Thicken the sauce with cornstarch
If you find during cooking or at the end that your sauce is too thin, you can use cornstarch to thicken it. You will need 1 tablespoon of cornstarch and some water.
- Mix the starch with the lukewarm water using a whisk until it dissolves without lumps.
- Pour the liquid into the already heated sauce while stirring.
- Let everything boil for a few more minutes until the desired consistency is reached.
Thicken the sauce with a roux
A roux is a popular way to thicken sauces and give them a creamy consistency. All you need is butter and flour in a 1:2 ratio. To bind 250ml of sauce, you should make about 30 grams of roux. For this, you need 10 grams of butter and 20 grams of flour.
- Heat the butter (or vegetable margarine) in a saucepan until it is liquid.
- Gradually add about twice as much flour as butter and stir this vigorously into the butter with a whisk until a dough-like mass is formed.
- When the flour and butter have combined into little golden lumps, gradually add the sauce liquid while stirring and let it simmer for a few minutes.
Thicken the sauce without ingredients
If you don’t have any flour or cornstarch at home, you can thicken your sauce without any additional ingredients.
- Let the sauce simmer in the pot with the lid on over low heat for about 20 minutes, stirring occasionally.
- Due to the long cooking time, the water in the sauce evaporates and the consistency becomes creamier.
- However, this method also reduces the amount of sauce you use. So only let the sauce simmer for as long as you have enough liquid to start with.
