Product Information

Jam: Crushed or chopped fruit that is cooked with sugar, and sometimes added pectin, to a high enough temperature to yield a spreadable consistency. Jam contains pieces of fruit that are still solid, the mixture is not strained. Jam is a condiment. It is usually made from pressed fruit, sugar, and sometimes pectin. Most jams are cooked. After making, jam is normally put into an airtight jar. However, this jam is the perfect way to really enjoy the taste of nectarines over the rest of the year; you never need to go without again. I say jam, although technically I’m making a conserve, as the fruit is macerated in sugar first rather than having the sugar added after the fruit has been cooked down. A: You could be taking its temperature incorrectly (see above), or not adjusting for your location’s boiling point. Altitude is an important factor in the cooking temperatures for jams and jellies. Target temperatures will need to be adjusted depending on your location. High Altitude and How it Affects Temperature When Making Jam Jam recipes mostly comprise equal weights of fruit and sugar. You can play with this 1:1 ratio as much as you want, but too much fruit and you may lose the preserving effects of the sugar; too much sugar and it may crystallise during storage.

Pectin was first isolated by French chemist Henri Braconnot in 1825 and was named from the Greek pektikos, which means congealed or curdled. It is a polysaccharide so, like cellulose and starch, it is made up of long chains of sugar molecules. In fruit, pectin is concentrated in the skins and cores where it acts as structural "cement" in the plant cell walls. In jam, pectin forms a mesh that traps the sugary liquid and cradles suspended pieces of fruit. As a gel, jam is neither a solid or a liquid. It can contain chunks of fruit which are solids. Once opened and out of the fridge the gel becomes more like a liquid, and is able to decay. This is the exciting bit: the smell of jam fills the air and you're desperate to get it into jars and on to some toast, but patience is required. However, you will normally have to wait around 5–20 minutes for the pectin network to form. The time varies depending on the type of fruit, the type of pan etc. A wide-mouthed pan is ideal as it allows water to escape, helping to bring our precious pectin molecules closer together. Time to pour Acids are also important in helping the pectin to set. The COOH groups in the pectin are usually ionised, and the negative charges on the molecules this ionisation causes can cause repulsion, and prevent the pectin chains from being able to form the gel network. To avoid this, we need the pH of the mixture to be roughly in the range of 2.8-3.3. At these more acidic pHs, the COOH groups aren’t ionised, lowering the magnitude of the repulsive forces. Add lids and tighten until finger tight and process for 10 minutes or according to your altitude. Processing Times For Water Bath Canning

Capture fresh fruit flavor with these jam and jelly recipes. You'll find recipes for all kinds of produce from strawberries and rhubarb to tomatoes and lemons.

Sugar not only sweetens the jam and helps the fruit maintain its brilliant color, but it also helps pectin do its stuff. Sugar attracts water, yanking it away from the pectin, which boosts network formation and enhances gelling. Sugar’s water-grabbing activity also helps prevent the growth of molds and bacteria (no available water, no microbes), which gives jam its long-term keeping qualities. If you used more fruit or juice then your recipe called for it changes the amount of pectin you need. Even if you only slightly increased the amount you will need to add more pectin. Was The Pectin Measured Properly?

Water boils at a lower temperature than 212°F at higher altitudes. The temperature at which preserves set, 220°F, will adjust downward as well.” Oh, this is interesting! The excellent Ms. Parks bases that claim on a reading from the book Mrs. Wheelbarrow’s Practical Pantry by Cathy Barrow, but a closer reading of some relevant passages in that book shows more nuance: Fruits naturally contain acids – the most well known is citric acid, but malic acid and tartaric acid are also found in a number of fruits. Whilst some acid will be contributed by the fruit from which the jam is made, often this won’t be enough to reach the desired pH, and for this reason more must be added. This is commonly in the form of lemon juice, which contains citric acid, though powdered forms of acids can also be used. As a rough guide, the juice of a whole lemon (30-40ml) will be needed for very low acid fruit, whereas half a lemon will be enough for medium acid fruit, and you won't need any for the high acid fruits. In general, fruit with high pectin will also have high acidity and vice versa. Adding the sugar For each quart (4 cups) of jelly, you will need 3/4 cup of sugar, 2 tablespoons of liquid pectin, and 2 tablespoons of lemon juice.I love the summer, particularly when delicious and juicy peaches and nectarines are available; they among my favourite fruits. I far prefer sun ripened, seasonal European fruit to that flown in from the Southern hemisphere over the winter, as I find the latter flavourless and with unimpressive food miles. Gelling also requires a little acid in the mix. Pectin molecules, liberated from fruit cells in the form of free-floating polysaccharide strands, repel each other: Pectins carry a negative electrical charge, and like charges simply don’t get along. For low-acid fruits, therefore, jam and jelly recipes generally call for a shot of lemon juice—enough to neutralize pectin’s negative charges and promote network assembly. Optimum pH for persuading jam and jelly to gel is somewhere between 2.8 and 3.3. First cut up the fruit and remove the stones. This does take a moment, but the big advantage of making small batches of jam is that I don’t spend all afternoon cutting nectarines – we’re only using about 4 large nectarines in this recipe. Any jam or jelly must be heated to a rolling boil for enough water evaporation to occur, and reach the appropriate sugar concentration. This stage of the jam’s ratio of sugar to water is measured through temperature. The target temperature range of jams and jellies is 217-222°F (103-106°C)—the target temperature may vary slightly for each recipe. Sugar Concentration:

Do not reduce the amount of sugar. The final sugar concentration is critical for proper gelling. If a low sugar option is needed, use a reduced sugar recipe that has been developed to compensate for the lower sugar concentration. If you were to use regular pectin you would have to add the full amount of sugar you used in your recipe over again making the finished product way to sweet. Ingredients & Supplies Don’t use more than 6 cups of crushed fruit in your recipe. Amounts larger than this just can’t reach the right temperature that is needed for the recipe to set properly. A: The answer is in understanding the critical variables needed to properly set pectin: Sugar, acid, and temperature. Keep reading… The Science of Pectin

Then add the jelly or jam that you want to recook and bring it to a rolling boil over high heat, stirring constantly.
