Crackling Fat is made from pure pork fat. It doesn’t smoke at high temperatures, making it perfect for frying or roasting. Use it instead of butter to give fried potatoes or any other vegetable a heartier flavor. Or spread it on rye bread and sprinkle with salt and pepper for a quick snack. Storage Information Will keep up to 3 weeks in the refrigerator, or can be frozen for up to 2 months.
