so under no circumstances must it be used. But with pineapples the
object of blanching is primarily to soften the hard fiber, so there is
no objection to using the blanching water.

After the pineapple has been in the covered kettle of boiling water
for five minutes, it is held under cold water until cool enough to
handle. Never let it soak in cold water, as that will impair its
delicate flavor. After this it is packed into hot sterilized jars.
Rubber rings are put on the jars, the covers are put in place--not
tight--and the jars are put in the canner.

Pineapple is sterilized for thirty minutes in a hot-water-bath outfit;
thirty minutes in a condensed steam outfit; twenty-five minutes in the
water-seal; twenty-five minutes in the steam pressure under five
pounds of steam, and eighteen minutes in the pressure cooker under ten
pounds of pressure. At the end of the sterilizing period the jars are
removed, the covers completely tightened and the joints carefully
tested for leakage.

A thin or medium-thin sirup is best for pineapples. Measure the
blanching water and to every two cups of it add three cups of sugar.
If you wish the sirup thin heat until the sugar is dissolved. If
medium-thin sirup is desired, boil it about four minutes or until it
begins to be sirupy.
