Method
    
    
    Preheat your oven to 190°C/375°F/gas 5. Roll out the shortcrust 
pastry to form a rectangular shape just under 1cm thick, using flour to 
dust. Place on a clean, flat baking tray and pinch the pastry around the
 edge with your thumb and forefinger to create a sort of lip.
Remove the core, and slice each pear quarter into 3. Sprinkle with half 
the caster sugar and rest for 1 minute before scattering the pears on 
top of the pastry. Bake for around 18 minutes, or until golden. 
Meanwhile, in a small pan, heat the cream until nearly boiling, remove 
from the heat and rest for a minute before snapping in your chocolate. 
Stir until melted and smooth, then add the remaining sugar and the 
butter. Pour carefully from the middle, covering the pears, and try not 
to let the chocolate go over the edge. Allow to cool briefly before 
popping into the fridge for 20 minutes.
Cut into squares or fingers... and get stuck in!
