How do you make jelly from fruit juice?

Jelly is fruit juice boiled with sugar until it gels. You cook the fruit, let the juice drip clear through a jelly bag, measure it, then either boil it with sugar to the set point (for high-pectin fruits such as apples, crabapples and grapes) or boil it with commercial pectin and sugar for a timed minute (for any fruit) [1][2]. USDA's no-pectin method allows no more than 6 to 8 cups of juice at a time, 1/4 inch headspace and a short boiling water process [1]. This page walks through both routes from juice to sealed jar, and explains why jelly is less forgiving than jam.

Two routes, one decision

Pick the route by your fruit. High-pectin fruits and why they set on their own are explained on where the pectin is, and the trade-offs between the routes on added pectin or long boil.

Before you start

• Juice. Have your juice extracted, strained and measured. One pound of fruit should give at least 1 cup of clear juice [1]. Extraction is the step that decides how clear your jelly is; it has its own page, extracting juice for jelly.
• Pan. Use a large, flat-bottomed kettle of 8 to 10 quarts so the jelly can boil hard without boiling over [3]. Jelly foams and climbs the pan at a full rolling boil.
• Jars. Half-pint jars are the usual size for jelly. Have them washed, hot and ready, with new lids, and decide now whether you will sterilize them, because that decides your processing time (see the canning step below).
• Canner. Fill and heat the boiling water canner while the juice cooks.
• Thermometer. For the no-pectin route, a calibrated thermometer makes the set point easy to see.

Jelly without added pectin, step by step

This is USDA's method, as published by NCHFP [1].

1. Measure the juice, sugar and lemon juice for your fruit from the table below into the kettle. Work with no more than 6 to 8 cups of juice at a time.
2. Heat to boiling, stirring until the sugar dissolves.
3. Boil over high heat to the jellying point. Do not stir it down; let it boil hard.
4. Test for doneness by temperature or with the sheet test:
   • Temperature: 220°F at sea level, 218°F at 1,000 feet, 216°F at 2,000 feet, 214°F at 3,000 feet and so on, about 2°F lower per 1,000 feet [1]. The full table, and the 8°F-above-boiling method that corrects for your own thermometer, are on the temperature test.
   • Sheet test: dip a cool metal spoon into the boiling jelly, lift it about 12 inches above the pan and turn it so the syrup runs off the side. It is done when two drops flow together and sheet off the edge [1]. See the spoon or sheet test.
5. Remove from the heat and quickly skim off the foam [1].
6. Fill the jars at once, with a ladle or measuring cup and a wide-mouth funnel, leaving 1/4 inch headspace [1]. Jelly that stands before filling, or is poured too slowly, can turn cloudy [4].
7. Wipe the rims, put on lids and bands, and process (see below).

USDA proportions for no-pectin jelly

Source: USDA Guide 7, as published by NCHFP [1]. The water and simmer columns are for extracting the juice. Colorado State's jelly sheet adds quince (3 1/2 pounds fruit, 7 cups water, 25 minutes) and red currants (2 1/2 quarts, 2 1/2 cups water, about 10 minutes) to the extraction list [3].

Jelly with added pectin, step by step

For pectin jelly, the recipe is the method. USDA's general steps are: bring the juice (with pectin or sugar, depending on the pectin form) to a boil, add the other, bring to a full rolling boil, boil hard for 1 minute while stirring, skim, fill with 1/4 inch headspace, wipe rims, put on lids and process [2]. Liquid and powdered pectin go in at different points, so follow the package directions or a recipe written for your form [2]; the reasons are on liquid or powdered pectin.

Here is how one USDA recipe lays it out, Guide 7's grape-plum jelly with powdered pectin, which makes about 10 half-pints [2]:

1. Wash and pit 3 1/2 pounds of ripe plums without peeling. Crush the plums and 3 pounds of ripe Concord grapes, one layer at a time, with 1 cup of water.
2. Bring to a boil, cover and simmer 10 minutes. Strain through a jelly bag or cheesecloth. Measure the sugar and set it aside.
3. Combine 6 1/2 cups of the juice with 1/2 teaspoon butter (optional) and 1 box (1 3/4 ounces) of powdered pectin, and bring to a hard boil.
4. Add 8 1/2 cups of sugar, return to a full rolling boil and boil hard for 1 minute.
5. Skim, fill sterile jars with 1/4 inch headspace and process as below.

The butter is there to reduce foam. USDA notes it may cause an off flavor in long storage [2]; skimming does the same job without it. Foam and the butter question are covered on foam: skim it or add butter?.

A full rolling boil is one that "cannot be stirred down" [5]. Start timing the minute only when you reach it.

Processing the jars

USDA processes jelly in half-pint or pint jars in a boiling water canner for 5 minutes at 0 to 1,000 feet, 10 minutes at 1,001 to 6,000 feet and 15 minutes above 6,000 feet, in jars that were sterilized first [1]. If you did not sterilize your jars, NCHFP says they need a full 10 minute process plus any altitude adjustment instead [7]. Use the processing chart from the same source as your recipe and never mix one source's base time with another's altitude steps; both charts are on how long to process jam.

After processing, let the jars cool upright and undisturbed. Penn State advises waiting 12 hours before moving them, because moving jars weakens the forming gel [5]. Checking seals is on cooling jars and checking the seal.

Why jelly is less forgiving than jam

Jam hides small mistakes; jelly shows them. Five reasons:

1. There is no fruit to carry a soft set. A slightly loose jam is still spreadable because the fruit pieces give it body. A slightly loose jelly is syrup.
2. Clarity is part of the product. Squeezing the jelly bag, green fruit, slow pouring or letting the jelly stand before filling all cloud it [4]. None of these matter in jam.
3. Measurements are tighter. Juice and sugar go in by exact volume. Too much water at extraction, or the wrong sugar proportion, gives a soft jelly [4]; a heaping cup of sugar can make it too firm [5].
4. Overcooking shows quickly. Overcooking the juice while extracting it, or the jelly itself, damages the pectin [6] or makes it stiff and dark [4].
5. Batch size matters more. USDA caps no-pectin jelly at 6 to 8 cups of juice [1], and NCHFP lists too large a batch among the causes of soft jelly [4].

If a jelly is soft after a day or two, wait before deciding. NCHFP lists "insufficient time before using" as a cause of soft jelly [4], and Penn State says some jellies take three weeks or more to set [5]. If it never firms, the USDA remake is on jam that didn't set, and cloudy jelly is diagnosed on cloudy jelly.

Getting juice that makes clear jelly

Most of what makes a jelly beautiful happens before the sugar goes in. Extracting juice for jelly covers cooking, dripping, steam juicers, how much fruit to buy and freezing juice for later.
