Perhaps the prettiest sight in the kitchen is homemade jelly. There is nothing like a row of translucent, stained-glass jars full of colorful jelly. Learn how to make jelly at home with this beginner’s guide, including tips on water-bath canning for storage. Plus, see our basic jelly recipes—classic grape, apple, blackberry, cranberry, mint, and dandelion!
What Is Jelly?
Jelly consists of three basic ingredients: fruit juice, sugar, and pectin. When cooked together and allowed to cool, they thicken to form the sweet, spreadable substance we know as jelly.
To make jelly from scratch, we start by using the whole fruit, including the peel and core, which is cooked down and strained for the resulting juice and pectin. Pectin is the natural fiber (starch) within a fruit that helps the liquid juice solidify.
Jam vs. Jelly
Although the process of making both jams and jellies involves using whole fruit, the finished jelly product contains just the juice of a fruit, whereas finished jams and preserves contain bits and pieces of the fruit itself. This is why jelly is so smooth compared to jam.
- Fruit that is fresh and high-quality. You will get out what you put into jelly. Always use the exact amount of fruit noted in the recipe—no more, no less. This helps maintain the correct balance between ingredients. If your schedule doesn’t allow you to make jelly when the fruit is fresh, freeze the extracted fruit juice and make the jelly another day. Freeze juice in straight-sided containers filled to about ½-inch from the rim.
- Sugar increases the volume of the juice, sweetens it, sets the jelly, and helps prevent mold and fermentation. Use the exact amount of sugar listed in the recipe. If you wish to use less sugar, use a recipe specifically developed to get the taste you want. Note substitutes such as corn syrup and honey mask fruit flavor.
- Pectin jells the juice when it is cooked. Some fruit has plenty of natural pectin, while others require added pectin to jell properly. You can buy pectin which available in both powdered and liquid form and be sure to follow the manufacturer’s directions.
- Acid thickens the juice. As with pectin, some fruits will have enough acid and other fruits need to be supplemented. You can use lemon juice for the acid.
Which Fruits Will Need Added Pectin and/or Acid?
- With some fruits, you have enough natural acid and pectin without the need to supplement. Examples are tart apples, crabapples, blackberries, cranberries, gooseberries, and some grapes.
- Other fruits will need added acid, pectin, or both. These include apricots, blueberries, peaches, raspberries, strawberries, and pears.
The recipe will make it clear if you need extra acid and/or pectin.
- Use a large, heavy, 8- to 10-quart stainless-steel sauce pot with a flat, heavy bottom and high sides.
- Have jelly jars, bands, and lids on hand. Lids must be new. Jars and bands can be reused; check that they’re in good condition with no cracks or chips and clean thoroughly after use. Use only the jar size specified in your recipe. For most jellies, half-pint (8 oz) or smaller jars are used.
- A damp jelly bag or cheesecloth is needed when extracting juice for jelly. Firm, unbleached muslin or cotton flannel with the napped side turned in, or four thicknesses of closely woven cheesecloth may be used.
- A jelly, candy, or deep-fat thermometer can be used to determine doneness in jellied products without added pectin. This is not necessary when you supplement with commercial pectin.
- A boiling water bath canner is necessary for processing all fruit spreads to prevent mold growth. A deep cooking pot with a rack that fits the bottom of the pot may be used for a canner if it’s deep enough for one or two inches of boiling water above the tops of jars. Be sure the pot has a close-fitting lid.

Basic Jelly-Making Process and Tips
Our specific recipes can be found farther down the page, but this is the general process for making jelly. It may look like a lot of steps, but it moves quickly and we simply want to provide plenty of detail!
- Get out your recipe. Remember: Only prepare ingredients for one recipe at a time. Do not double. If a larger quantity of juice is used, longer boiling is needed, which can cause a loss of flavor, darkening of the jelly, and toughening of the jelly.
- Wash your jars, lids, and bands beforehand in hot, soapy water and rinse. Sterilize the jars by heating in a pot of water that is gradually brought to a boil for 10 minutes. (No need to sterlize lids.) Turn off the heat and leave the glasses in the pot until you are ready to use them. They need to be hot when you pour in the jelly later.
- Always wash fruits right before cooking, no earlier. Wash under cold, running water rather than soaking them, especially when it comes to berries. Wash your fruit. Remove stems, skins and pits from fruit; cut into pieces and crush. For berries, remove stems and blossoms and crush. Seedy berries may be put through a sieve or food mill.
