Steam-extracted fruit juice

steam juicer juice · juice for jelly and syrup

Loading ratings…

Clear juice that a stacked steam juicer draws out of ripe fruit by steam alone, without crushing it. It is the base for jelly, syrup or cordial and still needs its own keeping step.

Juice without crushing

A steam juicer is three stacked parts: a water pan on the stove, a collector with a central cone and a clamped hose, and a perforated basket with a lid. Water boils in the bottom pan, steam rises through the fruit in the basket, and the juice runs down the cone into the collector and out through the hose. Oregon State's extension page for its library-of-things steam juicer describes the parts and the basic use, and its videos show the routine with berries.

Because nothing is pressed, the juice comes out clear and the pits and pulp stay in the basket. The juice is hot as it drains, and the juicer maker's instructions govern assembly. The Oregon State video notes that marbles in the bottom pan rattle when the water runs low.

Steaming the fruit

Berries are rinsed and put in the basket; peeling is not needed. The Oregon State demonstration steams for 30 minutes, drains the juice, and steams for another 15 minutes if the fruit still holds juice. Utah State gives half an hour to an hour depending on the load.

Chokecherries get their own rule. Utah State's peer-reviewed fact sheet says to use only ripe fruit with stems and leaves removed and not to crush the pits, because crushed pits can release cyanide. Its stovetop alternative simmers 4 cups of cleaned chokecherries with 1 cup of water until very tender, then drips the mash through a damp jelly bag or several layers of cheesecloth without twisting or pressing. The fact sheet gives about 2 cups of juice per pound.

Keeping the juice

The juice is an intermediate. It can be used at once for jelly or syrup, refrigerated, or frozen. The sources give no refrigerated keeping time for fresh steam juice, so the cook should use it soon and freeze the rest. Frozen juice is packed with 2-inch headspace in glass or plastic jars.

Shelf storage needs a tested process. Oregon State's juice bulletin gives boiling-water bath times for pints and quarts of fruit juice and for half-gallon jars, by elevation. Steam extraction itself is not a preservation step. An optional berry syrup, from the USDA recipe shown in the Oregon State video, combines 5 cups of the juice with 6¾ cups of sugar and is processed for 10 minutes once the water boils, with the elevation adjustment the source gives.

Method

Risks and precautions · Elevated risk
Cyanogenic compounds in chokecherry pits, stems and leaves

Crushed chokecherry pits can release cyanide, so the pits must stay whole and the stems and leaves must be removed.

Hazard source
Hot juice and steam

The juice drains hot from the hose of the steam juicer.

Hazard source

Use only ripe chokecherries, with leaves and stems removed, and do not crush the pits.

Control source

Process juice for shelf storage in a boiling-water bath, using the Oregon State schedule for the jar size and elevation.

Control source

Steam extraction is not a preservation process.

Shelf-stable juice needs the tested water-bath process; fresh juice is refrigerated or frozen.

  1. Fill the bottom pan of the steam juicer with a few inches of water and a handful of marbles, set it on the stove on high and bring it to a boil.
  2. Put the rinsed berries, or other washed fruit with peeling not needed, in the top basket. Stack the collector on the water pan and the basket on the collector, add the lid, check that the hose is clamped and place a bowl under it.
  3. Steam for 30 minutes, then carefully drain the hot juice into a bowl. If the fruit still holds juice, steam for 15 minutes more and drain again. The Utah State demonstration gives half an hour to an hour, depending on the load.
  4. Chokecherries: use only ripe fruit with leaves and stems removed, and do not crush the pits. The steam juicer leaves pits and pulp in the basket (Utah State).
  5. Stovetop alternative (Utah State): simmer 4 cups of cleaned chokecherries with 1 cup of water over low heat until very tender, stirring occasionally and without crushing the seeds. Pour into a damp jelly bag or several layers of cheesecloth in a colander and let it drip without twisting or pressing.
  6. Use the juice at once for jelly or syrup, refrigerate it, freeze it, or can it by a tested method.
  7. To can the juice (Oregon State SP 50-455): if it has cooled, heat it to simmering. Pour into hot sterile jars with ¼-inch headspace and process in a boiling-water bath for 5 minutes for pints and quarts and 10 minutes for half-gallons at 0 to 1,000 ft; at 1,001 to 6,000 ft, 10 minutes for pints and quarts and 15 minutes for half-gallons. To freeze, cool the juice and pack it with 2-inch headspace in glass or plastic jars.
  8. Optional berry syrup (the USDA recipe as demonstrated by Oregon State's video): combine 5 cups of steamed juice with 6¾ cups of sugar, simmer for 1 minute, remove from the heat and skim. Fill hot jars with ½-inch headspace, remove bubbles, wipe the rims and fit fingertip-tight bands. Process for 10 minutes once the water boils, adjusting for elevations over 1,000 ft. Rest the jars for 5 minutes with the lid off before removing them.
