I recommend sealing your leftover dip in an airtight container to store in the fridge. This will keep in the refrigerator for 3-4 days after preparing. This dip can also be frozen! Just prepare as directed above and freeze in a Ziploc bag for up to 6 months. All you need to do before serving is thaw completely in the fridge. This is a great dip to keep in the freezer for last-minute party appetizers. (One note: the dip might lose some of its fluffiness if freezing.)
