Best Cornstarch Substitute in Scones

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 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 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 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 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.
