This fast and easy recipe is credited to Cynthia Charbeneau of Traverse City, MI. I made the recipe from the www.fustinis.com website. Fustini's is a store in Traverse City that specializes in all sorts of different olive oils and balsamic vinegars. The balsamics and olive oils also come in infused varieties (I just bought a pomegranate infused balsamic for salads). I love shopping in this store when I am up north. On the website, very few ingredient proportions are listed for this recipe, so I listed the proportions I tried tonight. I would never have thought I would enjoy strawberries with fish, but I really thought this dish was a winner. DH said he "liked it." I used Fustini's 18-year aged balsamic vinegar. I omitted the sugar and water. DH always cooks the tuna steaks by first putting them in the oven on 200F for a short time before pan searing them. This way, they are still rare (but not cold) on the inside. I put the strawberry/balsamic combination in a saucepan on the stovetop between medium low and low, just enough to warm them up. I served with one of our favorite salads, Recipe #191024 191024, using Fustini's 12-year-old white balsamic vinegar.
