Pies made in mini muffin tins are always a great hit. You can fill them with any manner of things - finely snipped bacon and beaten eggs and chives, Thai chicken green curry, flaked smoked fish in a cheesy white sauce or, in this case, a beef and mushroom braise. The amount of filling required for each pie is miniscule so make sure it is very tasty and well seasoned. You will only need a generous teaspoon-full to fill each pastry case.
For 10 people, make two dozen pies.
1 Spray or brush your mini muffin trays with oil. Refrigerate the trays.
2 Cut circles with an appropriate sized cookie cutter from sheets of puff pastry - 24 to make your bases and 24 to make your tops. Refrigerate the pastry discs.
3 Finely dice 500g of beef, finely slice 10 button mushrooms, finely dice half a medium onion and crush 2 cloves of garlic.
