In recent years, a surge of options has emerged for those looking for alternatives to grain based flours and thickeners, particularly those made with wheat or GMO corn. Once expensive and hard to find, dozens of gluten free flours are now easily sourced. Of the numerous choices available, arrowroot is among the most popular due to its versatility and impressive nutritional profile.
The Origins of Arrowroot
It seems hard to believe in this day and age of hybridized and genetically modified foods that arrowroot is actually relatively unchanged from its genetic origins about six thousand years ago similar to einkorn. Over that period of time, this highly prized, nutrient rich starch has nourished traditional peoples from many parts of the world. Few foods can match the historical “roots” of arrowroot flour!
From the Marantaceae family of plants, this starchy tuber has been cultivated and consumed in the Caribbean, South American, and Philippine regions of the world for thousands of years. Above ground, the arrowroot plant produces a dense foliage which is often used as an animal feed (1).
This valuable starch, considered one of Mother Nature’s finest carbohydrates, gained the attention of the West in the early 1900s. This occurred from greater export importance for the island of Saint Vincent, especially as the sugar industry collapsed. Today, Saint Vincent produces only a fraction of the arrowroot it once did, as cheaper alternatives such as cornstarch replaced the more nutritious arrowroot.
With consumers increasingly seeking alternatives to GMO corn compounded by a rapid rise in wheat and corn allergies, however, arrowroot is making a strong comeback of late.
Arrowroot Cultivation and Processing
One of the beauties of arrowroot is found in its cultivation. It is still primarily grown by small farms using traditional, often organic methods even if not so certified. The arrowroot plant is a perfect fit for such farming. It is exceptionally hardy and easy to grow, especially on windswept slopes of Saint Vincent island where it began its journey into the modern world.
The tubers themselves require proper handling before consumption. The extraction process, like the plant’s cultivation, highlight the food’s highly natural bent.
- Arrowroot tubers, which contain about 23% starch, are first thoroughly washed.
- The paper-like scales are removed completely as they have an unpleasant flavor.
- The roots are washed again, drained and finally reduced to a pulp by beating them by hand in mortars or mechanically via a wheel rasp.
- The resulting milky liquid is passed through a coarse cloth or hair sieve which allows the pure arrowroot starch, to settle at the bottom.
- The wet starch is dried in the sun or in a drying house.
- The dried powder is packed in airtight cans or packages to prevent spoilage.
Thus, this traditional food comes straight to us uncontaminated by so many modern agrochemicals such as gut destroying glyphosate.
Besides the benefits of being a nontoxic food, it offers much nutritional value as discussed below.
Arrowroot’s Nutritional Profile
Compared to wheat and corn based thickeners, arrowroot is the clear winner nutritionally. Like many rhizome root tubers, it packs a nutritional punch. It is high across the B-vitamin complex, including folate (not to be confused with synthetic folic acid) and a number of minerals, such as potassium. Arrowroot powder is also slightly superior to tapioca in terms of overall nutrition, but soil and growing conditions probably matter more than the plant species in this regards (2).
While arrowroot is very nutrient rich, it is low in protein. The protein profile is also incomplete with several important amino acids missing.
The starch portion of arrowroot is exceptionally easy to digest and completely gluten free. This makes it ideal as a common food for babies and small children. The sick and elderly find it easy on the digestion as well, which is one reason it was so highly valued by cultures who came to rely on it as a primary food source.
Arrowroot and the GAPS Diet or SCD
Despite its ease of digestion, arrowroot is not allowed on gut healing protocols such as the GAPS Diet, Specific Carbohydrate Diet or Autoimmune Paleo. This is due to its high starch content. Those with an imbalanced gut tend to have trouble fully digesting starch molecules. They are made up of hundreds of monosugars connected in long branchlike strands. Undigested starch molecules serve as the perfect food for pathogenic yeasts, bacteria, fungi and other pathogens to thrive upon compounding the problem.
However, once a person’s gut is healed, arrowroot is a perfect choice as one of the very first starches to reintroduce!
Is Arrowroot a Resistant Starch?
Arrowroot contains low levels of resistant starch, a type of carbohydrate that resists digestion and is turned into energy boosting, inflammation reducing, short-chain fatty acids by beneficial intestinal bacteria. Instead, arrowroot is like most starches in that it is easily absorbed by the small intestine as glucose.
