I took a vinegar making class from Pascal Baudar, author and traditional food preservationist, last week and just in time to make my own blackberry vinegar. Pascal took us through all of the calculations, and steps to turn fruit scraps into vinegar. I furiously took notes while my new baby kittens clawed and hissed at my feet. So of course I was glad that the course was recorded so I could go back and decipher the chicken scratch I had written in a hustle.
