Onion Tarte Tatin

30ml + 30ml butter
1 clove garlic, minced
6 onions, halved horizontally
100ml sugar
60ml water
30ml balsamic vinegar
5ml thyme leaves
5ml salt
1 x 400g roll Today puff pastry

Preheat your oven to 200℃.
Put a wide-bottomed pan on medium-high heat and add 30ml butter to melt.
Add the garlic and onion halves cut-side down.
Cook the onions until they have caramelised and softened slightly (about 10 minutes).
Gently remove the onions from the pan and set aside.
Add the sugar and water to an ovenproof pan over medium heat.
Cook, swirling constantly, until the sugar dissolves – DO NOT stir!
Turn the heat up to high and cook undisturbed (no stirring!) for 5 minutes or until it turns to a golden caramel – this happens instantly!!
Remove from the heat and add the balsamic, thyme, salt and 30ml butter.
Return to the boil and swirl to combine.
Arrange the onions cut-side down, trying to fit in as many halves as you can.
Place the puff pastry on a lightly floured work surface and roll it slightly wider.
Now cut a circle that is 1cm larger than the diameter of your pan.
Place the pastry circle on top of the onions and tuck in the edges so that it forms a “basket” for the onions.
Cut a very small hole in the centre of the pastry and bake in the oven for 30 minutes.
Remove from the oven and cover with aluminium foil to prevent burning.
Return to the oven and bake for another 20 minutes until the pastry is cooked through.
Remove the tart from the oven and leave to stand for 10 minutes.
Place a flat plate/wooden board over the pan and carefully invert the tart.
Season with salt and pepper to serve.
