Yes, you can reheat sauce thickened with cornstarch, but it requires careful handling to maintain the desired consistency. When reheating, do so over low heat to avoid breaking down the cornstarch structure too quickly, which can lead to a thinner sauce. If the sauce has separated or is too thick, gently whisk in a little bit of water or stock until you reach the desired consistency. Avoid bringing the sauce to a boil, as high temperatures can cause the cornstarch to lose its thickening power.
