Ingredients:
sablé (cookie dough):
Zest of 1 lemon or orange or lime (optional)
1 heavy pinch of salt
90g (3oz) icing sugar
2 egg yolks
80g (2.5 oz) almond meal
125g (4 oz) of all purpose flour
crème patissière :
450g/1lb whole milk
4 egg yolks
120/4oz sugar
60g/2oz corn starch
60g/2oz corn starch
60g/2oz butter
1 tbsp vanilla extract
Mirabelles cut in half
Procedure:
For the pastry cream: Dissolve cornstarch in 1/4 of the milk, combine rest of the milk with sugar and bring to a boil, whisk eggs in the cornstarch mixture, pour 1/3 of the boiling milk over the eggs, then return milk and milk+egg mixture to the heat. Boil for about 1 minute whisking. It will look lumpy when it starts boiling, keep whisking until smooth then remove from the heat and whisk in butter, vanilla. Transfer to a cold container, press some plastic film directly on the cream and refrigerate.
For the sablédough: Put soft butter (zest if desired) and sugar in the bowl of a stand up mixer fitted with the whisk attachment. Whisk at low speed until the sugar is incorporated then increase the speed and go for a couple of minutes until the mixture is fluffy. Stop the mixer and scrape the bowl if you see that the butter is sticking to the sides of the bowl. Add the yolks, one at the time and mix until incorporated. Stop the mixer add the almond meal, whisk until incorporated, then finally the flour. Whisk 10 seconds at highest speed after having added the flour. Stop and transfer mixture into a piping bag fitted with a round tip. Preheat the oven at 180C/350F. Line a cooking sheet with parchment paper or a silicon mat. Butter the inside of some ring molds. Pipe the dough about 1 cm high inside metal ring molds and bake for about 12 minutes. The cookies should be golden, not too dark. Take out of the oven and gently remove the ring molds while still hot. Let the cookies cool and wipe the ring molds clean.
