Cream the butter with the salt and lemon juice and divide into three equal portions.

Wash, dry and finely slice the chives, and mix into one grated cheese and paprika into the second portion.

Finely dice the ham and eggs and stir into the third portion of butter followed by the cream.

The lobster or crab paste makes the fourth topping. Spread two slices of bread with half of each, then cut the slices in half and trim off the crusts.

Slice the radishes and olives. Cut the gherkins into a fan-shape by slicing almost to the bottom of each and spreading out the sections.

Garnish the chive butter fingers with radish slices, the cheese and paprika butter with chillies, the ham and egg butter with gherkins and the lobster or crab paste with olives.
