Blanched
Almonds.
Put
the
almonds
into
cold
water,
and
heat
them
slowly
to
scalding;
then
take
them
out
and
peel
them
quickly,
throwing
them
into
cold
water
as
they
are
done.
Dry
them
in
a
cloth
before
serving.

Freezing
without
Ice
or
Acids.
The
use
of
ice
in
cooling
depends
upon
the
fact
of
its
requiring
a
vast
quantity
of
heat
to
convert
it
from
a
solid
into
a
liquid
state,
or
in
other
words,
to
melt
it;
and
the
heat
so
required
is
obtained
from
those
objects
with
which
it
may
be
in
contact.
A
pound
of
ice
requires
nearly
as
much
heat
to
melt
it
as
would
be
sufficient
to
make
a
pound
of
cold
water
boiling
hot;
hence
its
cooling
power
is
extremely
great.
But
ice
does
not
begin
to
melt
until
the
temperature
is
above
the
freezing
point,
and
therefore
it
cannot
be
employed
in
freezing
liquids,
&c.,
but
only
in
cooling
them.
If,
however,
any
substance
is
mixed
with
ice
which
is
capable
of
causing
it
to
melt
more
rapidly,
and
at
a
lower
temperature,
a
still
more
intense
cooling
effect
is
the
result;
such
a
substance
is
common
salt,
and
the
degree
of
cold
produced
by
the
mixture
of
one
part
of
salt
with
two
parts
of
snow
or
pounded
ice
is
greater
than
thirty
degrees
below
freezing.
