My absolute favourite Christmas prep activity is the annual pilgrimage to The Cotswold Cheese company.
Dm, dds and I go and have a good test before settling on our cheeses:
A strong, salty cheddar. Black bomber is great. Mull of Kintyre is also lovely and less "set your teeth on edge" for guests who need a milder one. (Or just disinvite them. It's a valid reason.)
Another vote for standard baron bigod. Just buy the whole wheel and thank us later
Reserved for Christmas only is the Wensleydale with apricots.
Camembert. But you must serve it gooey and with a sweet red onion chutney. Nothing else will be accepted in our house.
Blue - not many fans of blue here so we usually have a cambozola to appease DH.
Carboncino di Capra - this is a mix of cow sheep and goat milk. Good tangy flavour and a bit of a treat for Christmas!
I think you asked for 3 cheeses. But clearly I have no self control and must have been a mouse in a former life.
Also don't forget excellent crackers and chutneys. Don't spoil your delicious cheesy excellence with crap biscuits!
