I have bought rendered leaf lard from the Spotted Trotter, which was the source of my complaint about cost!! I’ve asked around for the raw stuff, but no shop I know of can get it. Specialty restaurants and the Spotted Trotter are apparently buying it all up! Another problem is that almost no one is raising lard hogs anymore, so no one has the yield they used to have. Such a shame.
Beef kidney suet is also tricky to find, but it is possible. I ended up buying an awful lot, which has lasted a few years. So far, no freezer taste, but my luck is going to run out soon. There’s nothing in the world like frying potatoes in rendered suet, but I keep most of mine whole for steamed puddings. I only need 4 oz at a time, though, which is why my 10 lb supply is still with me!!