Cooking with Arrowroot
Arrowroot is especially popular because its thickening power is TWICE that of most flours. It is also gluten free and thus widely used in the growing range of gluten free and grain free Paleo foods.
Substituting arrowroot for corn starch or wheat flour
Arrowroot substitutes for corn starch at a 2:3 ratio. One tablespoon (3 teaspoons) of corn starch is replaced by 2 teaspoons arrowroot powder.
For wheat flour, the substitution is a 1:3 ratio. One tablespoon of wheat flour substituted by a single teaspoon of arrowroot powder.
Arrowroot is a strong cooking binder
Arrowroot is superior to cornstarch or grain based flours in most cooking applications. It is a stronger binder, is not weakened by acidic ingredients, and won’t discolor your dishes like other thickeners might.
It also does its magic at a lower temperature, as well as having a more neutral taste. If the food being prepared is going to be frozen, arrowroot is once again the clear winner. Even when compared to tapioca, arrowroot better endures freezing and reheating far better than other options.
Where Not to Use Arrowroot
One place it does not work well is with dairy, where it creates a thick slime.The dairy exception is homemade ice cream, where it prevents the formation of ice crystals. Unfortunately, commercial ice cream manufacturers opt instead for cheap propylene glycol, or edible antifreeze.
Arrowroot flour is not ideal for baking pies or similar creations that are cooked under prolonged high heat. In such situations, tapioca (cassava) can be used as a substitute for wheat flour or cornstarch to thicken.
Arrowroot, like a number of thickeners, requires careful use, as overheating will cause it to breakdown. This results in a loss of thickening power. It is recommended to mix it first with a cooler liquid (such as a set aside portion of a soup or stew that has been allowed to cool), then add this to the larger mixture after it has been removed from heat.
The strong binding nature of arrowroot means it is useful in more than just the kitchen.
Other Practical Uses for Arrowroot Starch
Arrowroot isn’t just a food, but has many other traditional uses too. Ancestral cultures used it to treat poisonous bites and wounds due to it ability to rapidly absorb substances of an undesirable nature. More modern uses include problems like athlete’s foot or other conditions caused by excess moisture.
Arrowroot is ideal for homemade personal care items such as all natural deodorants or bath bombs. It is a great addition to cosmetics because of its nourishing and beneficial qualities, and it also helps improve absorption of lotions and creams. Given the growing concern over the dangers of talc, arrowroot based formulations especially for babies are a safe alternative.
All of these practical uses have served to increase arrowroot’s popularity. So where do we get this nutrient rich, versatile, traditional food?
Sourcing and Storage of Arrowroot Flour
In the past, manufacturers have been known to adulterate arrowroot with cheaper lookalike starches such as potato. This is a similar pattern to other foods. For example, store bought honey is frequently adulterated with high fructose corn syrup. Olive oil, organic or not, is usually “blended” with low quality oils such as canola or other cheap vegetable oils and sold as pure olive oil.
This risk is still very real and will continue to be so given that most consumers remain uneducated about food manufacturer tricks of the trade!
Like with so many foods and products today, make sure to purchase arrowroot from a reputable source. This ensures that you are getting true, genuine, 100% arrowroot powder, not some blend or imitation product. Since arrowroot is generally grown with little to no agrochemicals, it is not necessary to pay a premium for organically certified in most cases.
How to Know Your Arrowroot is Real
Thankfully, it is easy to know if you are getting the real thing. True arrowroot is a fine, light, odorless white powder as pictured above. To test, whisk together 1/4 cup arrowroot powder with 1/4 cup room temperature water. Add to 2 cups boiling water and blend well. Once cooled, the mixture should form an arrowroot jelly that is perfectly smooth in consistency.
Proper Storage of Arrowroot to Maintain Potency
It is extremely important to store arrowroot powder in a cool, dry, dark place in an airtight container. If purchased in a bag, reseal in a second, larger airtight bag (like a ziplock) or enclose in a container with a lid. This serves the dual purpose of keeping the flour fresh and keeping pantry bugs out (who seem to love arrowroot).
If you live in a humid environment, it is best to store in the refrigerator, as old arrowroot will not thicken like it is supposed to after a few months stored in the pantry. If stored unrefrigerated in a dry, dark, cool pantry, arrowroot will retain its thickening potency for about two years.
