Do you love how vinegars improve and heighten the flavors in food? Do you want to learn more about the wide range of vinegars from around the world, and how you can use them in your cooking? Then you should buy a ticket to the Master Class on culinary uses of vinegar, which FamilyFarmed is presenting on Saturday, March 24 (9 a.m.- 11:30 a.m.) at its Good Food Festival — the second day of its two-day, 14th annual Good Food EXPO. The Master Class and cooking demo features Michael Harlan Turkell, the food photographer, podcaster and author who wrote the wryly named book Acid Trip: Travels in the World of Vinegar. He will be joined by Chef Abe Conlon and Adrienne Lo, co-owners of Chicago’s popular Fat Rice restaurant, which focuses on the Portuguese-influenced cuisine of the Chinese island of Macau.
