Because cornflour is a saturated amylum derive from the endosperm of corn, it acquit otherwise when hydrated liken to flour, which contains both amylum and protein (gluten).

💡 Note: When mixing cornstarch with h2o, deflect habituate hot liquid directly if you require to examine the consistency; a slurry should be do with cold h2o to prevent premature thickening.

Lineament	Cornstarch in Water	Flour in Water
Consistency	Smooth, milky, and thin.	Lumpy, midst, and paste-like.
Dissolve	Dissolves flawlessly without much residue.	Signifier a sticky, viscid batter or simoleons.
Heating Result	Thickens into a open, showy gel.	Thickens into an opaque, floury sauce.
