what is the difference between tallow and lard
Suet is beef or lamb fat, ie lard, found around the animals' loins and kidneys. Kidney suet is more common - pure white with little flavour. Tallow is a rendered or melted-down suet. Many cultures eat horse: just like others eat dog, cat, cavy [guinea pig], rat, possum, moose, buffalo, elephant, etc...
But actually, there are a lot of differences between the two than just the name. For starters, lard is made out of animal fat, usually the fat of the pig. There are also a number of different lards that are made out of the fat from other animals such as duck fat and goose fat. On the other hand, shortening is made from a variety of different oils.
