Directions

Preheat the oven: to 160°C
Make the posset: Heat up the sugar, crème fraîche and double cream over low heat in a saucepan until steaming, whisking to ensure no lumps. Grate in the zest of three lemons, then squeeze in the juice of one lemon. Stir well, then decant into 4 glasses. Leave to cool, then leave in the fridge to set for 3 hours, up to overnight.
Make the thyme sugar: Rub the thyme leaves and the vanilla pod seeds into the sugar, massaging with your fingers so the flavours of both infuse the sugar.
Bake the rhubarb: Toss the rhubarb in the thyme and vanilla sugar mix (note - you may not use all of the sugar mix, season to your sweetness preference. We used about a handful of sugar to roast our rhubarb. The rest of the thyme and vanilla sugar can to stored to be used for other things!) Then squeeze the juice of one lemon over the rhubarb and lay it in a baking tray. Roast for 15 minutes, until soft, but not falling apart.
Serve: Once the posset has set, serve with some of the rhubarb on top.

How to cook rhubarb?

What is a posset?

Posset is similar to a custard in texture, but it contains no eggs, or any gelatine, or corn-starch to thicken it. This traditional British dessert is set by heating a dairy product (like double cream or crème fraîche) then adding acidity from a citrus fruit.
