This episode of thine TickyOff features food science legend Harold McGee talking his new book all about the wonderful world of smell. Harold also talks Heston, his McDonalds order of choice, the time he whipped some eggs in a prize given to his wife, the most disgusting bit of research he’s ever done and how he cooks at home.

Before Harold shows up on the line from San Francisco, James reveals all about his new role in the kitchen at The 10 Cases and how a ramekin of mustard nearly caused a full blown temper tantrum. Sam meanwhile has been to Brat, talks his favourite word and gives a shout out to the new book by friend to the podcast Tim Hayward.

There’s also time to diss tomato risotto, congratulate Thom Yorke from Radiohead on his wedding and talk ugly wine bottles.
