Peaches are commonly used in home canning.
Making jams is a great way to have fresh fruit all year round. There are hundreds of recipes for jams, jellies, marmalades and preserves available online and in cookbooks to help determine quantities and cooking times, but what makes a good jam truly great are some expert tips. Some of the best jam making tips include picking the best fruits, making sure the equipment is sterilized, cooking jams in small batches with big equipment, and experimenting with fun flavors. With a good basic recipe and a few of these tips, great homemade jam can take just a few hours.
The jam is made from all parts of the fruit, resulting in a thick, textured paste, but it does not contain large pieces of fruit.
Great canning starts at the market or in the garden when the best fruit is available. While some people can make excellent jams from slightly overripe fruit, expert chefs say that the best color and flavor come from unbruised fruit at the height of the season. Check farmer’s market guides to find out when each fruit is at its peak, as out-of-season fruit often tastes bad. In most regions, the best time to make jam is from late spring to late summer, when berries and stone fruits are at their peak.
Fresh pickling ingredients can usually be found at a farmer’s market.
One of the most important steps when canning is ensuring sanitation through sterilization. Since preserves are stored for long periods of time, they are vulnerable to bacteria buildup, which can be harmful. Jam jars and lids need to be sterilized before use, as well as any equipment that comes into contact with the jam, such as spoons or jars. Sterilize jars and lids by placing them in the dishwasher on high heat, placing them in boiling water for several minutes, or filling jars with boiling water. The edges of the jars should be wiped clean with a sterilized towel after the preserves have been poured and sealed tightly.

While it can be tempting to double or triple jam recipes, it’s easier to maintain perfect consistency if you work in a small batch. Putting a large amount of ingredients in a single pot can alter cooking times; the top fruits, for example, may not be cooked as often as the bottom ones. It is also more difficult to mix sugar, pectin and other additives to a perfectly uniform consistency in a larger batch. In addition to working with small amounts, consider using a large pot. Since boiling preserves tend to bubble, it helps to have a larger pot to prevent the preserves from boiling over. Another important quantity tip when canning is to leave a little room in each jar when filling; the seal may burst if the jars are overfilled.

Beginners may be tempted to stick with basic single-fruit recipes, but the intrepid jam-making chef should never fear experimentation. Mixing fruits and adding spices can lead to incredible results, although odd disasters can occur. Consider blending ripe plums with ground cloves or making a fruit compote with pits from peaches, nectarines and apricots. As long as the individual fruit is ripe and correctly prepared, the jam is likely to be tasty regardless of the mix.
