Preheat your oven to 100ºC and line a baking tray with baking paper.
Whip the egg whites until fluffy. Add a 1/4 of the caster sugar and whip until the sugar dissolves. Keep adding and whipping until all of the sugar has dissolved. The mixture should be glossy.
Add the Lupi Extra Virgin Olive Oil, cardamom, orange zest, cornflour, and vinegar and whip until just combined. Place teaspoon-full blobs on the baking tray and bake for an hour in the oven.
Remove from the oven and cool on the tray. Serve with crème fraîche or yoghurt. Can be stored in an airtight container for 2 weeks.
