Water Cress Sandwiches

The hard-boiled eggs can be prepared up to 3 days ahead and stored peeled in an airtight container in the refrigerator. The watercress can be washed and dried up to 1 day ahead, stored wrapped in paper towels inside a sealed container. However, the sandwiches should be assembled no more than 2 hours before serving to prevent sogginess.

These sandwiches are best served immediately after assembly. If necessary, cover tightly with damp paper towels and plastic wrap and refrigerate for up to 2 hours. The watercress will begin to wilt and release moisture after this time, making the sandwiches unappetizing.
