Deeper Dive: Using Cornstarch Substitutes in Scones
What Actually Happens in Practice?
Using arrowroot powder instead of cornstarch in scones typically results in a lighter, more tender crumb with a slightly glossier surface due to arrowroot's superior thickening at lower temperatures. It also imparts a neutral flavor, preserving the scone's intended taste profile. Arrowroot gels quickly when mixed with cold liquids, so it's best to incorporate it carefully to avoid clumping.
Common Mistakes to Avoid
A frequent error is substituting arrowroot powder in a 1:1 ratio without adjusting for its stronger thickening power, which can lead to overly dense scones. Another mistake is exposing arrowroot to prolonged high heat or acidic ingredients, causing it to break down and lose thickening ability, resulting in a runnier dough. Additionally, failing to mix arrowroot thoroughly with dry ingredients can cause uneven texture and spotting.
How Results Can Vary
Results with arrowroot powder can vary depending on oven type; convection ovens may brown scones faster, potentially degrading arrowroot’s thickening before full bake. At high altitudes, the reduced atmospheric pressure can cause scones to rise and set more quickly, requiring slight adjustments in arrowroot quantity to maintain tenderness. Variations in arrowroot brand purity and freshness also impact gel strength, influencing final crumb structure.
Edge Cases & Exceptions
In gluten-free or vegan scone recipes using alternative flours, arrowroot powder may interact differently, sometimes necessitating a blend with other starches like tapioca to achieve ideal texture. For large batch commercial baking, arrowroot’s cost and sensitivity to heat might make potato flour a more practical substitute. Additionally, recipes incorporating acidic fruits or citrus may degrade arrowroot’s thickening, making potato or rice flour preferable in those cases.
Detailed Guide: Each Cornstarch Substitute in Scones
Arrowroot Powder
Arrowroot powder is a fine starch extracted from tropical plants and acts as a neutral thickener similar to cornstarch. It gelatinizes at a lower temperature, which helps in moisture retention and contributes to a soft crumb in baked goods like scones.
For best results, mix arrowroot powder with the dry ingredients thoroughly to ensure even distribution. Avoid overheating the batter as arrowroot can break down under prolonged high heat, potentially reducing its thickening power.
Compared to cornstarch, arrowroot produces a slightly glossier texture but remains neutral in taste and does not alter the scone’s crumb structure, making it an excellent one-to-one substitute.
Rice Flour
Rice flour is a finely milled flour from rice grains and can mimic some thickening properties of cornstarch in baked goods. It absorbs moisture well and can help maintain structure without adding gluten.
When using rice flour, ensure it is sifted well to avoid clumping and mix thoroughly with other dry ingredients. It may require slightly more liquid in the recipe to compensate for its absorbency.
Rice flour can make scones a bit denser and less tender compared to cornstarch but still yields an acceptable crumb with a slightly different mouthfeel.
Potato Flour
Potato flour is made from whole potatoes and contains more fiber and starch than potato starch, providing moisture retention and thickening. It can help keep scones moist but tends to create a heavier crumb.
Use potato flour sparingly and mix it evenly with other flours to avoid clumping. Monitor baking time as scones may require slight adjustments due to moisture content.
Compared to cornstarch, potato flour results in a moister but less crumbly scone, which may be less desirable if a light texture is preferred.
Tapioca Starch
Tapioca starch is derived from cassava root and is a strong thickener that gelatinizes quickly. While it can replace cornstarch, its tendency to create a sticky, chewy texture can be problematic in scones where a tender crumb is desired.
To minimize chewiness, combine tapioca starch with other flours and avoid overmixing the dough. Baking at the correct temperature is critical to prevent excessive browning.
Scones made with tapioca starch may have a slightly gummy texture and less flakiness compared to those made with cornstarch.
Wheat Starch
Wheat starch is the starch extracted from wheat flour and acts similarly to cornstarch in thickening. However, it contains gluten, which can develop into a stronger network in scone dough, potentially making the texture chewier and less tender.
Use wheat starch only if gluten content is not a concern. Mix thoroughly with other dry ingredients to ensure even distribution.
Compared to cornstarch, wheat starch can produce a denser, less crumbly scone with a slightly different mouthfeel due to gluten presence.

What NOT to Use as a Cornstarch Substitute in Scones
Using all-purpose flour as a substitute in scones can result in a denser, heavier texture because it contains gluten and does not have the same thickening power as cornstarch. This can interfere with the light, crumbly nature typical of scones.
Potato starch tends to create a gummy or overly moist texture when used in scones, which can negatively affect the crumb structure and make the scones less flaky and tender.
