Wash the lemon hot, dry it and peel it in thin strips with a zest ripper. Halve the lemon and squeeze one half. Peel, quarter, core and dice pears.
Boil up pears, lemon zests, juice, cider and honey. Steam for 3-5 minutes, stirring occasionally, until a chunky compote is formed. Let it cool down.
Cut bread into cubes of about 1 cm. Heat butter in a large pan. Roast the bread cubes in it while turning them golden brown, take them out and let them cool down on kitchen paper.
Whip the cream until semi-stiff, allowing the sugar to trickle in. Remove some lemon zests from the compote. Mix the compote and bread cubes in a shallow dish. Spread the cream loosely on top. Garnish with the lemon zests.
