  1. Slow Cooker! Why didn’t I think of that. I have been making plum duff for years using my dear mother’s recipe. It’s a bit different but I am using methods from the 1920’s and use a gas burner and a big boiler. Mum used to use the wood copper!! Next one I will try the slow cooker, thanks.

  2. If you soak the dried fruits (raisins, currents, sultanas or golden raisins and homemade candied peel) in the rum in a tight sealed jar, for example a le parfait spring loaded rubber sealed jar, about a month before you are ready to cook the pudding, the fruit is beautifully plump and the moisture in the cake is even better.

  3. My Nannie remembers her mum soaking breadcrumbs in cold tea for a plum duff, has anyone heard of this know this recipe. We’re from Belfast and have been looking for years

  4. Rachel June 20th 2020. I make a fruit teabread which is quite similar and the night before I soak all the fruit in cold tea. You don’t taste the tea but makes the fruit really plump.
