Yogurt 101

I'm doing a little experiment today, not only in the form of this blog post as a pattern plus recipe but also an experiment in microbiology--culturing milk to make yogurt.

It's worth making your own yogurt for two reasons: (1) it is fairly easy and inexpensive to make yogurt at home and (2) yogurt has a number of health benefits. Milk becomes yogurt by encouraging friendly microbes to multiply and breakdown lactose and other molecules in milk. To do this, you simply combine a small amount of yogurt (from the previous batch or from store-bought yogurt) with milk and heat everything up to encourage the microbes to grow.


So how does this all relate to knitting? Well, the yogurt/milk mixture needs to be kept warm for several hours during the culturing process. Wrapping a towel around the culturing container is one way to keep the liquid warm, but as a knitter I find the idea of using a jar cozy to be much more appealing. Both in terms of the cozy-factor and the cute-factor.


My Yogurt 101 lesson goes through both how to make yogurt in a standard one-quart canning jar as well as how to knit a cozy for that jar to help with the culturing process. Do try this at home!

Making the Yogurt
Using directions from The Curious Cook

Ingredients:
1 quart whole milk
2 Tbsp store-bought or homemade yogurt

Recipe:

Slowly warm milk to just below boiling (180-190 F), being careful not to scorch it. Allow the milk to cool to 115-120 F. Whisk in yogurt and pour mixture into warm one-quart canning jar. Cover jar with cozy and let sit undisturbed for about 4 hours or until the yogurt sets up. If you want your yogurt to be thicker, strain it through a cheesecloth. Store yogurt in the fridge.

Making the Jar Cozy


Requirements:
- 75 yards Cascade Eco Wool (or another bulky wool yarn)
- Set of five US size 10 [6 mm] dpns

Gauge:
15.5 stitches and 22 rows = 4 inches in stockinette

Pattern:
Cast-on 48 stitches. Divide stitches evenly over 4 needles (12 stitches per needle).
Join to work in the round, bring careful not to twist.

Work in [K1, P1] rib for 2 inches.

Work in stockinette (all knit) for 5 inches.

Decrease for bottom as follows;
Work [K to last 2 stitches on needle, K2tog] a total of 4 times.
Repeat this row 9 more times until 8 stitches remain.

Break yarn and pull end through remaining stitches.
Weave in ends, put jar into cozy and make yogurt!
