Bonnie Garmus, author of the bestselling novel Lessons in Chemistry, shares the story of her life through five dishes. Ruth Alexander meets Bonnie in her London home, to talk about the food influences in her debut novel about a female chemist turned TV cookery show host in the 1950s and 60s. She’ll hear about Bonnie’s childhood growing up in California, her own personal experiences of sexism in the workplace, the adoption of her Chinese daughters and her relationship with her husband David. Bonnie will bake a dish that features in her novel, ‘desperation brownies’. If you would like to get in touch with the show, please email: thefoodchain@bbc.co.uk Presented by Ruth Alexander.
