<em>My friends in college used to call me a Renaissance woman.
I was always doing something crafty, creative, or utilitarian.
I still am. My focus these days, instead of arts and
crafts, has been farming as much of my urban quarter acre as
humanly possible. With my husband, we run <a _mce_href=”” href=””>Dog Island Farm</a>
in the SF Bay Area. We raise chickens, goats, rabbits,
dogs, cats, and a kid. We’re always keeping busy. If I’m not
out in the yard I’m in the kitchen making something from
scratch. Homemade always tastes better!</em>
<p>This is our sixth year growing corn. Our first year we grew the
standard sweet hybrid corn. It did pretty good. The second year we
decided to go with <a _mce_href=”” href=””>heirloom</a>
“dual purpose” corn. When young, it could be eaten right off the cob
and when it was mature it was a flour corn. We ended up waiting too long
to eat most of it early on so we ended up with a bunch of flour corn.
The variety was called <a _mce_href=”″ href=”″>Bloody Butcher</a>
and was a beautiful deep red. We’ve tried other varieties of heirloom
corn but we always come back to this variety because it’s the most
successful for us. We use it for fall decorations and then later strip
the kernels from the cobs. When we first grew it we ended up with a
bucket full of dry corn and I had no idea what to do with it. The bag
ended up getting put up in the cabinet and it was soon forgotten.</p>

<br />
<p>Two years later and with my desire to become more self sufficient I
decided to do something with the corn. Here’s my adventures in corn
<strong>Growing Flour, Field and Dent Corn</strong>
<br />
Corn is a heavy feeder with shallow roots. It is not self-pollinating so
it must have other corn plants near it. Wind is the primary pollinator.
To get a larger crop it is important to plant it in a block rather than
in a straight row. We plant ours in 12′ x 10′ blocks each planted about
a foot apart with a pathway down the center.<br />
<a _mce_href=”” href=””>

<br />
We direct seed our corn rather than plant transplants. I find that this
allows the plant uninterrupted growth because there is no transplant
shock. Once the seedlings are up about 6″ you can plant 2-3 pole bean
seeds around each corn seedling. This is a great symbiotic relationship.
The beans are nitrogen fixers, which helps feed the corn and the corn
makes a great trellis for the beans to climb. We choose to do dry bean
varieties so we don’t have to worry about getting in an picking them
until it’s time to cut the corn stalks down. If you don’t choose to
plant beans with your corn, you can use a natural fertilizer, such as
fish emulsion, once every two weeks. We also like to use rabbit manure
throughout the season to fertilize.</p>
<p>Our biggest pest when growing corn was mealybugs that were being
“farmed” by ants for their “honey dew.” The ants protect them from
predators. We found this to only be a problem with our flour corn
because the corn stays on the stalks for so long. The best way to keep
the ants off were with Tanglefoot smeared around the base of the stalks.
The ants can’t cross it without getting stuck and without the ants, the
natural predators can kill the mealybugs. If you ever get <a _mce_href=”” href=””>Tanglefoot</a> on your skin you can use some olive oil to help remove it and then dish soap to clean up the olive oil.</p>
<p>Late summer or early fall is harvest time. Gently pull the silk and
the top of the husk down to check the kernels. When they are hard, it’s
time to pick.</p>

<strong>Making Masa Flour</strong>
<p>Corn Tortillas require Masa Harina Flour which is specially treated
corn (Nixtamel or Hominy) using a dilute alkaline solution and that has
been ground into a fine flour.</p>
<p>There are two ways to make it. This first time I used <a _mce_href=”” href=””>Pickling lime</a>
(Calcium hydroxide or “cal”) to make the Nixtamel. Making it greatly
increases the nutritional density of the corn by freeing up proteins and
B vitamins.</p>
<strong>What you will need:</strong>
<p>2 lbs dry corn – dent or flour are recommended, but field corn is ok if you can’t find the first two<br />
3 quarts water<br />
1/2 cup Pickling lime*<br />
Large NON-REACTIVE pot (Stainless steel or copper – do NOT use aluminum)<br />
Colander<br />
Grain mill<br />
Large mixing bowl<br />
How to make it:</p>
<p>1. Rinse corn and remove any chaff and debris<br _mce_bogus=”1″>
<a _mce_href=”” href=””>

<br _mce_bogus=”1″>
<p>2. In the large non-reactive pot add water and dissolve the Pickling
Lime. Once dissolved add corn and bring to a rolling boil. Allow to
boil, covered for 15-20 minutes and then remove from heat, let cool and
put in refrigerator for 8-10 hours or overnight. The corn should now be
plumped up and the skins should be falling off. Skim any loose skins off
of the top of the water.<br />
3. Strain Nixtamel in colander and rinse. Roll kernels in hands to
remove excess loose skins. Our corn came out of the alkaline solution
almost black, and once the skins were removed they were a rainbow of
colors.<br />
4. Rinse Nixtamel at least 2 more times. If the corn isn’t rinsed well enough it will be bitter.<br />
The other method of making Nixtamel is by using wood ash. I’ve tried
this once before with mixed results. It’s important that the wood ash is
from hardwood and that it’s thoroughly burned resulting in nearly white
<p>1. Take 2 double handfuls of wood ash from hardwood and add to 3
quarts of water. Boil for 1 hour and then let sit overnight. This
creates lye water* (which you can also use to make soap). Strain the
precipatated ash out of the water.<br />
2. Use this lye water the same as you would the water above with the
pickling lime added. Follow the rest of the instructions above.</p>
<p>*A note about pickling lime and lye water:</p>
<p>Pickling lime and lye water is caustic and can cause irritation
and/or burns if wet hands are exposed to it for too long. If it comes
into contact with your skin rinse immediately. If any spills onto any
surface wipe up immediately and rinse area. I found out the hard way
that it will etch stainless steel (even though it’s nonreactive) and
granite counter tops if not cleaned up right away.</p>
<p>Once the corn is no longer wet you can run it through the mill. We
own an electric mill, but in our move we misplaced it so we went to buy a
hand crank one. We first bought a Shule Mill from a Kitchen Supply
Store. It was the only mill they had. An hour later and after only
producing 1/2 a cup of course flour I was done! It was incredibly
inefficient. That one will be returned this week. We then went and
purchased a <a _mce_href=”” href=””>Victoria Grain Mill</a>. What a difference! In 30 minutes we had run 8 cups of flour through 3 times.<br />
<a _mce_href=”” href=””>

<br />
For every 2 cups of flour add about 1-1/3 cup water and 1 tsp salt. Allow to rest for 20 minutes.<br />
Roll into balls about 1 1/2″ in diameter. Slightly flatten and put in center of tortilla press between two sheets of wax paper.</p>
<p>Cook each tortilla on a hot griddle for about 30 seconds to 1 minute each side. Allow to cool and then freeze until needed.</p>
<p>These tortillas are really tasty. They came out this cool blue/purple color which makes them distinctive.</p>
