What's this then?

Fruit for plum pudding, and the Dupont Calvados that it has been soaking in for two weeks. The white chunks are suet; acquired with some difficulty, but the local butcher did come through, and on opening my white paper-wrapped parcel of beef fat I was happy to discover that there was a sliver of kidney still attached.
It's been made (steamed for 9 hours), so stay tuned for pictures when I unleash it tomorrow night as a treat for Chefs Mike and Brian at Slows.....
