After watching Top Chef and your favorite Food Network shows, do you ever notice how much you suck at chopping, slicing and dicing? ‘Cause we do. It’s a good thing that Philly Kitchen Share will be hosting “Mirepoix Madness: Basic Knife Skills” on Saturday, February 20, at 1514 South Street, from 4:00 p.m. to 5:30 p.m. For all you folks that are uninformed on the French language, mirepoix is a combination of onions, celery and carrots. Imagine it now: Vegetables flying everywhere! The instructor, Tim McGinnis, will be teaching basic skills — everything from how to properly hold the knife to the fine arts of julienne and chiffonade. Hurry up and buy your tickets now at only $35 a pop (all supplies included) since there are only 10 slots open. Karate-CHOP!
