I've don mini yoekshire puddings with cocktail sausages.
A pizza, home made or bought but cut with a pastry cutter so they are tiny.
One of my go tos is dried apricot, soaked over night so they plump up, put a piece of brie in and wrap with streaky bacon, they only need 10-12 mins in the oven.
Filo parcels - cream cheese and salmon bits or mango chutney with brie or cream cheese and mushroom.
Mango chutney is really easy to make and you can make it now and let it age.
For a 1lb jar or jam jar you need 2 mangoes, sugar and pickling vinegar, spices and a handfull of sultanas.
Peel one mango and chop them both and put in a pan with a 50/50 mix of sugar and vinegar, throw in the spices and sultanas and simmer for about an hour.
When you can draw a wooden spoon accross it and it leaves you seeing the bottom of the pan it is done. Put in a sterilised jar and leave for 2 weeks.
After 2 weeks it is ready but you can leave it longer.
I also do a thing which is a jar of nibbles, basically get an empty jar, fill it with slices of mushroom, sliced olives, finely sliced peppers, capers, and a peeled clove of garlic. Fill the jar with oil and tap to get rid of any air bubbles.
Again leave for a couple of weeks then try it with crusty bread.
