Today, a guest post from Nancy Klehm, writing to us from Chicago, in the midst of an epic drought and heat wave. Here’s Nancy:
A Drought of Inspiration
Until last week, we were at 12% of our normal precipitation for our eight month growing season. This, plus extreme temperatures, made us delirious when some humidity blew south from Canada and was sticky enough to grab ahold of some clouds and build them until they spilled rain. And yet, the GM soy is limp and the GM corn is dwarfed and tasseling weakly. The effects of which will impact all of us who shop and drive cars.
And frankly, we’ve been spoiled by the drought and heat – it’s always sunny and dry (just like L.A. and Phoenix!) no rain to spoil your bike ride, BBQ, or outdoor gardening. And the biggest benefit: No Mosquitos.

The rough side of our weather is obvious. Due to July temperatures in March immediately followed by appropriate, but ultimately harming coolness, we lost most of our tree fruit production. Local orchardists turned to growing supplemental vegetable crops. There are none or not many apples, Asian pears, peaches, cherries or plums this year. No pawpaws. What we are left with is heat-island city fruit, and shrub fruits of currants, gooseberries, black raspberries, blackberries, strawberries, elderberries, wild plums. But it is a okay pear year and I will be getting some American wild persimmons. Hubba Hubba.
And so I concentrate on the fact that this climate is prime to dry just about anything – and to fermenting my year’s supply of tempeh and the koji needed for my fall miso and tamari production.
I like to ferment passively, using the wide range of microclimates of my non air conditioned house. I have no uniform temperature control in my house, in spite of having a thermostat and I like it that way. It makes for a broad spectrum of air humidity and temperature that allows me to situate the different fermenting processes appropriately.
Tempeh: a passive ferment
Tempeh is a relatively quick ferment of 8-12 hours when temps are between 85-95 degrees. Tempeh is dang tasty. It is basically beans partially digested by and knit together with mold or as some would prefer to say, a ‘mushroom’ called Rhizopus oligosporus. Because it is fermented, it is a more highly nutritious and easily digestible soy form then is tofu or soy milk or the beans themselves. It is easy enough to make and relatively easy to jump the spore onto other substrates, i.e. experimental combinations of grains and legumes. The tempeh dance is easy enough and even easier to riff off of:
Soak selected beans and grains 24 or more hours for a primary fermentation, then under cook them (soft enough to bite, but not soft enough to enjoyably eat), drain and dry the beans/grains of residual moisture with a towel and allow to cool. Toss with the tempeh starter and a touch of vinegar and pack ½”-3/4” thick into ziplock bags that you have pierced holes through with a fork. Place in a dark place and allow the summer heat to do its job. Depending on atmospheric temps, this will take anywhere between 12 and 24 hours.
The tempeh is done when it is white and caked together with mold, maybe with some grayish or dark areas near the fork holes where the mold has started sporulation. Use or freeze immediately or the spore will keep running. Delish!
Next time: Koji.
