Begin by pre heating your oven to 190 degrees Celsius. Lightly blitz your oats then add in your melted butter and sugar. Stir until all oats are evenly coated and when you press the back of a spatula down the oats should begin to hold the shape- add more butter if necessary until this happens. Next evenly spread your oats over the base of the tin and up the sides, pressing down firmly so that the oats stick together and form and the case. Let this rest in the fridge for half an hour which will help it hold it’s shape when baking. Once chilled transfer to the oven and bake for fifteen to twenty minutes or until golden then remove and allow to cool completely.
Next get the crème patissiere made. Begin by adding both the milk and vanilla pod with the seeds in a saucepan over a medium heat, bring the milk almost to the boil then set to one side.
In a separate bowl whisk together the egg yolks and sugar until the mixture begins to lighten and turn fluffy. Next add in the sifted flour, folding it into the egg and sugar mixture until it’s smooth. Once the milk has cooled for a minute or two gradually pour into the egg, sugar and flour mixture, whisking the whole time to ensure the sauce is smooth ands there’s no lumps. Next pour the mixture back into the saucepan and cook over a medium heat, stirring with a wooden spoon the whole time to avoid lumps forming. Cook until you have a thick smooth sauce that begins to hold it’s shape. Once cooked remove from the heat and cover with clingfilm to avoid a skin forming, transfer to the fridge once cooled. If lumps form you can pass it through a sieve.
For the charred nectarines, simply heat a griddle pan for several minutes over a high heat and place the nectarine flesh side down, allowing them to char for 3-4 minutes, then carefully turn and cook skin side down. They will stick a little which I don’t mind but you can always cook them on a sheet of parchment paper to avoid this.
Now all that’s left is to put everything together. Spoon the crème patissiere into the oat crust then place the charred nectarines on top, some face down some flesh side up. Sprinkle over your selection of edible flowers and serve.
This will keep refrigerated for several days.
