1. Begin by sifting the flour, icing sugar and a pinch of salt. Next, chop your butter into small cubes and, if you have a magimix, pulse until it resembles fine crumbs.
Add the yolks and 1-2 tbsp water, then pulse again until the pastry comes together. Remove and gently knead the dough before wrapping in cling film and leaving to chill in the refrigerator for 30 minutes.
2. Once the pastry has chilled, roll it into a thin layer (using flour to dust) to line a 25cm diameter, 3cm deep loose bottomed tart tin. Prick the base of the tart with a fork and put it into the fridge to chill for 25 minutes.
Preheat the oven to 200ºC/fan 180ºC/gas 6/395ºF and place a baking tray in the oven to pre-heat as well.
3. Line the tart tin with baking paper and baking beans, and bake for 12-15 minutes until the edges are very lightly browned. Remove the baking paper and beans, and bake for another 4 minutes. Remove once again, brush with the whisked egg white, and return to the oven for a final two minutes. Remove from the oven and reduce the heat to 120ºC/fan 100ºC/gas ½/250ºF.
For the filling
1. Begin by grating the zest from the lemons and set aside, then squeeze the juice from all of the lemons and limes (to achieve 150-175ml of liquid). In a separate bowl, lightly beat the eggs and sugar together by hand (you don’t want the eggs to be frothy), add the citrus juice and cream, and sieve the resulting mixture. Add the lemon zest last.
2. To bake the tart, to avoid spilling, Rick Stein suggests placing the baking sheet back in the oven, placing the pastry case on the tray and pulling the shelf half way out of the oven. Pour the filling into the pastry case, slide the shelf back into the oven and cook for approximately 50 minutes (until just set). The mixture should be quite wobbly in the centre still but will continue to firm up after it comes out of the oven. Remove from the oven and leave to cool (don’t refrigerate). Dust with icing if you feel inclined and serve on the same day if you can.
