Wrap each caramel in a square of parchment paper and place them side-by-side on sheets of parchment paper and layer them in an airtight container.
For an extra chocolate version with fleur de sel, melt and temper milk or dark chocolate. Dip the caramel squares in the tempered chocolate, one at a time, using a fork. Let set on a sheet of parchment paper and drop a few grains of fleur de sel just before the chocolate sets up.
