Using Xanthan Gum Instead of Cornstarch
Ratio
¼ tsp per 1 tbsp cornstarch, whisked in gradually
Moderate — noticeable differences, use with care
Recipe Adjustment Notes
Thickens without heat and holds up to acid and freezing. Very easy to overdo — too much turns sauces slimy.
The Science Behind This Swap
A hydrocolloid that thickens by binding water directly rather than by gelatinising starch, so it needs no cooking.
Measurement Variance Note
For 1 cup references, this ingredient can vary by about 6% across brands and measuring methods (120g-136g per cup). For the most reliable substitution result, measure by weight and test a half batch first.
