A household freezer holds food in a frozen state for storage and selected texture or separation work; its batch-storage role differs from industrial equipment that freezes individual pieces separately.

steam juicer juice · juice for jelly and syrup
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.

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.
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.
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.
Current extension material describes the steam juicer as a library-of-things item. No dated history was researched.
Scaling: source batch only
Crushed chokecherry pits can release cyanide, so the pits must stay whole and the stems and leaves must be removed.
Hazard sourceThe juice drains hot from the hose of the steam juicer.
Hazard sourceUse only ripe chokecherries, with leaves and stems removed, and do not crush the pits.
Control sourceProcess juice for shelf storage in a boiling-water bath, using the Oregon State schedule for the jar size and elevation.
Control sourceSteam extraction is not a preservation process.
Shelf-stable juice needs the tested water-bath process; fresh juice is refrigerated or frozen.
