Variations
Add cooked bacon bits for a smoky flavor.
Stir in caramelized shallots for a sweeter, more delicate taste.
Use Gruyère or Swiss cheese for a richer profile.
Add a pinch of cayenne pepper or chili flakes for heat.
Mix in fresh herbs like thyme or chives for added freshness.
Storage/Reheating
Store leftover dip in an airtight container in the refrigerator for up to 3 days.

You can also microwave in short intervals, stirring between each, though the texture is best when reheated slowly.
