Yes, it sounds dangerous and
the potential for messes seems highly likely, but you'll
be surprised at the good, "clean" fun you'll
enjoy when you make ice cream.This recipe is enough for
one person to make a dish!
- 1/2 cup milk
- 1/2 teaspoon vanilla
- 1 tablespoon sugar
- 4 cups crushed ice
- 4 tablespoons salt
- 2 quart size Zip-loc
bags
- 1 gallon size Zip-loc
freezer bag
- a hand towel or gloves
to keep fingers from freezing as well!
Mix the milk, vanilla and
sugar together in one of the quart size bags. Seal
tightly, allowing as little air to remain in the bag as
possible. Too much air left inside may force the bag open
during shaking. Place this bag inside the other quart size
bag, again leaving as ittle air inside as possible and
sealing well. By double-bagging, the risk of salt and ice
leaking into the ice cream is minimized. Put the two bags
inside the gallon size bag and fill the bag with ice, then
sprinkle salt on top. Again let all the air escape and
seal the bag. Wrap the bag in the towel or put your gloves
on, and shake and massage the bag, making sure the ice
surrounds the cream mixture. Five to eight minutes is
adequate time for the mixture to freeze into ice cream.
Tips:
Freezer bags work best
because they are thicker and less likely to develop small
holes, allowing the bags to leak. You can get away with
using regular Zip-loc bags for the smaller quart sizes,
because you are double-bagging.Especially if you plan to
do this indoors, I strongly recommend using gallon size
freezer bags.
Here are some interesting
tidbits:
What does the salt do? Just
like we use salt on icy roads in the winter, salt mixed
with ice in this case also causes the ice to melt. When
salt comes into contact with ice, the freezing point of
the ice is lowered. Water will normally freeze at 32
degrees F. A 10% salt solution freezes at 20 degrees F,
and a 20% solution freezes at 2 degrees F. By lowering the
temperature at which ice is frozen, we are able to create
an environment in which the milk mixture can freeze at a
temperature below 32 degrees F into icecream.
Who invented ice cream?
Legend has it that the
Roman emperor, Nero, discovered ice cream. Runners brought
snow from the mountains to make the first ice cream. In
1846, Nancy Johnson invented the hand-cranked ice cream
churn and ice cream surged in popularity. Then, in 1904,
ice cream cones were invented at the St. Louis World
Exposition. An ice cream vendor ran out of dishes and
improvised by rolling up some waffles to make cones.
