Mark Studley is a self-taught chef whose over-the-top burgers and street food have won many fans (and awards). He stumbled into the business almost by chance “I got fed up with paying money for rubbish food. I thought I could do it better”, and opened the Cow N Bun burger bar in Somerset. He now works as a private chef, and Dirty is his first cookbook. The book won private chef platform YHangry’s cookbook of the year award in 2022. ckbk co-founder Matt Cockerill spoke to the chef to understand the dirty ethos.
