Fermented French Fries (& Potato Chips)

fermentation, Vegetable Fermentation

In a makeshift urban root cellar such as we have, the turning of the weather is felt in more places than the breaking of tree buds. While a fermented french fry recipe featured above seems lighthearted and fun, it serves a practical purpose as the tail-end of our stored potatoes also experience an early Spring “bud-breaking” (or spud-breaking?). It works two-fold as what needs eaten needs done with a little more pep, while those potatoes put aside for seed are getting a little pre-sprouting before going in the ground soon enough. The light fermentation adds a more dynamic lacto-pickley flavor to your fries that goes great with traditional condiments, making them worth a try.

Leaving the skin on, cut up the potatoes into your preferred fry shape.

Normally fries get an overnight soak in cold salt water to wash off excess starches. In this case we’ll do the soak as usual, but at room temperature and for a couple more days.

In your fermentation vessel cover the fries with water and add enough salt that the brine has a pleasant lightly salted taste. There’s no wrong answer with salt, except the potatoes will be taking on salt during the ferment, so too much can result in over-salty fries. A light brine enables you to still add salt after frying without overdoing it.

Ferment the fries for a couple days depending on ambient temperature and your preference. We do 4 days in 70 degrees. The potatoes get a nice pungent odor. The final taste is much more restrained than the smell describes so if you’re a lover of the funk, you could keep going. Strain and rinse before you’re ready to fry.

Heat your favorite frying oil- whether that be canola or tallow or other, to 250 degrees and par-fry the potatoes for 7:30 minutes. Work in batches if space in your frying vessel is limited.

Par-fried fries can be held in the fridge to finish for a week or so. When you’re ready for french fries, heat your oil once again but this time heating it to 375 degrees. Cook your fries to your preference, likely somewhere between 2-3 minutes. Strain excess oil and toss with a pinch of salt.

For potato chips follow the same process with these changes/ tips:

Cut whole potatoes on a mandolin- our cabbage mandolin for sauerkraut does the job here. Whether they are thin or thick is up to you.

Ferment the same as with the fries above.

There is no par-frying needed with potato chips. Fry them once in oil at 375 degrees for ~5min or so. The color should be your indicator here. Make sure to move the chips around periodically because they rise to the top and can get some uneven frying. Under-fried parts will be chewy rather than crispy.

Strain and toss in salt, or maybe your favorite spice blend.

Fermenting Homegrown Flax into Linen

farm, fermentation

It’s said that the first automated spinning machine helped kick start the industrial revolution. The practice of spinning fibers itself came from a rudimentary toolset such as a stick and maybe a small weighty rock that was invented independently in different forms all over the world as separate cultures birthed their own thread spinning traditions. And this simple act of spinning, spinning, and spinning fibers, over and over made clothes, bags, and eventually sails for ships to launch out to sea which led to our now global world and using a non-automated spinning wheel would take around 4 and a half years just to spin. Flax is believed to be one of the first cultivated plants and used for its fiber. But in order for the world to hop on the back of flax to fully spin out of control it needed fermentation to carry it from plant to fiber, from flax to linen.

Growing

Flax is a cool weather loving plant so is often sown in the spring in Western Pennsylvania. It has thin strong stalks that reach maybe around 3’ or so. They can be broadcast but doesn’t compete well with weeds like thistle and bindweed. Flax grown for fibers are sown close together to discourage the plant from branching, and the closer they’re grown, the finer the fiber that can be made from them. Conversely if it’s the oil-rich seeds good for eating, paint, and finishing wood that are desired, give em a little more space to multiply with buds. After around 100 days the plant begins to yellow (round mid-July) and the plants are pulled, by hand, with root and all to maximize the fiber length.

Processing

The stalks are laid out to dry for a few weeks (after which threshing can occur to save or obtain the little flax seeds by carefully whacking the stalks). And now things start getting good and rotten, next comes the retting stage.

Linen is a bast fiber meaning that the fibers are collected at the phloem, or inner bark, part of the stem. Incidentally the xylem (outer woody part) and phloem are bundled together by pectin which need broken down to separate out the desired fibers.

The word retting is thought to originate from rot, our dear friend to fermentation. A prolonged saturation of the plant causes the cells around the phloem to burst which in turn invites microbes to come and work on the carbohydrate-based pectin, and this action frees the cellulose fibers from its woody stalk.

Attention must be taken at this stage as under-retting won’t cause proper separation, and over-retting can disintegrate the fibers. Verifying success comes through testing to see if when you break the stalk you can see the fibers separated.

Retting

There are several methods to ret. The first is dew retting where the flax is simply laid in thin layers on the grass to rot with the accumulated morning dew, then dried out during the day (or not), and repeat. Depending on weather this can take a few days to a few weeks and produces a greyer-brown fiber.

