There
are a number of ways to keep cheese in good condition for
long trips, but here's what's worked best for us.
You'll
need a frost-free refrigerator with some space available
and a vacuum bag sealing device.
Cut
a cheese block into slabs about as thick as your thumb.
Separate the slabs with some air space between them on a
cookie sheet or similar, and place them in the middle
shelf of a frost-free refrigerator. The temperatures
inside the fridge will keep the cheese from spoiling
while the fan inside the fridge will remove the moisture
from the cheese, much like a dehydrator does for other
foods. After a day or two, you can remove the cheese and
seal it inside a vacuum sealing device. If you've managed
to removed most of the moisture and oxygen, the cheese
can survive a month or more on a trip.
Covering
the cheese by melting paraffin wax over top can do the
trick if you don't have access to a vacuum sealer, but
the vacuum sealer is better and can be used for a number
of other things as well. Don't scrimp on the vacuum
device, get a good one.
