How Do You Thicken Corned Beef Juice?
To thicken corned beef juice, you can create a slurry by mixing equal parts cornstarch and cold water, then slowly stirring it into the boiling corned beef juice. Alternatively, you can make a roux by melting equal parts butter and flour in a saucepan over medium heat, then gradually adding the corned beef juice while whisking constantly, until the desired thickness is reached. Note that with both methods, it is important to continuously stir while heating to prevent the mixture from clumping or burning.
