Savory blueberry sauces can be prepared without a sweetener,[9] or with a small amount of sweetener,[1][10] and additional ingredients used can include cider vinegar, chicken broth, lemon juice, salt, pepper and corn starch.[1][10] The sauce is used to top various savory dishes such as roasted pork, chicken, lamb and duck.[1][10][11] It is sometimes served on the side, rather than atop dishes.[12]
