Arrowroot Powder (Maranta arundinacea)

Pure starch extracted from the rhizome of Maranta arundinacea, Arrowroot, the tropical Caribbean plant. Arrowroot is one of the most useful natural starch thickeners available - gluten-free, neutral-flavored, and capable of producing clearer, glossier sauces than cornstarch. The starch has been used in traditional Caribbean and South American cuisine for centuries.

What is Arrowroot?

Arrowroot is the pure starch extracted from the rhizomes of a tropical Caribbean plant. The starch is exceptionally neutral in flavor and produces a clearer, glossier finished sauce or filling than cornstarch. Traditional Caribbean cuisine has used arrowroot for centuries; the starch was historically widely traded as a colonial commodity. Modern uses center on gluten-free baking and as a clear-finishing thickener for sauces, gravies, fruit pies, and puddings.

Arrowroot vs Cornstarch

Both work as thickeners but have somewhat different properties. Arrowroot: Clear glossy finish (good for fruit pies and clear sauces); thickens at lower temperatures; doesn't hold thickness as long when reheated; gluten-free. Cornstarch: Slightly cloudy finish; thickens at higher temperatures; better for dairy-based sauces; gluten-free. For acidic foods (lemon curd, fruit pies), arrowroot is often preferred because cornstarch can break down in acidic environments.

How to Use Arrowroot

Sauces and gravies: mix 1 tablespoon arrowroot with 2 tablespoons cold water to make a slurry; add to simmering liquid; stir until thickened. Substitute for cornstarch: use approximately 1:1 (arrowroot is similarly potent). Gluten-free baking: replace some flour with arrowroot for lighter texture in cakes and cookies. Fruit pie fillings: a particularly good choice (clear glossy finish, doesn't break down with acidic fruit).

Frequently Asked Questions

What is Arrowroot used for?
Natural starch thickener for sauces, gravies, fruit pies, and gluten-free baking.

How does it compare to cornstarch?
Both thicken; arrowroot produces clearer glossier sauces and works better with acidic foods.

Is it gluten-free?
Yes; naturally gluten-free.

Why is it called "arrowroot"?
One traditional account is that Caribbean Indigenous peoples used the rhizomes to draw out arrow poisons; another is that the leaf shape resembles an arrowhead.

Can I substitute it 1:1 for cornstarch?
Approximately yes; both are similarly potent thickeners.

Why is it good for fruit pies?
The clear glossy finish enhances the visual appeal of fruit pies; the starch doesn't break down in acidic fruit environments.
