Small handful toasted slivered almonds, if desired
Pre-heat oven to 140°C (120°C fan-forced) and line a baking tray with baking paper. Trace an 18cm (7”) circle on baking paper, then flip paper over to avoid marking pavlova.
Place egg whites and cream of tarter in a free standing mixer and whisk on medium speed until frothy.
Slowly add caster sugar, teaspoon by teaspoon, while continuing to whisk (this process should take approximately 10-12 minutes).
Turn mixer up to high speed and continue whisking until mixture transforms into glossy thick meringue and stiff peaks form (approximately 2 minutes). If you rub a little meringue between your fingers it should feel completely smooth, with no grittiness of undissolved sugar.
Sprinkle sifted cornflour over meringue, then fold in along with vinegar and rosewater.
Spoon meringue onto baking paper within the drawn 18cm (7”) circle, then use a palette knife to shape the sides of the pavlova and create a small nest in the middle.
Place tray in oven on bottom shelf and turn the oven down to 130°C (110°C fan-forced). Bake for 90-100 minutes, then turn oven off without opening the oven door and leave pavlova in the oven for 4-6 hours to allow the pavlova to cool down slowly and prevent collapse.
Hibiscus Poached Pears
Place water, spices and petals into a large pot and allow to simmer 5-10 minutes for flavours to infuse.
Add pears and simmer again for 10-15 minutes, turning intermittently. When poached well, the pears should maintain their shape, but be soft enough to be eaten with a spoon.
Allow pears to cool in pot, turning intermittently to ensure an even colour develops.
When cooled, remove pears, strain liquid and return liquid to the pot, along with sugar and lemon juice to simmer for another 15-20 until reduced to a syrup.
Pears and syrup can be kept refrigerated for 1-2 days prior to serving.
Gently whisk together cream and sugar to soft peaks, then spread over pavlova.
Decorate with a few poached pears, drizzle with syrup and sprinkle with toasted almonds. Serve with remaining extra pears.
