Arrowroot starch: thickening sauces and creams

Arrowroot, also known as maranta starch, can thicken water-based preparations in the kitchen. Treat it as a starch ingredient: it is not automatically low in carbohydrates or suitable for a ketogenic diet.

How to incorporate it

To reduce lumps, mix arrowroot with a small amount of cold liquid, then stir it into the preparation. Traditional starch develops texture when heated; it should not be expected to thicken immediately without heat like a product formulated for that purpose.

The dose and treatment depend on the recipe. Start with a small trial and observe the sauce after cooking and cooling. A highly acidic preparation or one exposed to prolonged heat may behave differently from a simple water-based liquid.

Where it can help

Consider arrowroot for sauces, creams and fillings when the method includes heating. Adding it to a baking dough does not automatically give it the structural function of gluten or gums.

Substitution with other starches also needs testing: a fixed ratio for every flour ignores differences in absorption and the desired result.

Choose according to the method

To adjust a sauce without cooking, compare arrowroot with Ultratex or xanthan gum for cold thickening. For gluten-free cooking, check the suitability of every ingredient and avoid contamination throughout the preparation.
