Firstly make your creme pat – simply heat the milk with the vanilla pod in (scrape out the seeds first and add to the milk). When just about to boil, pour onto the egg yolks, sugar and flour which you have whisked together briefly. When combined, return to the pan and whisk constantly over the heat until thickened. Pour into a wide dish to hasten cooling and cover the surface directly with cling film and leave until room temp. When cooled fully, spoon out generous teaspoons onto some waxed paper or greased foil sat on a freezer safe plate and freeze for 2-3 hours until solid.
Next, roast one long stalk of rhubarb cut into lozenges (or diamonds) tossed with a light coating of caster sugar (about 1 heaped tbsp) at 180°C for 30- 40 minutes. Don’t move them about or add any liquid as they will turn into a mush. When cool, chose 6 pieces to top the cakes with and chop the rest finely.
