In the second episode, Grace is given exclusive access to Greggs' secret innovation centre at their HQ in Newcastle, getting a sneak preview of their new product ranges and let loose on some muffin making which has the potential to go horribly wrong when Grace takes charge of piping the jam.

But what of the future of Greggs? Grace meets DJ and star of Celebrity Gogglebox Woody Cook as they test out the Primark/Greggs collaboration, the Tasty Café. What do millennials think of a brand that even manages to sell out a range of Greggs clothes and has somehow become cool?

One item that really transformed the bakery giant's fortunes was the vegan sausage roll – a surprising hit that's made them a fortune. Grace enjoys a novel trip through her first Greggs drive thru, and the company's CEO introduces her to hot yum yums – a revelation and the icing on the cake.
