Oh yes they do! 20 years ago I had to go for a conference for a week in Southport, dinner and tea were provided, and for tea every day, the caterers provided filled barm cakes. Yummy big soft bread rolls with meat and salad in. Barm is just a dialect word for yeast.
Lancashire hotpot is a traditional dish, a lamb casserole, with sliced potatoes on top so they get crunchy. You could easily find a recipe and make your own. And assuming you've been watching Corrie, it's just the perfect thing to make a big pot of and keep warm so any Rovers customer can have some.
