Milk is not only an amazing food, but can
be made into many other foods as well – butter, ghee, kefir, yoghurt and
thousands of kinds of cheese – and all of them can be made at home. We are
fortunate to be able to use them; in many parts of the world, people cannot
digest milk products, so they tend to be found mostly in Europe, and
occasionally in India or the Middle East.
Butter was deeply important in this part of
the world; for dairying peoples it was the most accessible form of oil, needed
for cooking food and releasing the extra nutrition. Back when people milked
their own cows and goats, they made their own butter with a churn, but you can
do the same thing with a screw-top glass jar or some other sealable container.
First fill the jar one-quarter to one-third
full of cream – a greater proportion than that and it won’t work. People in times past would use whole,
un-homogenized milk, but that’s difficult to find these days, so cream is a
good place to start.
The next step is to shake the jar vigorously
for perhaps 20 minutes ; try putting on some dance music and giving yourself an
aerobic workout, jumping around the house shaking the jar all the while. Don’t
worry if it takes more or less, as it will be fairly clear when butter forms
inside . At first the cream will become, effectively, whipped cream, and if the
jar is more than third full you never get enough agitation to get past this
stage. Eventually, though, you should see the liquid become thin again inside,
with a clump of something in the middle. That clump is your butter, and the
liquid is buttermilk.
To separate them, place a strainer over a
bowl, unscrew the jar and dump the contents into the strainer. You can drink
the buttermilk or use it for making pancakes or any number of other uses – it
should keep for at least a week. The butter you can lift out and put in a bowl to
sweat.
By “sweat” I don’t mean making it hot; in
fact, you could put a few ice cubes in with the butter to keep it cool. It
means that you have to chop, press, squeeze and knead the last of the watery
buttermilk out of the butter, so that it will not go rancid. As in a party
game, you must do this with spoons, touching the butter as little as possible
with your hands – the warmth of your body could melt the butter.
When you are sure the last bit of liquid
has been squeezed out, you have butter. If you like you could use it this way,
as Europeans do, or add salt as English and Irish do to preserve it longer. You
could mix in chopped herbs, like parsley and chives, to spread on bread, or
sage, garlic and rosemary to bake a chicken. Use your imagination.
In warmer countries – or in Ireland in
warmer weather – butter will not keep long in the heat, so before refrigeration
Europeans used clarified butter, and Indians developed ghee. Ghee is
essentially spiced clarified butter, and while there are many variations, you
can make a simple version at home.
First put your butter in a pan on the stove
on very low heat – I put a thin metal plate on our gas stove, and the pan on
top of that, just to dissipate the heat a bit more. The butter will quickly
melt and begin bubbling, which is good – but be very careful not to let it
darken.
The butter should separate into three
layers; a white film on top, the oil layer that is most of the butter, and the
milk remains on the bottom. Only the middle layer is what you want. Early on
you can spoon off the milky bits on top, and spread them on bread if you like. After
that you can add spices, like bay leaves or fenugreek seeds, as the Indians do.
Keep it on very low heat for half-an-hour
to an hour, checking frequently – again, it might take more or less for you.
When there is no more bubbling or hissing, just the oil and the milk deposits
at the bottom, you can strain it through a tea strainer and stop when you get
to the milk deposits. The milk deposits, browned at this point, are still
edible, and are good on popcorn. The rest should be a clear, golden-brown oil
that will keep for months without refrigeration.
Or, you could bury it in a bog if you have
one nearby, as I’ve covered here:
