1 Prepare the dough: preheat the oven to 180 ° C or thermostat 6. Blanch the yolks and sugar with a little water (reserve the whites). Mix the flour and butter with your fingers, cut into small pieces to obtain a sandy consistency. Pour the liquid mixture in the middle of this sand. Form a ball with the palms and countersink 1 or 2 times. Spread the dough directly on baking paper and garnish the pie dish with the dough pricked with a fork. Place baking paper and cover with dried beans. Cook for 10 minutes (the dough should not color or very little).
2 Make the cream: in a bowl, combine 2 whole eggs and 2 yolks (put the whites aside) the crème fraîche and sugar. Then add the juice of the 2 lemons as well as their very finely grated zest. Take the dough out of the oven, remove the beans and add the mixture. Bake for 30 minutes.
3 During this time, prepare the meringue: use the 4 egg whites, add a pinch of salt and beat until stiff. When they are firm, slowly add the icing sugar, continuing to beat.
To finish
When the pie is cooked, spread the meringue over the lemon cream and cook for another 10 minutes so that the meringue is lightly browned. Leave the pie in the oven off for 40 minutes for a crunchy meringue.
