Do you need a thickener to make your meal tastier? We have a solution. In this article, you’ll find out how to make your soup, pie filling, or sauce creamy and thick.

In many cuisines, the flour represents the great thickener. The reasons are numerous here. Flour is a great asset in French cuisine, and they use a combination of flour and fat, which is very effective for making soups and sauces. If you cook them lightly, you’ll remove the flour taste, and the food tastes better at the end. On the other hand, if you cook the flour and the fat for longer, you’ll make a dark roux that is ideal for stews.

Using flour is also effective when you dredge stew meats in flour because it makes the liquid thicker as you cook the meat. As a result, your meal will be much tastier. You can also use flour in stews, gravies, and dairy-based sauces, as the flour thickens the structure of the meal and it does not lose its thickening power even if you simmer the meal for longer.

You must be careful when you use cornstarch for your meal. It is a completely pure starch that combines good with the liquid, but you must know the right proportions. Add equal parts cold liquid and cornstarch when you want to make a slurry. After that, you are good to cook the meal for a short time, because longer cooking will break down the cornstarch and your meal will be full of unwanted particles. Therefore, avoid long cooking and do not use acid ingredients, like lemon, tomatoes, or vinegar, since the sauce can lose the consistency.

Unlike cornstarch, you can cook with arrowroot even if you add acidic ingredients to your meal, and you can also freeze the food at the end. Similar to the cornstarch, you must make a slurry before adding the arrowroot, but the cooking process could be much shorter. When all these characteristics combine, the arrowroot creates a very pleasant texture and silky mouthfeel.

Flax seeds
