Arrowroot can effectively replace cornflour in many recipes, offering a clear, glossy finish and a neutral taste.
Understanding the Basics: Arrowroot vs. Cornflour
Arrowroot and cornflour are both popular thickening agents widely used in cooking and baking. While they share similar purposes, their origins, properties, and performance differ significantly. Arrowroot is a starch extracted from the rhizomes of tropical plants like Maranta arundinacea, whereas cornflour (also called cornstarch in some countries) is derived from the endosperm of corn kernels.
Arrowroot boasts a fine, white powdery texture and is prized for its neutral flavor and ability to create a translucent, glossy finish when cooked. Cornflour also has a fine texture but tends to give dishes a slightly opaque or matte appearance. Both thickeners absorb liquid and swell upon heating, but their thickening power and behavior under heat vary.
Why Substitute Arrowroot for Cornflour?
Several reasons drive cooks to seek alternatives to cornflour. Some people avoid corn products due to allergies or dietary preferences. Others want a starch that performs better at lower temperatures or yields a clearer sauce. Arrowroot fits these needs well because it thickens quickly at lower temperatures without breaking down as easily as cornflour does when exposed to acidic ingredients or freezing.
Moreover, arrowroot is often favored for its digestibility and hypoallergenic nature. It’s free from gluten and grain-based components, making it suitable for sensitive diets.
Performance Differences Between Arrowroot and Cornflour
When deciding whether arrowroot can replace cornflour in your recipe, understanding how they behave during cooking is essential.
- Thickening Temperature: Arrowroot thickens at lower temperatures (around 65°C/149°F), while cornflour requires higher heat (around 95°C/203°F).
- Texture: Arrowroot creates a smooth, silky texture with a glossy sheen; cornflour often results in a slightly more opaque or matte finish.
- Freeze-Thaw Stability: Arrowroot does not handle freezing well—it tends to break down and lose its thickening power after thawing. Cornflour fares better in frozen dishes.
- Acid Sensitivity: Acidic ingredients like citrus juice or vinegar can weaken cornflour’s thickening ability over time; arrowroot remains stable in acidic environments.
Because of these differences, arrowroot excels in sauces served fresh or dishes that benefit from clarity, such as fruit glazes or clear soups.
How to Substitute Arrowroot for Cornflour Correctly
If your recipe calls for cornflour but you want to use arrowroot instead, substitution isn’t always one-to-one. Typically:
Use about half the amount of arrowroot compared to cornflour.
For example, if the recipe requires 2 tablespoons of cornflour, start with 1 tablespoon of arrowroot powder. This adjustment accounts for arrowroot’s stronger thickening power.
Mixing and Cooking Tips
- Dissolve first: Always mix arrowroot powder with cold water before adding it to hot liquids. This slurry prevents clumping.
- Avoid prolonged cooking: Once added, cook briefly until the sauce thickens—overcooking can cause arrowroot to lose its thickening ability.
- No direct boiling: Avoid boiling sauces thickened with arrowroot; gentle simmering is ideal.
These steps ensure the best texture and clarity when using arrowroot instead of cornflour.
Nutritional Comparison: Arrowroot vs. Cornflour
Both arrowroot and cornflour are primarily carbohydrates with minimal protein or fat content. However, slight nutritional differences exist:
| Nutrient (per 100g) | Arrowroot Starch | Cornflour (Cornstarch) |
|---|---|---|
| Calories | 357 kcal | 381 kcal |
| Total Carbohydrates | 88 g | 91 g |
| Dietary Fiber | 4 g | <1 g |
| Sugars | <1 g | <1 g |
| Protein | <1 g | <1 g |
| Total Fat | <1 g | <1 g |
Arrowroot provides slightly more dietary fiber than cornflour but otherwise offers similar calorie content and macronutrient profiles. Neither contains significant vitamins or minerals.
Culinary Uses Where Arrowroot Shines Over Cornflour
Certain recipes benefit greatly from swapping out cornflour for arrowroot due to its unique properties:
Sauces and Gravies with Clear Finish
Arrowroot creates transparent sauces that shine on presentation—think delicate fruit glazes or Asian-style stir-fry sauces where clarity matters.
Dairy-Based Desserts
Puddings, custards, or creams that require gentle heating respond well to arrowroot’s smooth texture without curdling milk proteins.
Baking Gluten-Free Goods
Arrowroot blends nicely into gluten-free flour mixes, improving crumb structure without adding grain flavors or heaviness.
Sensitive Digestion Recipes
For those avoiding allergens or digestive irritants found in some grains or corns, arrowroot offers an excellent hypoallergenic alternative.
Limitations of Using Arrowroot Instead of Cornflour?
No substitute is perfect; understanding where arrowroot falls short helps avoid cooking mishaps:
- Poor Freeze-Thaw Stability: Dishes thickened with arrowroot may become watery after freezing and thawing due to starch breakdown.
- Sensitivity to Prolonged Heat: Overcooking can thin out sauces rather than thicken them further.
- Lack of Browning Ability: Unlike some flours used in frying batters (cornstarch sometimes preferred), arrowroot doesn’t promote crispiness as strongly.
- Slightly Higher Cost: Arrowroot tends to be pricier than common cornstarch due to sourcing and processing.
Recognizing these limitations helps determine if substituting makes sense based on your dish requirements.
The Science Behind Thickening: How Does Arrowroot Work?
Arrowroot starch granules swell when heated with liquid starting at relatively low temperatures (~65°C). The granules absorb water rapidly, causing viscosity increase that results in thickened textures.
Unlike some starches that break down under acidic conditions or prolonged heat exposure, arrowroot’s molecular structure resists acid hydrolysis better than corn-based starches. This stability explains why it maintains thickness in lemony sauces or vinegar-based dressings where cornstarch might fail.
The translucent appearance comes from the way swollen granules scatter light less than other starches do—a visual bonus for elegant presentations.
The Practical Answer: Can I Use Arrowroot Instead Of Cornflour?
Yes! You can use arrowroot instead of cornflour effectively in most recipes requiring thickening—especially sauces, soups, gravies, puddings, and baked goods—with some adjustments:
- Use half the quantity of arrowroot compared to cornflour.
- Dissolve it first in cold water before adding it to hot liquids.
Keep cooking time short after adding the slurry and avoid boiling vigorously. This approach ensures you get a glossy finish without lumps or thinning issues.
However, avoid using arrowroot if you plan on freezing the dish afterward or need prolonged cooking times since it loses effectiveness under those conditions.
