The big supermarkets don't seem to have any on the shelves or on their websites, we are beginning to wonder whether there's a supply problem - maybe the pumpkin harvest was poor last year or something - but that's a good idea to try Aldi or some of the smaller shops. Saw someone selling a can on Amazon for £35!
This is how I made it, if you follow this link. I didn't have any miso left, so had to leave it out. If you leave it out though I would advise a strong cheese, to make up for the flavour missed from the Miso. You can also add Facon or Bacon if you like www.justonecookbook.com/kabocha-gratin/
I and OH have now had mince pies, couldn't resist, delicious
There is a lot to be said for being part of a group, and the support and friendship that is gained from this.
