3, 4, or 5 usually being sufficient. Otherwise, the canning
process, including the length of time for processing, does not differ
materially from that just given for sweet soft fruits.
In the case of strawberries, those which are of medium size and rather
dark in color are best for canning; in fact, very large, light-colored
strawberries will shrink more than any other kind. The berries are
washed in the same way as other berries, but they should not be allowed
to stand in water for any length of time, because this will tend to make
them soft and mushy. Strawberries must be stemmed after they are washed,
and for this purpose a strawberry huller should be utilized. Such a
device, which is shown in Fig. 1, permits the stems to be removed
without crushing the berries and soiling the fingers.
In preparing currants for canning, the procedure is the same as for the
fruits already mentioned; and the same thing is true of grapes that are
not to be seeded. If the seeds are to be removed, however, the procedure
up to getting the cans of fruit ready for processing is different, as is
here pointed out. After washing the grapes, squeeze the pulp from the
skins and then cook it in a kettle for a sufficient length of time to
make it soft.
