Kefir

If you haven't ever tried kefir you really should.  It is so good for you, inexpensive, and easy to make.  Kefir is full of probiotics, which are great for your health.  My family has it for breakfast every other morning.  It is a nice filling and tasty drink.  When you research it online it's impressive the benefits that many people claim they've had drinking it.  This shouldn't be too surprising since many physical problems can be connected to our diets, and probiotics help to keep our digestive system cleaner.  I noticed since we've been drinking it my kids don't get the stomach flu as often, and when they do they don't usually get as sick as they used to.  Many people who are lactose intolerent like to drink it because the kefir grains pre-digest everything making it easier on the digestive system.  It is important to know that many people when they first start drinking it have a little diarrhea or sometimes upset stomaches.  Everyone I've known who has had these problems find it usually lasts no more than a week and then they begin to see some of the positive effects of probiotics. 
In order to make kefir you must have kefir grains.  These are seen in the picture in the jar of water.  In water these grains (or live and active cultures) are dormant.  This is how I store the extra grains that are produced in the process of making kefir.  I store them so that I can have them on hand to give away to friends or family who are interested in trying them.  You can buy some grains online that have usually been frozen. When you start with previously frozen grains, you might often find that the first few times making it, the kefir doesn't ferment as fast or as well.  To make the kefir you put the grains in your milk and leave on the counter for 24-48 hours.  It's important to use a container that isn't metal or that has no metal that will touch the kefir or the grains.  The metal interferes with the process.  I use a half gallon mason jar.  For my half gallon mason jar I use about 3 Tbsp of kefir grains.  They should grow and produce more as you use them.  If you order kefir grains online you will usually only recieve enough for 1-2 cups of milk.  If you need more than you can make it until you've produced enough grains for the amount you need to make.  After it's sat on the counter it should become kind of thick like yogurt and smell like yeast.  In order to be able to continue to make some you need to drain your kefir through a plastic colander so you can preserve your grains for more use.  When I fix my kefir I put my half gallon of kefir in my blender and add a couple of handfuls of frozen fruit, a little vanilla, and some type of sweetner.  My kids love it and drink it up really well, they usually like it with a little toast.  It's a great way to start the day.
