Anyone wanting to cook Brazilian food will quickly encounter two ingredients that look identical at first glance: Polvilho Azedo and Polvilho Doce. Both are white powders, both come from the cassava root – and yet, they are not interchangeable in the kitchen. Knowing the difference makes you a better baker.
What is Polvilho?
Polvilho is the Brazilian term for cassava starch – obtained from the root of the cassava plant (Manihot esculenta), which is also known as Mandioca or Aipim in Brazil. Cassava is as fundamental to Brazilian cuisine as wheat is in Europe – and is naturally gluten-free.
The difference: Fermentation
The crucial difference lies in the production process:
- Polvilho Doce (sweet cassava starch) is obtained directly from fresh cassava, washed, and dried – without fermentation. The result is a neutral, mild starch with almost no distinct flavor of its own.
- Polvilho Azedo (sour cassava starch) additionally undergoes a fermentation process lasting several weeks. This produces acids that give the starch its characteristic slightly sour smell and – crucially – special baking properties.
What does Polvilho Azedo do in baking?
The structure of the starch granules changes due to fermentation. Polvilho Azedo expands during baking – without yeast or baking powder. This natural leavening power is the reason why Pão de Queijo gets its typical airy, elastic texture. With Polvilho Doce alone, the rolls would remain flat and dense.
When to use which?
| Dish | Polvilho Azedo | Polvilho Doce |
|---|---|---|
| Pão de Queijo (classic) | ✅ Recommended | ⚠️ Possible, but flatter |
| Biscoito de Polvilho | ✅ Recommended | ❌ Not suitable |
| Beiju (Cassava flatbread) | ⚠️ Possible | ✅ Recommended |
| Mingau (Porridge) | ❌ Not suitable | ✅ Recommended |
| Thickener in soups | ❌ Not suitable | ✅ Recommended |
| Cuscuz Paulista | ❌ Not suitable | ✅ Recommended |
Can you mix them?
Yes – many Brazilian recipes for Pão de Queijo use a mixture of both starches. More Polvilho Azedo = airier and more elastic. More Polvilho Doce = milder in taste and more compact. Experimenting is explicitly encouraged.

Conclusion
Polvilho Azedo and Polvilho Doce are not interchangeable ingredients – they have different properties and different areas of application. For Pão de Queijo and Biscoito de Polvilho, Polvilho Azedo is irreplaceable. For everything else – soups, porridge, flatbreads – reach for the mild Polvilho Doce.
