Preheat the oven to 100°C and line 2 baking sheets with baking parchment.
In a large, grease-free bowl with an electric mix, or the bowl of a stand mixer, whisk the aquafaba for 10 minutes, until the mixture has stiff peaks. Add the vinegar and whisk for one minute more, then start adding the sugar, very slowly, 1 tablespoon at a time, whipping well between each addition.
Once all the sugar has been used up and the meringue is smooth, stiff and glossy, spoon or pipe 8 equal-sized meringues onto the prepared baking sheets, then transfer to the oven to bake for 2 hours. After this time, turn off the oven and open the door slightly, but leave the meringues inside for a further 45–60 minutes.
Test the meringues are done by tapping the bases – they should be dry to the touch and sound hollow. The meringues can be used straightaway or kept in an airtight container for up to a week.
Bake for 2 hours, then turn off the oven and leave meringues inside with oven door open slightly for a further ¾–1 hour. Make sure they are very dry and sound hollow when you tap the base. Use straightaway or transfer to an airtight container for up to a week, until ready to use.
To make the coconut whipped cream, scoop the hard, thickened coconut cream from the top of the cans into a large bowl, being careful not to add any thinner liquid.
Add the icing (confectioners’) sugar and vanilla extract, and whisk with an electric beater for about 2 minutes, until fluffy.
Refrigerate for 30 minutes before using.
Serve the meringues topped with coconut whipped cream and the fruit of your choice.
