Heat all ingredients apart from the water and pears to a simmer until sugar is dissolved.
1 bottle white wine, 250 g sugar, 1 lemon, juice and zest, 3 inch nob of ginger, 1 pinch salt
Add the pears and water to cover them, add a cartouche and simmer until pears are fork tender.
6 pears peeled, Enough water to finish covering pears
Drain and allow the fruit and poaching liquid to cool separately. Store cooked fruit in the poaching liquid after it has been cooled for up to 3 days or use right away.
For the tart, slice the pears in half and core them. Slice however you would like and use to garnish the tart. You likely will not use all 6 pears.
With the extra pears you can make pretty poire en cage, a pear puff pastry dish. Or you can just poach 3 for this recipe and only use them for the tart. Up to you.
