Well, the only plum pudding I’ve had is the canned one from Crosse and Blackwell (which is very hard to find now!) and which I always thought was a reasonable facsimile of ‘traditional’. But looking on the web, I don’t see suet in the ingredients - just partially hydrogenated oils.
I will have to look for more recipes.
Yes, we used to get Crosse & Blackwell at Xmas. I’ll look for one for you. If I see it I’ll gladly mail it to you.