Another way is to submerge the dried flax plants in a pond or stream weighed down possibly by rocks. On a large enough scale this method has been trouble for fish and has led to various bans of it overtime. It’s much quicker and produces a more blonde color.

By far the stinkiest is by submerging the fibers into a stagnant pool. This is done in a tub large enough to submerge the stalks. Hose water could work, but like a good starter culture, a cupful of pond water is great to get the microbial activity going. Place a lid on top to keep the water from evaporating in the summer sun, as well as the smell down and it takes about a week. 

Once the stalks are tested and a good break of stalk and fiber is easily seen then they are moved to a dry place out of the weather.

Fibers Emerge

At this point the dried stalks are ready to be broken and shattered which should free the long thin fibers from the woody parts of the plant. It’s quite magical to watch the beautiful blonde fibers released from the confinement of their wooden cell. This is also a step we might save for another time, and instead shove the prepared stalks into the basement to await a winter day when there’s more free time to complete the process.

All the steps to processing hereafter involve cleaning the fibers from the stalks which include breaking (which can be done in a sugarcane press or simple cracking), a whacking to then shed the remaining pieces, and a combing to leave clean, straight, and untangled fibers ready to be spun and then woven.

Our Three Favorite Subsistence Crops

farm, homesteading

Making lists is silly but we did it anyway here because we think there’s some real value in turning people’s attention to the foundations of feeding yourself in our geography where growing tomatoes in your garden is far more popular. Even if you don’t have the space to produce that much food you can still save the seed and pick up the rhythm.

All three of these crops provide a certain degree of simplicity and reliability. They also are generally low maintenance all the way from sowing to harvest, at a home scale require no special equipment to process, while also being straight-forward to store for the winter and having endless uses in the kitchen. Though if I had to pick a favorite crop it would be onions, which brings up another curious point for another day- should your favorite food take priority as your top subsistence food?

Beans

Beans are very easy to grow. Direct sow after the frost up until early June for most varieties. Seed in rows 8″ apart and cultivate once or twice until the bean canopy fills in. Watch out for groundhogs. Leave out until plants dry in the field, but not too long or the pods may mold or shatter. They produce a reliable seed. Bush are easiest to harvest, there is a node at their base you can use snips and clip them at, hauling out the whole plant. For larger plots I’ve taken to coming in with the scythe when the bean pods are about halfway to dry. It’s an efficient way to harvest big patches without shattering too many pods. Climbing beans are more work to harvest.

I’ve learned to finish drying out the beans under a cover in the open like an open barn, porch, or shed, in a pile turning it occasionally to prevent molding. I’ve noticed that the longer you wait to thresh them the easier it is. Most of my beans I’ll wait to thresh until a hot dry day in the spring. And when that time comes they are easy to break with your feet alone, and winnowing is a breeze. At that point they are ready for storage in buckets or other containers that seal out the moths.

Potatoes

Potatoes are wonderful because they can be grown lazily. Put a potato in the ground and get more potatoes. It can be as simple as kicking a little soil over them. Dig trenches if you’re a go-getter and drop them in every foot or so. Look for storage varieties to get through the winter. I use a poor storage type that I think is delicious, maybe the seeds are slowly adapting. When I plant those varieties I just say I’m planting pre-sprouted potatoes. Cultivating can be as easy as hilling them a couple times with a rake, or as many times as you can manage. Voles may gnaw on them but otherwise hopefully they’re left alone. It’s possible to get an abundant harvest in smaller space, around a pound per a potato seed. When the green arial parts die back it’s time for harvest. If the soil is loose enough it could even be done with hands, though a shovel works so long as you don’t slice into them. After harvesting make sure your potatoes are exposed to the least amount of sunlight as possible so they don’t turn green. Let them cure for a week at ambient room temperature, then move them to a cool, dark space.

Corn

I set out to grow wheat as my primary grain initially but ultimately fell in love with field corn which could be either flint or dent. I think the big difference is in harvesting and processing the grains. Corn requires much less labor to get to your plate, and no special equipment. Comparatively to wheat I love the ease of threshing corn. I like to nixtamalize my corn in huge batches and have it on hand as dried hominy. While wet in the nixtamalizing process it can be mashed up for easy masa without a mill. Field corn does require a minimum amount of plants to achieve pollination as its wind pollinated. Four rows at least 4′ long are recommended as a minimum. It also need a lot of nitrogen in the soil to be happy. Depending on your variety sow corn in rows 2- 4′ apart, around 8-12″ apart. Hill and feed with nitrogen as the plants reach your shins. Cultivate a round or two until the canopy fills in, then wait for the plants to die back. The corn is ready when the kernels can’t be dented with a fingernail. Then just pull them off the plants, husk them and give them a good ventilated place to dry. I’ll hang mine, tying them up by the husks, either indoors or outside under a pop tent. After a few weeks of drying they get either bagged up or threshed and stored in a bucket away from mice and moths.
