How To Dry Food With the Sun

...ian dryer has screens. I’ve even lost batches I’ve done in an electric dehydrator inside. Thankfully it’s easy to kill larvae by sticking your dried food in the freezer at 0ºF for 48 hours. I’d recommend this step. Further Reading Build It Solar is one of my favorite resources. You can check out a couple of other solar dehydrator designs that are variations on the ones above on their Solar Cooking, Food Drying, Solar Still...

Making Salves, Lip Balms & etc.: Close of the Calendula Series

My calendula after-bath salve. The camera refuses to capture the deep butter yellow color On Saturday, as a part of this long series on Calendula (here, here and here), I posted about infusing oil with herbs. If you’ve got some herb infused oil, you can make that into a medicinal salve or balm. Salve is nothing but oil thickened by the addition of wax. I prefer beeswax salves, though there are vegan alternatives, like candelil...

How to Make Stock

...can add spicy stuff to your stock if you want spicy stock and have a plan for what you’re going to do with it. If you were preparing stock for a Thai soup, for instance, you might start with a stock made with lemongrass or ginger. Otherwise, I’d skip adding the strong flavors until you’re actually cooking with the stock. Keep it simple. Want to work harder? I learned this one from Mark Bittman. To bring out more savory flavors i...

Making Tofu From Scratch at the Institute of Domestic Technology

...ute 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 maki...

Another Panel Solar Cooker

Poyourow demoing her solar cooker design There’s no one size fits all solution when it comes to the world of solar panel cookers. All have their advantages and disadvantages. I got an email from author Joanne Poyourow, leader of the amazing Los Angeles Environmental Change Makers, with a simple and effective design she came up with. Pouyourow’s cooker comes together much faster than the CooKit design that I blogged about earlier th...

Build a Solar Dehydrator

...ral convection (hot air rises). You put the food on screen covered trays in the upper box. With sliced tomatoes it takes about two full days of drying and you have to take the food indoors at night to prevent mold from growing (a minor inconvenience). We built our dehydrator several years ago and have used it each season for tomatoes, figs and for making dried zucchini chips. You can find plans for this “Appalachian Dehydrator”, desi...

CooKit Solar Panel Cooker

I’ve been experimenting with a nice panel solar cooker for the past week and, so far, the results are impressive. Called the CooKit, it was developed in 1994 by a group of engineers and solar cooking enthusiasts associated with Solar Cookers International and based on a design by Roger Bernard. It has a couple of nice features: It produces ample heat to cook rice and simple casseroles. When you fold it up it takes up no more space than a...

How to make a Calendula oil infusion

...ndula Harvesting and drying Calendula Oil infusion is as simple as can be.  Oil infusion is soaking. Think of it like making sun tea. You take a nice clean jar with a good lid, and fill that about half way full of dried herb, top it off with oil, and let that sit in the sun. The resulting oil is medicinal. It can be used straight on the skin, or fashioned into salves and balms. I’m particularly fond of Calendula. As a skin treatment it...

Solar Light Hack

We wanted a solar powered light over our new entrance arbor. The problem is that most of the lights available are just plain ugly. And the solar panels on the cheaper models are usually mounted on the light itself making it impossible to place them in a shady spot. I came up with a simple solution. First, I bought an inexpensive solar light intended to be mounted on a fence. I took it apart and desoldered the LEDs off the circuit board. Nex...
