If you want to bake meringues yourself, start with that. Bake them well in advance or the day before.
Turn on the oven to 200 degrees Celsius (fan/convection).
Wash the rhubarb, and cut it into slices of about 3-4 cm.
200 g rhubarb
Scrape the seeds out of the vanilla bean and mix them with cane sugar. Put the rhubarb pieces in a bowl with the vanilla sugar, and mix everything well together, before pouring it into an ovenproof dish. Also, feel free to put the empty vanilla bean in the dish to give extra flavor, and pour water into the dish. Bake rhubarb in the oven for 20 minutes at 200 degrees Celsius (fan/convection), and let them cool down completely in the refrigerator afterward before assembling the dessert.
1 vanilla bean, 80 g cane sugar, ½ dl water
Whip the cream together with vanilla sugar into a light foam. It should not be too firm, but still form soft peaks.
2 ½ dl whipping cream, 1 tbsp vanilla sugar
Crush the meringues, save a couple for decoration. Fold the remaining meringue pieces into the vanilla whipped cream.
40 g meringue kisses
Assemble the dessert layer by layer. First a layer of vanilla/meringue whipped cream, then a layer of baked rhubarb, then whipped cream, and finally rhubarb. Also, feel free to use some of the syrup from the bottom of the dish, it tastes wonderful. Garnish optionally with a few mint leaves and meringues on top and serve immediately.
