I enjoy a dirty rice recipe that has you sauté onions, celery and green peppers in sausage grease and then add a tablespoon of flour. What does the flour do?



Best Answer

Fat + flour form a roux, the base for creamy/starchy soups and sauces.

You don't give details, but Cajun recipes often let the flour/fat mixture get rather dark, which will contribute more flavour while significantly reducing the binding properties, so I suppose this is the case here, too.

Rule of thumb: Lighter for thickening, darker for flavour.

The moment you add the liquid in your recipe, a sauce forms, which will then coat the rice and let the veggies and spices "stick" to it.

How do you keep onions crispy when cooking?

The main reason sweet onions taste so much sweeter than other onions is that they are low in sulfur compounds, especially pyruvic acid, which gives regular, or storage, onions their pungency.

Why do grilled onions taste sweet?

Cool completely before storing. \u25ca How to store in the freezer: If the caramelized onions are somewhat soggy (limp and not crispy), wrap in small plastic-wrap packets of 2 Tbsp each, stored in resealable sandwich bags -or- if crispy enough (as this recipe is meant to be), stored in glass jars with a tight lid.
