Christmas Jam Canning Recipe (2024)

FAQs

Do you need to add lemon juice when canning jelly? ›

Acid: The proper level of acid is critical to gel formation. If there is too little acid, the gel will never set; if there is too much acid, the gel will lose liquid (weep). For fruits low in acid, add lemon juice or other acid ingredients as directed.

Do not simply reduce the amount of sugar in a given full sugar recipe. Chances are the jam/jelly will not gel and the end result will be more of a sauce. To prevent spoilage, process jars of low-sugar jams and jellies longer in a boiling water-bath canner than regular jams or jellies.

Put the jam into containers and freeze: Pour the jam into clean freezer containers or canning jars, leaving 1/2-inch headspace. (Plastic freezer containers with tight-fitting lids work well for storing freezer jams and jellies.) Cover the containers and let stand for 24 hours, or until the jam has set and become firm.

I generally add one ounce of lemon juice for every two pounds of fruit when jamming higher-acid fruit (like tart plums, cherries, or raspberries), and about two ounces for lower-acid fruit (like sweet strawberries).

1. Lime juice. Lime juice is the best substitute for lemon juice, as it can be used as a one-to-one replacement and has a very similar taste and acidity level ( 5 ). In fact, when canning or preserving food, it's the ideal substitute for lemon juice because it has a similar pH level.

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.

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.

to legally be called jam the product must contain a minimum of 60% sugars (that includes natural fruit sugar and added sugar).

Lift the spoon of jam above the pan about 12 inches and tilt the spoon horizontally. Watch how the jam runs back into the pan. You are aiming for a cascading sheet-like fall, not a single line of runny jam.

If you simply take fruit and cook it with some sugar to sweeten it a little, it will get thick enough to turn into jam by the naturally occurring pectin in the fruit and the process of reduction. Reduction occurs when we simmer the fruit, and the liquid turns to steam and evaporates, which thickens the jam.

How long do you boil jam for canning? ›

Bring to a rolling boil, cover the canner and boil for 10 minutes if using 4-, 8- or 12-ounce jars or for 15 minutes if using 16-ounce jars. (Check individual preserve recipes for more specific processing times.) Let cool for 10 minutes before removing the jars from the pot.

Sugar serves as a preserving agent, contributes flavor and aids in gelling. Cane and beet sugar are the usual sources of sugar for jelly or jam. Corn syrup and honey may be used to replace part of the sugar in recipes, but too much will mask the fruit flavor and alter the gel structure.

A: For best quality, it is recommended that all home-canned foods be used within a year. Most homemade jams and jellies that use a tested recipe, and have been processed in a canner for the recommended time, should retain best quality and flavor for up to that one year recommended time.

The salt form of Benzoic acid i.e. Sodium benzoate is one of the most common chemical food preservatives. Sodium benzoate is a common preservative used in acidified food such as fruit juices, jams, pickles, preserves, fruit co*cktails, etc.

Lemon is crucial to balancing those sweet flavors, but it also helps the pectin to firm up the jam.

A second reason for using bottled lemon juice in jam recipes is to prevent the growth of bacteria and insure safe canning. With a lower pH, jams can be processed in a boiling water bath for a small amount of time dependent on altitude.

Citric acid gives an acidic taste to passion fruit jelly with dutch eggplant. Citric acid changes the properties of melting easily or increases gel formation. The effect of citric acid makes elasticity of passion fruit jelly with dutch eggplant quite popular.

Citric Acid can be substituted – it will adjust the acidity (lower the pH) of the fruit, which is what you want to do. ¼ teaspoon powdered Citric Acid is equivalent to 1 Tablespoon lemon juice. 1 teaspoon powdered Citric Acid is equivalent to ¼ cup lemon juice (4 Tablespoons).
