In Praise of Poultry Staples

poultrystaple

A neighborhood chicken tragedy involving a coyote reminded me of an important coop building detail worth repeating:

Use galvanized poultry staples not staple gun staples to secure your 1/2 inch hardware cloth (and don’t use chicken wire–the gaps are so big that raccoons can reach right in and eat your poulrty through the wire). Poultry staples are nailed in with a hammer. I use a pair of needle nose pliers to hold the staple while I hammer it home. Regular staples rust and are not strong enough to keep out predators.

A last detail is to periodically inspect coops for possible weak points. I’m overdue for this. I’ve scared away a coyote twice now this year in our backyard (during the day!).

What’s the Best Solar Food Dryer?

Dehydration is a great way to put up food. Second to freezing, it’s the best way to persevere nutrition without adding sugar or salt. And if you use the power of the sun, you won’t need to spend any money on electricity.

In a desert climate you can just put your food out on screened trays. But just a bit of humidity in the air makes this approach risky. Food can spoil before enough moisture is removed. That’s why you should build a solar food dryer.

There are two basic designs for solar food dryers: direct and indirect. Direct dryers are just a box with a piece of glass on the top. Indirect dryers use a box to collect the heat of the sun and then, thanks to the fact that hot air rises, take that heat up into an enclosed box that contains the food you want to dry.

Which design works best? Dennis Scanlin, Coordinator of the Appropriate Technology Program and Professor of Technology at Appalachian State University in Boone, North Carolina has been studying solar food dryer technology for decades.  According to Scanlin, indirect drying is the way to go. Scanlin tested three dryers, the Appalachian Solar Food Dryer (an indirect dryer that he invented) against a direct dryer developed by the Brace Research Institute and the Poisson indirect dryer. In an article in Permaculture Activist, “Evaluating Solar Food Dryers: Stocking Up with Solar Power,” Scanlin says,

The Appalachian indirect dryer produced higher temperatures than the other two dryers and also removed more moisture from the tomatoes drying inside each day. In one test, the Appalachian dryer removed 32 oz. (0.95 L) of water during ta day, while the Brace direct dryer removed only 20 oz/ (0.59 L), and the Poisson dryer only 15 oz. (0.44 L). The Appalachian dryer was able to remove as much as 3.73 lb. (1.69 kg) of water in a single sunny day from tomatoes drying inside.

Scanlin also notes that direct dryers degrade the quality of the food and possibly nutritional value due to direct UV exposure.

Our Appalachian Food Dryer, badly in need of a paint job.

We built a Appalachian Dryer several years ago and it works great. You do need to remember to bring in the food at night to prevent rehydration and spoilage (for some reason I often flake out and forget to bring in the food). For awhile I had an electric Excalibur Dehydrator on loan and it’s a lot more convenient. But, of course, it uses electricity and makes a lot of noise.

Since I built my Appalachian Dryer Scanlin has decided that it’s not necessary to use insulation. This makes the project even simpler. For just around $200 worth of materials you can easily make an Appalachian Dryer out of plywood nails and screws.

You can find plans for Scanlin’s dryer here.

Making Tofu From Scratch at the Institute of Domestic Technology

IMG_0163

Around once a month I teach a bread class at the one of a kind Institute of Domestic Technology, founded by our friend Joseph Shuldiner. The IDT is not your usual cooking school and its offerings are difficult to define succinctly. If I had to take a stab at explaining what the IDT does it would be that it teaches things worth doing from scratch that most people haven’t attempted since the pre-Betty Crocker era: cheesemaking, home coffee roasting, bacon curing, bread baking, jam and exotic projects like making your own nocino and toothpaste.

One of the perks of teaching at the IDT is getting to sit in on some of the other classes. The coffee roasting class changed my life. Now, every morning, I look forward to fresh coffee I roasted myself in a Whirley-Pop Popcorn maker. This past weekend I sat in a new IDT class taught by author Andrea Nguyen on how to make tofu from scratch.

The Other Kind of Fencing

kellyfencing2

That’s Mrs. Homegrown on the left back in 2005.

It was with great sadness that we got the news of the passing of our fencing coach Amy Fortune in April. Both Kelly and I were lucky to have taken many lessons with Amy. She was one of those teachers that bring unexpected and valuable life lessons far beyond the topic at hand. She was patient, encouraging and always positive. We miss her very much and send our condolences to her husband Geoff, also an amazing fencing coach.

When I walked into my first lesson with Amy, many years ago, she said that if she were to build a fencing robot from scratch it would look like me: tall and gangly. Unfortunately, what Amy did not know is that I lacked even a shred of natural athletic talent. Which is precisely why I’ve become obsessed with this sport. It offers me a chance to work on things I’m terrible at: strategy, mindfulness, flexibility, speed and endurance.
