Green Mayonnaise (Irish)

Serve with cold poached salmon, Dublin Bay prawns, and other fish and shellfish.

1 cup Hellmann's mayonnaise (240 mL)
1 bunch watercress, trimmed and finely chopped
6-8 fresh chives, snipped into small pieces

Put 2 Tbsp. of the mayonnaise into the bowl of a food processor and add the watercress and chives. Pulse several times to obtain a rough purée.

Put the remaining mayonnaise in a small bowl, then mix the watercress mixture in well.

Makes about 2 cups (475 mL).
