Homemade Yogurt
by Crystal Miller
Yogurt takes a little bit of time to make. Not actual working
time but time for it to sit and culture. Yogurt is a cultured
product, much like cheese. It is a very easy and economical to
make.
Before you begin there are a few things to make sure you have on
hand and a few things to know and understand about the process.
Most of what you need you will be able to find in the grocery
store.
You need to begin with starter yogurt. Starter yogurt is yogurt
that has been made with active live cultures; this is the
friendly bacteria that will turn your milk into yogurt. You can
buy a small container of yogurt at the grocery to use for this
purpose. Make sure that the container says Made with live
cultures or something of this nature. You want to buy plain
yogurt, not flavored. Each time you make yogurt you will need
some starter. You can use your own starter, but over time it
looses its potency and your yogurt will not turn out. So I always
begin with store bought yogurt. You can freeze your starter
yogurt in ice cube trays so that it is convenient to have on
hand.
As far as tools for making yogurt go, you will need a
thermometer. A candy thermometer bought from the grocery store
will work just fine. You will need a large pot to heat up your
milk and then something to incubate your yogurt for about 12
hours. The temperature of the yogurt must stay between 90 and 110
degrees during this incubation time.
There are a variety of ways of maintaining this temperature. If
you have a gas stove, putting your yogurt in the stove and
leaving the pilot light on may be enough. Make sure you have a
thermometer in the oven so you can keep an eye on the
temperatures. If you have a stove that you can set at around 100
degrees, this works also. Another method that works is to use a
small styrofoam ice chest. While you are making the yogurt fill
up the ice chest with hot tap water. Right before you set the
jars in the ice chest empty the water, place filled jars in the
ice chest, and fill with 110 degree water up to the bottom edge
of the lids. Put the cover on and place a blanket over this.
After about 4 hours check to make sure the water is still the
right temperature (between 90-110 degrees). If the water is
cooling down, dump half of it out and replace with 110 degree
water and cover again. Check every 1 1/2 hours or so to make sure
the water is staying warm. If the temperature of your yogurt gets
to high or to low then it will kill the culture. So it is
important that during the incubation period that your temperature
stays between 90 and 110 degrees.
