Suet is beef fat, though not just any beef fat. It’s taken from the kidney region of the steer, so in that way it’s analogous to leaf lard from a pig. What’s special about suet is that it’s mild tasting and extremely firm, in fact it’s the hardest of all the fats humans commonly eat. Whoever can tell me what it is that makes suet the firmest of the fats gets a A for this course. Anyone? Anyone? Yes you at the back with the heart condition. That’s right: it’s the highest in saturated fats. Saturation = firmness, that’s rule of fat.
