Grocery store yogurt is sold by weight; 32 oz and 64 oz tubs. Yogurt recipes are usually given by volume; 1 quart (4 cups or 32 fl oz). So in order to decide if it's worth it to make my own yogurt I need to translate and get everything in the same units. According to All Recipes, 1 cup of yogurt weighs 8.6 oz. So a 32 oz tub contains about 3.75 cups or 29.75 fl oz of yogurt.

Today I paid $1.99 for a 32 oz tub, which was 6.2 cents/oz or 6.7 cents/fl oz.  My recipe for yogurt calls for 4 cups (32 fl oz) of milk plus 2 tablespoons of yogurt to make 1 quart (32 fl oz) of yogurt. At $4/gallon, my milk costs 3.125 cents/fl oz. That means my fancy local milk is half the price of national brand plain yogurt by volume. Even assuming some loss of volume in going from milk to yogurt it's still much more cost effective to make my own yogurt. I'll definitely be making my own yogurt in the future.

I haven't been doing a lot of the cooking lately, but I did a couple of frivolous things today.

First I made yogurt. After scouring the internet I found the simplest method possible. Heat 4 cups of milk to 180F, drop it back down to just below 120F and stir in 2 Tbsp of yogurt. Pop that in a clean quart canning jar and put it in a small cooler with a companion jar of hot water. It should be ready later this evening. I did this with Sassy Cow milk, which comes from about 10 miles from my house.

This evening I went outside to tell Drew that we're in a tornado watch zone. Not a big deal, since as I was taught, it's the R in Warning that means Run. A watch just means "Clean up the back yard so that the sheets of foam board insulation don't end up down the street". As I was out there I noticed the dandelion greens. I came back in for a bowl and then picked a whole salad spinner full of dandelion greens. Tomorrow night I'll steam them and serve them with lentils and barley. Tasty and easy springtime dinner!

I've been buying my eggs from a vendor at the Farmer's Market for over a year now. We're very happy with the quality of the eggs and knowing that the chickens are treated well. But sometimes you just can't get to the farmer's market for eggs. That's where this article comes in.

What does the label on the egg carton mean?

It turns out that the organic eggs at the giant grocery store are American Humane Certified which isn't perfect but is sufficient when I'm out of eggs.

Summer is coming to an end. Our tomatoes and tomatillos are going berserk. So last night I canned the first 3 quarts of our tomatoes. There are another 2 quarts of tomato juice & bits; those will wait until I have pint jars. Putting Food By says not to can quarts of juice.

I also bought pickling cucumbers last week. I must remember to make pickles this weekend. I picked most of the kale from the garden. That needs blanching and freezing.

It's interesting, the actual canning and freezing is easy. It's the prep that takes forever. Like peeling 15 pounds of tomatoes (drop 5 in boiling water for 3 minutes, put into cold water bath, put 5 more in, peel the tomatoes in the cold water, repeat), and then chopping them. Once they were in the cookpot (PFB said to boil for 5 minutes before packing) it was easy.

If you're looking for a resource for food preservation and you have a scientific bent, definitely look at Putting Food By. There are nice scientific explanations of why to do X, Y, and Z. I feel a little safer following these instructions since I understand why to do what.

I've just signed up for the Wisconsin Eat Local Challenge. The goal is to spend 10% of your grocery budget for 10 days on local foods. It should be pretty easy. As it is I get all my vegetables from the CSA or farmer's market and my dairy and eggs are locally sourced. That means that my trucked in food is starches (rice, tortillas, flour and pasta) and staples (sauces, oil, baking supplies, canned tomatoes).

As the tomatoes get going I'll can some for the winter. I'll also freeze the green beans from the CSA and turn our tomatillos into sauce for the winter (freeze or can, I'm not sure).
