WHAT YOU NEED

Heat the oil in a large heavy bottom pot over medium heat. Add mince and cook off stirring to break up. Ensure it is cooked off and completely separated (about 10 mins).

Remove from saucepan into a fine sieve saving the fat that drains. Add the fat that drains off back to saucepan and brown the cheek pieces in one layer at a time in this fat.

Remove cheeks, drain fat again. Using half the wine, deglaze pan.

Place cheeks into a bowl  pour wine over cheeks and set aside. Add fat back to pan, add onions and garlic, thyme and rosemary and sweat for about 10mins, add celery and sweat for 10 mins more.

Add the other half of the wine, half of the stock and the vinegar and let bubble for about five minutes.

Add tomatoes, the rest of the stock, cheek and red wine mix, mince, salt and pepper. Simmer over low heat for about 1.5hrs with lid on until meat is 3/4 cooked.

Add mushrooms and stir through, cook for about 10mins more. Mix potato starch with a 60ml cold water and stir through. Bring back to boil.

Mix the flour, butter No1 and salt on slow speed until it resembles sand (about 5 mins if using a mixer).

Add water and vinegar and bring together on slow speed (about 2 mins) until just mixed and leaving no lumps. Press into a rectangle and refrigerate overnight.

With a rolling pin beat the refrigerated butter for folding into a rectangle about half the size of the puff pastry rectangle.

This should leave the butter cold yet pliable. Do two single folds and rest overnight. Do two more single folds. ie. 4 folds in total, rest overnight again.

The next day roll out to about 4mm thick and cut into circles a little larger than the pie tin.

Dice butter into 1.5cm dice and toss with flour and salt. Pulse in processor until it resembles breadcrumbs and no butter lumps are left. Mix water and vinegar together.

Add this to the flour butter and pulse a couple of times until a dough forms. Divide in 2 and press into a couple of round disc about 2 cm thick wrap in plastic and refrigerate overnight.

Let come to room temp for about 20 mins, roll out until about 4mm thick. Cut into circles about 1cm larger than the pie tins. Line tins.
