Can You Make Roux without Flour?

Save for Later!

It is often assumed that a roux must include flour in its ingredients, but in actuality, you can create a richly flavored and textured roux without flour.

Roux, which is a combination of fat and starch, forms the basis of many sauces, such as bechamel and etouffée.

It's interesting to note that while pure flour was the original form of the starch used to make these amazing sauces, it is possible to substitute other starches like cornstarch or arrowroot with excellent results.

The trick behind making a delicious roux sans flour is all about finding the right balance of fat and starch so that taste and texture are both palatable; underdone roux is usually gritty and greasy, while overdone versions become clumpy and dense.

With practice, anyone can master this technique for producing flavorful sauces without depending on one particular ingredient.

This naturally gluten-free flour is derived from cassava root and is increasingly versatile, as it can be used in so many creative culinary innovations.

As a thickener, it has a distinct texture giving your preparations an unusual body that makes it a very pleasant experience for the palette.

When used as a roux base for sauces or soups, the cornstarch equivalent would be four tablespoons of tapioca flour combined with six tablespoons of water fully incorporated until completely smooth and free of lumps.
