The Blueberry Vinegar will stay fresh for six months and can be put into bottles for a homemade gift. When heating vinegar or acidic foods it's important to use a non-reactive saucepan such as stainless steel, non-stick, or enamel. Aluminum or cast-iron pans react with acid and can cause a metallic taste.
Place blueberries and vinegar in a non-reactive saucepan. Add sugar and orange zest; bring to a boil. Reduce heat and simmer, covered, for 20 minutes.
Strain blueberry mixture though a mesh sieve, pressing out as much liquid as possible. Discard solids. Pour into glass containers.Allow to stand for 1 hour.
(Note this mixture can be refrigerated for up to 6 months.)
Combine oil, parsley, onion, orange zest, salt, pepper and blueberry vinegar in a screw-top jar or bowl. Shake or whisk until thoroughly blended. Let stand at room temperature 1 hour to blend flavors.
Refrigerate.
Shake or whisk before serving.
