Semmelknödel?
For something more British, try suet dumplings.
Suet dumplings are always about half fat to flour, so 200g plain flour (+raising agent or use self-raising seeing as you are in the UK) needs 100g shredded suet, mix with water or stock to make dumplings, add chopped chives or parsley with seasoning if you'd like, poach like a Semmelknödel or add to the slowcooker at the end for about 10-12mins.
No suet? Use butter but increase the flour content as suet is drier.
Apple crumble would be a great pudding - I have nursery food-itis today.
