Bacon sandwiches with clementine ketchup

Method

1. Bring a large pan of water to the boil and add the clementines. Boil for 1 hour, topping up with water as needed to ensure the fruit stay submerged. Drain and, when cool enough to handle, halve the clementines and remove any pips (although most come without pips these days). Whizz the clementines in a blender until smooth.
2. Pour the clementine purée into a pan with the sugar, vinegar and spices. Simmer for 30-35 minutes until thickened. Pick out the spices and discard, then leave the ketchup to cool and transfer to a sterilised jar. Keep in the fridge until ready to use.
3. To make the sandwich, cook the bacon under the grill until crispy around the edges. Spread mayonnaise on one piece of bread and a little butter on the other. Spread one or both slices with plenty of clementine ketchup (to taste), then add the bacon, sandwich together and eat straight away.
