Filling:

40g cornflour
50g unsalted butter, diced

Method:
Filling*:
Grate the lemon zest into a heatproof bowl, with the juice from the lemons, and the cornflour. Mix together until the mixture is smooth. Heat 400ml of water until just boiling, and then pout onto the lemon juice and cornflour.
Remove the mixture from the heat, beat in the egg yolks gradually, then beat in the butter bit by bit, then beat in the caster sugar. You should now be left with a smooth lemon curd (smooth apart from the zest, obviously).
Meringue:
Whisk the egg whites in a bowl until they form stiff peaks. Gradually whisk in the sugar, a little at a time, whisking well between each addition, until very stiff and shiny. If you feel a little of the mixture between your fingers there will be no grittiness if the sugar has dissolved into the egg whites.
Make sure that you're making the meringue mixture at the same time, and when reaching the finishing point for both, pour the curd mixture into the tart case. You're to place the tart onto a pre-heated oven tray, so I already had my tart on a sheet of baking parchment. This allowed me to pull it straight onto the tray when required.
*Now for the advice bit: bread makers weigh everything. When we say 4 eggs whites, we generally give an equivalent weight, because obviously not all eggs are the same size. Herein lies the problem with the recipe for me. My lemon curd was a little too loose, and I think this is because the quantity of lemon juice isn't specified exactly. When you make the curd, make sure that it is thicker than perhaps you'd expect it to be. As soon as it started to thicken, I removed it from the heat and gave it a thorough beating :0). Perhaps given that I was then to add further liquids (in the form of the beaten egg yolks and the butter which would melt) I should have ensured that the first stage of the curd was much thicker than it needed to be. I would also say, make sure you have a deep enough tart case! I made a very short tart, which of course meant that I had a very fine layer of lemon in the finished product. It also left me with a little spare lemon curd (hurrah). Personally I preferred it that way, but it really is a lemon tart then, not a lemon meringue pie. I think you also end up with far too great meringue to curd ratio. Having said that, the tart was delicious, and very popular.
