I would serve Champagne, personally.
recipe for lemon posset. Serving in a glass would be lovely - perhaps a couple of raspberries and a mint leaf on top for decoration?
Chicken livers you will find in the freezer aisle. This is how I make my pate:
Defrost the livers, and then put in a sieve, and rinse them.
Finely chop a medium onion and a couple of cloves of garlic, and fry gently in a mix of butter and olive oil.
Add the livers to the pan and fry till starting to brown on the outside. (Don't overcook them - it's better if they're just pink inside)
Season with salt, pepper and a little mace or nutmeg and some dried oregano or thyme (which ever flavours you prefer, basically).
Tip this into a blender, and then add a generous sloosh (technical term!) of brandy to the pan, stir and then add this to the blender as well as some double cream (about 4-6 tablespoons). Blend until you have a fine puree, then pour into a serving dish, and chilll till it sets.
If you're not confident about making chips, why not do wedges? Take 2 big potatoes; cut each one in half lengthways, and then half again, and then half again - so you get 8 thin wedges per person. Put them into a shallow oven tray and drizzle generously with olive oil, salt and black pepper. Turn them over to make sure they're coated in oil, then roast in a hot oven for around 30 minutes - check them after 20 minutes as you'll need to turn them over to make sure that they brown on both sides.
