Pig trotters, also known as pig's feet, are a popular ingredient in various cuisines around the world. They are the foot part of a pig, excluding the hock, which is severed at the joint. They are typically covered in a tough, thick skin and have a good amount of collagen, marrow, fat, and little meat.

Pig trotters are often used in slow-cooked dishes where they have ample time to tenderize and let their collagen infuse into the broth to make it rich and flavorful. When cooked properly, the skin, fat, and meat fall away from the bones and become beautifully soft and delicious. They can be braised, stewed, or even pickled and require thorough cleaning before use.

Pig trotters are not a mainstream choice of meat, possibly due to their high fat and collagen content. But, they are actually quite nutritious. Besides being a good source of protein, they also offer a variety of nutrients, including Vitamin B, Iron, and other minerals.

Whether you're wanting to produce a flavorsome stock base for your soups or stews, or you just want to dig into a delicacy that's been savored in many cultures for years, pig's trotters could be just the ingredient you're looking for.

Pig Trotters can usually be found in the meat section of a grocery store. They may also be available at a butcher shop within the store if they have one. However, not all grocery stores carry them so you might need to check specialty stores, international markets, or ask your local butcher. Extra tip, some online grocery platforms also sell them.
