Xanthan gum and guar gum often appear in the same part of the baking aisle, and both can help with binding and thickening. That does not make them identical. The right choice depends on the recipe you are following, the texture you want and the directions on the current product pack.
This practical comparison explains what the two pantry ingredients have in common, where their roles differ and how to test them without wasting a whole batch. It is general cooking guidance rather than a replacement for a tested recipe or the directions on a product label.

What these ingredients actually do
In many recipes, flour proteins or other structural ingredients help a mixture hold together. A gum can be included in a tested formula to support binding, thickness or stability. That may matter in a loaf, biscuit dough, batter, sauce or dressing, but the job changes with the recipe.
The safest rule is simple: treat xanthan gum and guar gum as recipe ingredients, not universal corrections. If a published recipe specifies one, start with that one. Adding more than directed can change the texture quickly, while adding a gum to a recipe that was not designed for it may not fix the underlying balance of flour, liquid, fat and leavening.
How to choose between xanthan gum and guar gum
1. Start with the recipe, not the pantry
Look for a recipe that states the exact gum, quantity and mixing method. “Add a little” is not precise enough for an ingredient normally used in small amounts. If the recipe calls for xanthan gum, PBCo Xanthan Gum Premium 80g lists 100% xanthan gum. If it calls for guar gum, PBCO Guar Gum Premium 80g lists 100% guar gum.
2. Check what other structural ingredients are present
A flour blend may already contain a gum. Read the full ingredient panel before adding more. Also check whether the recipe depends on eggs, starches, seeds or another binder, because a substitution can alter more than one part of the formula.
3. Keep leavening separate from binding
Baking powder has a different job. It is included to help suitable baked recipes rise; it is not a substitute for xanthan gum or guar gum. The current ingredient list for PBCo Baking Powder Aluminium Free 120g is gluconolactone, bicarb soda, rice flour and calcium phosphate. Use it only where the recipe calls for baking powder and follow the pack directions.
A low-risk way to test a substitution
- Make a small batch. Halving a recipe reduces waste while you learn how the change behaves.
- Weigh accurately. Small ingredients are difficult to judge by eye. Use the unit and quantity specified by the recipe.
- Change one variable. Keep the flour blend, liquid, mixing time and bake temperature the same.
- Record the result. Note whether the mixture was easy to handle and how the baked texture changed after cooling.
- Adjust only on the next batch. Multiple mid-mix additions make it hard to understand what worked.
Common problems and useful checks
The batter became unusually thick
Stop adding the gum and compare your measurement with the recipe. Check whether the flour blend already listed a gum. Avoid guessing at extra liquid unless the recipe offers a tested adjustment.
The bread or cake still crumbles
A gum is only one part of the formula. Check the flour blend, liquid ratio, eggs or replacement ingredient, mixing method, pan size, bake time and cooling instructions before assuming more gum is the answer.
The gum formed small lumps
Follow the recipe’s mixing sequence. Some recipes distribute a small dry ingredient through the other dry ingredients before liquid is added. Do not improvise if the product or recipe gives a different method.
Storage and pantry organisation
Keep each ingredient in its original labelled pack or a clearly labelled airtight container, and follow the current manufacturer storage directions. Because the powders can look similar, labelling helps prevent an accidental swap. Store measuring tools clean and dry, and avoid returning a damp spoon to the pack.

Frequently asked questions
Are xanthan gum and guar gum the same?
No. They are different ingredients, even though both products featured here are described as thickeners and binders. Use the one specified by your recipe unless the recipe author provides a tested substitution.
Can I replace baking powder with xanthan gum?
No. Baking powder is a leavening ingredient, while xanthan gum is sold here as a thickening and binding ingredient. They are not interchangeable.
How much should I use?
Use the amount in a tested recipe and follow the current product label. The appropriate quantity varies with the food and total batch size, so a single universal measure would be misleading.
Do I need both in my pantry?
Not necessarily. Buy for the recipes you actually make. One clearly labelled product that matches your regular recipes is more useful than several rarely used ingredients.
