Preparation:

Place the ham slices on a tray covered with baking paper or a clean cloth. Add enough so the slice of bread will cover them. Ensure the ham protrudes some two inches at the top and bottom of the bread (not the sides).

Spread the bread with cheese.

Place Valliser quince slices on top.

Carefully cut the bread in half.

Using the cloth or baking paper, start to roll up the bread from the end without ham protruding. This ensures the protruding ham will seal the roll when it has been rolled up fully.

Wrap the roll in polythene so it will not fall apart when cut and place in the fridge to cool.

When it is cold, cut it into six equal-sized pieces. It can be served on shredded lettuce leaves on a tray with a sauce.
