Make Ahead: Our Southern pimento cheese recipe can be made the night before you event. It actually tastes better if you do because the flavors have time to meld. Store it in the fridge covered. Leftovers: If stored in an airtight container, Southern pimento cheese should last one week in the fridge.  Any leftovers after that time should be stirred into pasta, deviled eggs, or scones. Freeze: If you want to use it as a spread or a dip, it's not advisable to freeze it.  The oil from the mayo will separate once it is thawed and the texture will be different--more grainy.   It will become spongy and slightly watery.  It's best to eat it up within one week's time or use it as an ingredient for grits, pimento biscuits, sausage balls, or tomato pie.
