Found these recipes for you including this one for Suet, from what I can remember you can get all the rest there?
As far as I am aware, suet originates from the thick layer of fat surrounding the kidneys of the sheep or cow. carcass. It is processed and goes into packets in the UK marked with Atora. There is also a vegetarian version which is made primarily from palm oil. You could ask your butcher if he can get you a block of the fat that surrounds kidneys. Place it in a heat proof bowl - cut into chunks - and then allow it to melt in a low oven for a few hours. Any blood/flesh etc will go to the bottom of the dish and you will be left with a block of hard white fat on top which you can grate and use in your recipe. Dust it well with flour before adding it. It is also ok to use in homemade mincemeat for mince pies.

12oz (350g) seedless raisins
8oz (225g) sultanas
