Slicing open a blood orange has an air of anticipation about it. Will it be intense purple almost throughout, have a few red stripes or actually be mostly orange? Whichever colour you end up with they all have the same fantastic flavour. I love cooking with blood oranges; adding a splash to a cocktail or baking them into something delicious. This recipe for blood orange posset was something I had never tried before and I couldn’t believe how easy it was to make. Just three ingredients are needed for a pudding that tastes so much more than the sum of its parts.
