I'm thinking of trying this recipe but have only ever used a traditional recipe with a combination of the standard dried fruit, can someone tell me where I can purchase the dried cherrie, blueberries and plums (are these prunes?), also I would like to try steaming in a pudding basin or bowl which both fit easily in the basket, would this be ok? I've always used calico because that's the way I was taught but I really hate trying to get it even and tying the strings tight enough.
