Sardine Appetizer on Toast

The sardine paste can be prepared up to 1 day ahead and refrigerated in an airtight container. Bring to room temperature for 20 minutes before spreading. Toast the bread circles and assemble the appetizers up to 2 hours before serving; store uncovered in the refrigerator to maintain crispness.

Assembled toasts are best served immediately. If necessary, store assembled appetizers in a single layer in an airtight container in the refrigerator for up to 4 hours. Note that the bread will soften over time. The sardine paste alone will keep refrigerated for up to 3 days.
