White Roux and the low FODMAP diet
A classic white roux is a simple cooking foundation made by heating equal parts butter and wheat flour until lightly combined. The high fat content in butter effectively coats the wheat starches, which limits their rapid fermentation in the small intestine. Although wheat flour contains fructans, the small quantity used to thicken a standard portion of food keeps the total load minimal. This technique is widely used in French and Southern American cuisine to create smooth gravies and bases. You can confidently incorporate it into recipes when following strict dietary guidelines.

What can change the result?
If you require a completely wheat-free version, substitute the standard flour with an equal amount of certified gluten-free oat or rice flour. The cooking time directly affects the flavor, so keep stirring constantly to prevent scorching and preserve the mild taste. Remember that roux is typically diluted into larger volumes of liquid, which further reduces the concentration of any fermentable carbohydrates. Use clarified butter if you are particularly sensitive to even trace amounts of dairy lactose.
