Season with salt and pepper then add your honey and balsamic vinegar and give the pan a gentle shake to mix
Continue to simmer for a few minutes until the liquid starts to thicken and reduce a little
Add your puff pastry on top, prick with a fork and make a hole in the centre
Get it into the oven for 30 minutes at 180oC
