Yukon Birch Syrup made by Berwyn Larsen and Sylvia Frisch on the banks of the McQuesten River. The catalyst for the experiment was to provide a home-grown vinegar for Suzanne, who is about to embark on her year of eating only the foods she can source in or around Dawson. What to do about salad dressing? (The oil is a whole other topic.) No balsamic for her! Apple cider vinegar is the obvious solution, but Suzanne’s supply of apples from horticulturist John Lenart will be limited, and their primary role to provide fresh fruit for the family. So I turned to locally-available fruit, starting with rhubarb and low bush cranberries. The first attempt failed but the second time appears to have succeeded. Now that the fresh rhubarb is coming, I’ll continue to experiment and see if it makes a difference. Suzanne is experimenting too. Watch for updates, and in the meantime, click here for the recipe. I tested the vinegar with a pH strip and it had a PH of 3. In taste comparisons with commercial apple cider vinegar the apple cider won in terms of both flavour and sharpness. However, I’m delighted with the rhubarb vinegar in salad dressings. It provides the necessary acid. It does its job.
