What is the secret to making jam? ›

Use fresh, dry, slightly under-ripe fruit. Strawberries and raspberries are best layered with the sugar and left for a couple of hours before cooking. Plums, currants, gooseberries, cherries etc need to be lightly poached before sugar is added. Pectin, naturally found in fruit is vital to make your jam set.

(2)Most jam recipes call for a 1:1 ratio of fruit to sugar. I usually use a 75 % ratio, or 1 ½ pounds of sugar to every 2 pounds of fruit, unless the fruit is not very sweet, in which case, I adjust accordingly.

To set, jam needs pectin from the fruit and some varieties have more than others. For extra pectin, add a muslin pouch of lemon rind and seeds. Cook the fruit in a heavy-based pan until it's very soft but still holds its shape. This releases pectin and means your jam won't have tough bits of fruit.

The best jams strike a balance among three ingredients: fruit, sugar and acid. Peak-season fruit is thickened with granulated sugar, which, along with an acid like lemon or lime juice, helps enhance its flavor.

Coarse-grain white granulated sugar is best for jam-making as it ensures a good clear jam, but fine caster sugar can also be used. The coarse grains dissolve more slowly and evenly, giving a better result. Granulated sugar with added pectin is also available, but it shouldn't be necessary to use this.

Lemon juice contains natural pectin, a substance found in the cell walls of fruits that helps to thicken and set the jam or jelly. Pectin is crucial for achieving the desired consistency and texture in jams and jellies.

5. Do Not Stir Once Mixture Is Boiling. Once your jam/marmalade it has reached a rapid rolling boil do not stir it. Stirring it will alter the temperature of the jam/marmalade meaning it will take longer to reach the setting point.

It's important to add the jam sugar at the right time. If you add it in too early, the sugar can cause the fruit to break down and become mushy. If added too late, the jam may not set properly.

Lack of acidity: Acids like lemon juice help lower the jam mixture's pH, which reacts with the natural or added pectin to help thicken the jam. If a jam recipe doesn't call for lemon juice or lime juice, it could rely on another ingredient, like added pectin, to set the jam.

How long should I boil jam for? ›

Boil hard for 5-10 mins until the jam has reached 105C on a preserving or digital thermometer, then turn off the heat. If you don't have a thermometer, spoon a little jam onto one of the cold saucers. Leave for 30 secs, then push with your finger; if the jam wrinkles and doesn't flood to fill the gap, it is ready.

Lemons vary in ripeness and therefore the amount of acid might not be adequate for the jam to achieve the proper set. The best way to ensure you are adding enough acid is to go with a commercial bottled lemon juice because these are controlled and standardized, so the acid content is assured and more reliable.

Whole spices such as cardamom pods, allspice berries, black peppercorns, whole cloves, or cinnamon sticks can be infused in a sachet while the jam cooks, or small amounts of ground spices can be added directly in. Warm spices pair especially well with fruit, and a little goes a long way, so taste as you go!

If you really want to thicken it to a more spreadable consistency, the easiest way is to heat it up with some thickeners such as cornstarch. Arrowroot flour is more delicate and taste-neutral, but most cooks won't have it. Unflavored gelatin may also be used. Bring the syrupy “jam” to boil in a pot.

Tip One: With a decade of jam making under my ample belt, I've found the secret to thickening up runny low-pectin fruit jams: add an apple or two. Pectin is a naturally occurring thickener found in most fruits, though levels vary greatly. For example, apples are high pectin fruits, cherries low.

Commercial pectin helps thicken jam made with low-pectin fruits, like blackberry jam, or vegetable jelly recipes, like pepper jelly. It comes in powder or liquid form, but the former is the most common. Add powdered pectin to the fruit juice, chopped fruit, or strained purée before heating the jam mixture.

The butter prevents the jam from foaming while you're cooking it - the foam is unattractive and spoils the appearance of the jam. Adding a little butter eliminates this problem."

Flavor: The flavor should be well-balanced and not too sweet or too tart. The fruit flavor should be the dominant taste, with just enough sugar and pectin to create the right consistency and preserve the fruit. Color: The color should be bright and vibrant, reflecting the natural color of the fruit.
