This sounds like my normal Christmas offerings, I just do what my mum did when I was a child (of the 70’s) and add whatever takes my fancy.
Advocaat, lemonade, lime cordial and cocktail cherries for snowballs.
Vol au vents with leftover turkey, make a white sauce and add a chicken oxo cube and stir well on the heat until it thickens. You can buy the cases frozen or make your own from puff pastry.
Dates stuffed with marzipan & dipped in chocolate, medjool are best.
Cinzano, Martini Bianco and Babycham, though it tastes nothing like it used too :(
Sausage rolls, sausages on sticks, peanuts, piccalilli, finger food in general the beiger the better! Definitely a prawn ring.
Jelly fruits, chocolate liqueurs and sugared almonds and mice.
Nuts you need to shell, Brazil, Walnuts and hazelnuts. Buy at least 4 nutcrackers if you do this and expect lots of swearing.
