Butter superfan Felicity Cloake asks whether the movement against ultra-processed foods is linked to a recent rise in popularity of her favourite kitchen staple. Her investigations take her to the rich grasslands of the West Country as she visits Wyke Farms, Quicke's and Ivy House Farm Dairy. She looks at how flavoured butter is taking off and finds out more about the tradition of cheesemakers making whey butter.
Professor Sarah Berry from King's College London gives advice on how much butter we should be eating as part of a healthy diet and food historian Regina Sexton looks at the relationship between butter and Ireland. Felicity also has a turn at making her own butter using an historic dash churn at The Butter Museum in Cork.
Presented by Felicity Cloake Produced in Bristol for BBC Audio by Robin Markwell The programme features a short excerpt of the song "Please Leave My Butter Alone" by Elsie Carlisle.
