Dock seeds are readily available in the wild, and they can be ground into a wild foraged flour with minimal preparation.
While some of the foraged “flour” you can make seems a bit of a stretch, yellow dock is actually a distant relative of buckwheat. The seeds have a similar taste, can be toasted and ground into a wild foraged gluten-free flour.
With two toddlers in the house, this year’s foraging often meant crafting wild foraged treats to peak a little one’s excitement. Foraging with kids can be a challenge, but there’s nothing like bringing back a haul and then spending a bit of quality time in the kitchen making wild foraged cookies as a family.
Often the “flour” you can harvest in the wild isn’t exactly what we’d call flour in the grocery store. Red clover flour, for example, is made from a blossom rather than a grain, so it’ll cook very differently. Similarly, pine bark flour or birch bark flour are made from tree bark, not grain.
If you want real “flour” you need to harvest seed and dock seeds fit the bill nicely.
The plants themselves are cosmopolitan, growing just about everywhere in the world. They’re considered a noxious invasive in many places, and for good reason.
Once dock plants get established they really take over. Prolific seed production, combined with a weedy persistence that just needs the smallest crack to thrive.
Add in a perennial growth habit, and you’ve got a recipe for a persistent weed…that just happens to be a good wild food source in both the country and city.
Dock seeds are abundant much of the year, which is especially convenient when you’re foraging in the winter or late fall when other foods are scarce. The seed stalks persist through the winter months, and since they’re quite tall they’ll remain available above the snow.
Dock plants are perennials, which means they re-sprout from the same spot year after year. In the very late winter and early spring, the new dock plants will sprout and begin to form leaves right under last year’s seed stalks. As that new green growth begins, last year’s seeds are often still clinging to the stalk.
Since dock seeds persist all the way until spring greens sprout, their form allows you to keep foraging during an otherwise bleak early spring mud season. They’ll bring a smile to my face in the spring landscape, long before the first dandelion blossoms.
The individual seeds are inside of a papery husk, and it can be difficult to winnow the seeds from the chaff. I’ve read about multiple methods, none of which seem to be very effective.
The general conclusion seems to be…skip it. Grind the whole seed and chaff into flour, and get a bit of extra fiber in your diet.
The chaff of dock seed doesn’t have much in the way of nutrition, but it won’t hurt you and it’ll help add bulk to your diet. Dock seeds can be used whole to make dock seed crackers, but for most purposes, it’s better to grind it into flour.
To make dock seed flour, start by collecting as much dock seed as you can. The seeds come off the stalk easily once they’re dried, and in an area full of dock seed you should be able to collect several cups in just a few minutes.
Attempting to grind the raw seeds is difficult since while they seem dry in hand, the husks are still quite supple. To really grind easily, the seeds need to be very dry. I’ve found the best method is to toast them on a tray in the oven for about 8-10 minutes.
Be careful to just toast them, not allowing them to burn. Let the dock seeds cool completely before grinding them in a food processor. (or mortar and pestle if you prefer)
The flour can be substituted into your recipes for about up to 1/4 of the flour in the recipe. Keep in mind that it doesn’t have gluten, so the bread won’t rise as high and the texture will be heavier. It’s best to use it in things like crackers or brownies where a heavy texture works well.
How Does Dock Seed Flour Taste?
For an all wild foraged cookie, we mixed dock seed flour with a bit of pine bark flour to make these bark cookies. The kids really enjoyed them, but to me, they mostly tasted like what they were…bark. The flavor of these had more to do with the bark than the dock seeds, and in general, the seeds of yellow dock taste good, a bit like buckwheat.
The main difference? Dock seeds have quite a bit of bitterness that you don’t generally find in supermarket flours.
Samuel Thayer describes many different preparations for dock in his book Nature’s Garden. After going through different ways to cook dock shoots, greens, and roots, he moves on to the seeds noting that “This is the last and perhaps least edible part of this incredibly versatile food plant.
Dock is in the same family as buckwheat, and its seed resembles those of buckwheat in miniature…The seeds themselves are unpleasantly bitter.”
I’ll grant they are bitter, but to my palate, they’re actually the most edible part of the plant. The roots of yellow dock, which many people describe eating, caused me to spend 10 minutes trying to scrub the taste off my tongue.
The leaves are only slightly better. The seeds though aren’t half bad in my book, and they’re readily available. To each his own I guess?
