Lemon and lime custard tart


Lemon and lime custard tart
This is a delicious version of the classic French baker's "flan", with the twin flavours of lemon and lime.

It involves two different confectioner's custards poured one on top of the other. This gives an attractive layered effect when the tart is cut. Not just pretty, it is delicious.

Step by step recipe


Stage 1 - 5 min.
Lemon and lime custard tart
Roll out 700 g Sweetcrust pastry (pâte sablée) and line the tin or mould, following these tips.

Instead of a tin, here I am using a dessert ring 8 inches (20 cm) in diameter and 2 inches (5 cm) tall. This is in keeping with the French tradition of a "flan": small and fairly deep.

Stage 2 - 1 hour
Lemon and lime custard tart
Prepare 900 g Lemon Confectioner's Custard, then 900 g Lime confectioner's custard (pastry cream).

Note: For convenience, these two custards can be prepared the day before.

Pour the lime custard into the pastry case and spread in as even a layer as possible, using the back of a tablespoon, for example.

Stage 3 - 3 min.
Lemon and lime custard tart
Pour the lemon confectioner's custard on top and smooth the surface.

Stage 4 - 50 min.
Lemon and lime custard tart
Preheat the oven to 360°F (180°C). Bake the tart for about 50 minutes.

Do keep an eye on how both the top of the custard and the pastry are browning, and vary the cooking time if necessary.

Stage 5 - 30 min.
Lemon and lime custard tart
Leave to cool for 30 minutes, then remove the dessert ring and refrigerate the tart overnight.

Warning: the tart will still be very fragile at this stage, so you will need to manipulate it with great care to avoid it breaking.

Stage 6 - 10 min.
Lemon and lime custard tart
If you would like an attractive decoration for your tart, cut a few thin slices of lemon and lime. Give them a light candied finish by simmering in 200 g caster sugar with 40 g water on very low heat for about 10 minutes.

Stage 7 - 30 min.
Lemon and lime custard tart
Remove the slices from the syrup and leave to dry on a

wire rack or a sheet of cooking parchment.

Stage 8 - 5 min.
Lemon and lime custard tart
Arrange a few slices of candied lemon and lime on top of your tart, after glazing (if desired) with a brush just beforehand.

Stage 9

Serve cool, but not (too) cold.
Remarks
If you make the custards the day before (or even earlier), as suggested in stage 2, loosen them by adding 2 tablespoonsful of fresh cream and whisking in vigorously before pouring into the pastry case.

This tart is a fairly luxurious version, with its sweetcrust pastry case, but there's no reason you couldn't use a simpler pastry, such as plain shortcrust.

If you would rather have the green layer on top, simply pour the custards into the case the other way round.

For a smoother, richer version, replace half the milk in the confectioner's custard recipe with cream.
Keeping: Several days in the fridge, covered with plastic film.
Source: Home-made, but this recipe is affectionately dedicated to Seb, a (very) great fan of citrus flavours, who will no doubt recognise himself in it.