Extracting the Fruit Juice
- In your large, heavy, 8- to 10-quart saucepot, add fruit and only the amount of water called for by the recipe. Too much water will require longer time to strain and longer cooking time and not enough water may result in scorching (burning) the fruit.
- Cover, bring fruit juice to a rapid boil, stirring frequently. Reduce heat, cover loosely, and continue cooking, stirring and crushing the fruit until it is soft and the juices are flowing; berries only need a couple minutes and hard fruit like apples may need anywhere from 15 to 30 minutes.
- Suspend a damp jelly and jam strainer or use wet cheesecloth over a colander or sieve. Pour the cooked fruit into the bag or cheesecloth and strain over a large bowl. For the best results, let it strain (drip) without forcing the liquid. This may take 2 hours or longer. If you squeeze the bag to extract the juice faster, you’ll still get good juice, but it will be cloudy, and so will your jelly. Tip: If the yield of juice is slightly less than the recipe quantity required, add ½ cup boiling water to the remailing fruit pulp to extract additional juice or you can use unsweetened apple or white grape juice to extend the quantity.
Cooking the Jelly
- In a large, deep stainless-steel saucepan, place the fruit juice and lemon juice, if needed, per recipe directions. If adding pectin, whisk the pectin into the fruit juice until it is dissolved and bring to a boil over high heat, stirring frequently.
- Add the sugar all at once, stirring until sugar dissolves and return to a rolling boil. Tip: Low-pectin fruit jelly can be made by combining the low-pectin juice with home-made apple juice—proportioned 1:1, plus ⅔ cup of sugar for each cup of juice. If you are using blueberries or strawberries, add 1 tablespoon lemon juice for every 2 cups of jelly juice.
- Continue boiling the jelly and stirring for a clear-finished product. As the fruit mixture begins to thicken, stir frequently to prevent sticking and scorching. Tip: From the combination of juice, acid, pectin, and sugar to the temperature you heat your jelly at, everything has to be exact. In general, when no added pectin is used, the jelly stage is reached at 8°F above the boiling point of water. The boiling point for water is about 212°F at 1,000 feet or less. You can use a candy thermometer to determine the actual temperature at which water boils in your own kitchen.
- If not adding pectin, you need to test whether or not your jelly has jelled. Use a candy thermometer, but if you don’t have one, take a spoonful of the juice five minutes after you’ve added the sugar, let it cool for a minute, then tip the spoon back into the kettle. If the juice runs together at the edge and “sheets” off the spoon, then you’re ready to pour. Another test we like is the freezer test. Pour a small amount of boiling jelly on a plate, and put it in the freezing compartment of a refrigerator for a few minutes. If the mixture jells, it should be done. During the test, the rest of the jelly mixture should be removed from the heat. (Note: If you’re adding extra pectin, you don’t need to test for jell.)
- Remove your hot sterilized jelly jars from the pot. Drain the glasses and place them on a level surface.
- Fruit juice cooked with sugar produces considerable foam or scum. Skim scum off quickly before ladling the hot jelly into the hot jars. Tip: Alternately, you may add ½ teaspoon of butter or margarine when adding the sugar and before bringing to a boil. Do not add more butter or it will interfere with the jelling.
- As you ladle the jelly into the jars, leave a ¼-inch headspace. Be careful not to spill any over the sides. If you do, wipe it off before you put the lids on.
- After you pour the jelly, stir it gently around the sides of the jars once with a plastic wand or spatula to eliminate air bubbles.
- Place lids that have been washed and dried on the jars. Add screw bands and tighten until finger-tip tight.
Processing the Filled Jars for Storage
In order to keep homemade jelly beyond a few weeks, the filled jars must be processed using water-bath canning.
- Place jars in a boiling water bath canner, making sure the jars are completely covered with water (1 to 2 inches above the jars).
- Cover with lid and bring water back to boil, processing half-pints and 8 oz jelly jars for 10 minutes.
- When time is up, turn off the heat, remove the lid—venting the steam away from you—and wait 5 minutes.
- Remove jars to a wooden trivet or kitchen towel on the counter and let sit for 12–24 hours. Remove the screw bands and check the seal by depressing gently the center of the lid. Store only jars that have sealed. If the lid wobbles, refrigerate the jelly and enjoy within a few weeks!
