How do you get clear juice for jelly, and how much fruit do you need?

Plan on about a pound of fruit for every cup of juice: USDA says one pound should give at least 1 cup of clear juice [1]. For the clearest jelly, cook the fruit with a little water until soft, pour it into a damp jelly bag and let the juice drip without pressing; "the clearest jelly comes from juice that has dripped through a jelly bag without pressing or squeezing" [2]. Squeezing gets more juice but clouds the jelly. A steam juicer is a faster alternative that extension services say gives bright, clear juice. This page covers how much fruit to buy, each extraction method, grape crystals and freezing juice for later.

How much fruit to buy

Those two reports work out to about 1.1 cups per pound, close to USDA's rule; they are one household's results. Juicy, ripe fruit gives more; firm or underripe fruit, less. Buy a little extra, because a no-pectin jelly that comes up short on juice cannot be stretched with water without weakening the set: too much water at extraction is one of NCHFP's causes of soft jelly [4].

Method 1: cook, then drip through a jelly bag

This is the standard method, from NCHFP and So Easy to Preserve [2], with USDA's water and cooking times [5].

1. Prepare the fruit

• Prepare the fruit in small batches, enough for one recipe [2].
• Wash the fruit, but "do not remove skins or cores, since the pectin is more concentrated there" [2].
• Wash berries carefully to prevent loss of juice, then drain and remove caps and stems [2].
• For no-pectin jelly, use 1/4 slightly underripe and 3/4 just ripe fruit; with added pectin, all ripe fruit is fine [2].
• Crush soft fruits and berries to start the juice flowing; cut firm fruits into small pieces [2][5].

2. Add water and cook

Colorado State adds quince (3 1/2 pounds with 7 cups water, 25 minutes) and red currants (2 1/2 quarts with 2 1/2 cups water, about 10 minutes, until soft and translucent) [6]. Bring to a boil, then simmer, stirring to prevent scorching [5]. Do not overcook: "excess boiling will destroy the pectin, flavor and color" [2].

3. Drip

1. Dampen the jelly bag or a double layer of cheesecloth [5][6]. A colander first, then the bag, takes the bulk out quickly [5].
2. Pour in the hot fruit and suspend the bag over a bowl. Hang it high enough that the bottom does not sit in the juice [6].
3. Let it drip. This takes several hours [6]; many cooks leave it in a cool place overnight.
4. Do not squeeze. "Pressing or squeezing the bag or cloth will cause cloudy jelly" [5].

If you do press the fruit, through a fruit press or by squeezing the bag, you get more juice but less clarity. Both NCHFP and Colorado State say to restrain pressed juice through a jelly bag or damp cheesecloth before you use it [2][6].

Juice without cooking

NCHFP notes that juicy berries "may be crushed and the juice extracted without heating" [2]. The juice still gets boiled when you make the jelly.

Method 2: a steam juicer

A steam juicer is a stacked pot: water boils in the bottom, steam rises through a middle reservoir into a top basket of fruit, and the juice runs out through a hose that you keep clamped until you are ready to draw it off [7][8].

Safety rules from the two extension sheets [7][8]:

• Check that the hose clamp is closed before heating.
• Watch the water level. Some models have marbles in the base that rattle when the water runs low, so you know to add more.
• Never let the bottom pan boil dry.
• Use gloves, draw off the juice with care, and keep children away. WSU says not to leave the juicer unattended.

Neither Oregon State nor WSU says whether steam juice carries the same pectin as dripped juice. If a no-pectin jelly from steam juice sets soft, make your next batch with an added-pectin recipe. Juice from a steam juicer is not shelf stable as it comes out of the hose; Oregon State says it must be processed by a tested water bath method to keep on the shelf [7].

Grape juice: let the crystals settle

Grape juice carries tartrates, which can crystallize in the finished jelly as gritty, glassy bits. Settle them out before you make the jelly. NCHFP: "allow tartrate crystals to settle out by refrigerating the juice overnight" [4]. Colorado State says to let the juice stand overnight in a cool place and then strain it through two layers of damp cheesecloth [6]. Pour or ladle the clear juice off the sediment. Crystals in finished jelly, and the other causes of crystals, are on crystals in jam and grape jelly.

What clouds juice

NCHFP lists three causes of cloudy jelly: green fruit (starch), imperfect straining of homemade juice, and jelly that stood before it was poured or was poured too slowly [4]. The first two happen here, at extraction. Use mostly ripe fruit, drip rather than squeeze, and restrain anything pressed. Cloudiness affects looks; the full diagnosis is on cloudy jelly.

Freezing juice for later

Extracting juice in summer and making jelly in winter spreads the work, and many makers do it. The sources reviewed for this page give no tested freezing method for jelly juice. Two things are known:

• USDA says commercially frozen juice is too low in pectin for jelly without added pectin, and works with added pectin [1].
• No source reviewed says whether home-frozen juice keeps enough pectin for a long-boil jelly.

So plan to make frozen juice into an added-pectin jelly, where the boxed pectin does the setting. Freeze it in measured amounts for the recipe you intend to use, in freezer-safe jars or containers with room for the juice to expand. Settle and decant grape juice before freezing. Planning a season around frozen fruit and juice is on a year of fruit.

The pulp you have left

Dripped pulp still has fruit in it. It can go into fruit leather, which has its own page, fruit leather from leftover pulp.

From juice to jelly

With clear, measured juice in hand, the rest is cooking. How to make jelly gives USDA's no-pectin method with its sugar and lemon amounts, and the added-pectin method.
