Poaching pears: Peel the pears, leaving the stalk intact.
Combine all the ingredients into a small saucepan, the water should be enough to cover the pears, bring to a simmer.
Gently poach the pears for about 15 minutes.
Remove the pears and the spices with a slotted spoon.
Chocolate cake mix: Preheat the oven to 160°C fan / 350°F / Gas 4
Line a 900g (2lb) loaf pan with baking/parchment paper.
Place all of the cake ingredients, except the boiling water, into a large mixing bowl. Using a spoon, or electric whisk, beat the mixture until smooth.
Add the boiling water to the mixture, a little at a time, until smooth. (The cake mixture will now be very liquid.)
The pears should now be cool enough to place into the loaf tin, if they don’t stand easily, you can cut the bottoms straight to help them. Pour the batter in and around the pears.
Baking: Place on the middle shelf in the oven for 45–50 minutes, or until the top is firm to the touch and a skewer inserted into the centre of the cake comes out clean.
Chocolate sauce: Whilst the cake is baking prepare the chocolate sauce by reducing the pear poaching liquid down to about 300ml, then add the cream and cocoa powder to make a rich chocolate pear sauce.
