Food safety tips: Always keep the dip refrigerated until serving, and limit the time it sits at room temperature to 2 hours, or 1 hour if it’s above 90°F/32°C, to reduce the risk of bacterial growth in the dairy. If serving at a long cookout, transfer small portions to the table and replenish from a chilled container rather than leaving the entire batch out.
Discard any leftover dip that has been left out beyond safe time limits, and store properly chilled leftovers in an airtight container for up to 3–4 days.
