For the wild garlic eggs, rinse the wild garlic leaves with cold water, shake dry and chop coarsely. Place in a bowl with the olive oil and puree with a hand blender.
Peel the eggs, cut them in half lengthwise and put the yolks in a bowl. Mash to a pulp with a fork. Cream butter with the mustard until fluffy. Mix all ingredients together until well blended. Place in a piping bag fitted with a fine nozzle and pipe the cream onto the egg halves. Serve the wild garlic eggs with fresh wholemeal bread.
