take up to a half hour. Taste as you go; should the jam be too tart add more sugar, and if it is overly sweet add some lemon juice.

Once the jam is done you should transfer it to sterile jars with metal lids (wash them if need be with boiling water). Pour the hot jam into them, leaving a little bit of air space, and screw the lids on tightly. Let the jars cool on a metal rack. When they have cooled, tap the lids lightly with a spoon or knife; if they ring the seal is true. Should the lid of a jar fail to ring, either reseal it or use it (you could, for example, make a crostata. Store the jam in a cool dry place; it will keep for a year or more.
