Nutrition Facts
Per 1g (approx. 1/4 tsp)Chef’s Secret
To prevent clumping, always sprinkle xanthan gum very slowly into a liquid while whisking vigorously, or pre-mix it with a small amount of sugar or oil.
Substitutions
Guar Gum
Good for cold liquids, less effective for baking volume and can impart a slight bean flavor.
Psyllium Husk
Excellent fiber source and binder in gluten-free baking, but can add a distinct texture/color.
Gelatin
Provides gel structure, but not suitable for vegan diets and yields a different texture.
Cornstarch
Thickens when heated, but provides no binding in cold applications and can be cloudy.
Buying Guide
Look for food-grade xanthan gum. A little goes a long way, so buy in small quantities unless you use it frequently.
