About potato starch
Potato starch is a fine, white powder extracted from crushed potatoes, prized for its neutral flavour and exceptional thickening power. It creates a clear, glossy gel when cooked, making it ideal for sauces, gravies, and Asian-style dishes. Unlike wheat flour, it is naturally gluten-free and produces a silkier texture without cloudiness.
Best substitute
Cornflour (cornstarch) is the closest match to potato starch in terms of thickening power and producing a clear, glossy finish. It performs almost identically in sauces, gravies, and stir-fries, though it can turn slightly cloudy at very high temperatures.
Alternative
Arrowroot produces a similarly clear, glossy gel and is an excellent gluten-free substitute. It works well in acidic sauces and freezes better than cornflour, though it can become slimy if overcooked or combined with dairy.

Tapioca starch (tapioca flour) thickens similarly and produces a clear, slightly elastic gel. It is particularly well suited to Asian recipes and pie fillings, and holds up better than cornflour when frozen.
Alternative
Plain (all-purpose) flour can thicken sauces and gravies but requires roughly double the quantity and produces an opaque, less silky result. It must be cooked out for at least a minute to eliminate any raw flour taste and is not suitable for gluten-free diets.
Alternative
Rice flour is a mild-flavoured, gluten-free alternative that thickens effectively without significantly altering flavour. It produces a slightly less glossy result than potato starch and works best when whisked into a slurry before adding to hot liquids.
