To make the pastry, put the sugar, almonds and
flour into a blender or food processor and blend
at full speed for a few seconds. Add the butter
and work again until just blended. The mixture
should resemble fine breadcrumbs.
-
Add the egg and
egg yolk, the lemon zest, water and salt. Work
again until the pastry balls. Wrap in Clingfilm
and refrigerate for 2 hours.
-
Preheat the oven
to 190°C/375°F/Gas mark 5. Roll the chilled
pastry out and use to line a 20cm/8in
loose-bottomed tart tin. If it breaks it can be
repaired by pressing with your fingers.
-
Make the
shell as even as possible, with a double
thickness round the edges and pushed right up to
the top as it will shrink as it bakes. Be
careful to press into the bottom edges to
eliminate air between the tin and the pastry.
-
To
make the filling, put the butter, sugar, almonds
and breadcrumbs into the blender and work
briefly to mix. With the machine running on full
speed, add the egg and almond essence until
combined to a smooth paste.
-
Put the shell on a baking tray, prick the base
with a fork and line with aluminum foil. Fill
with baking beans and bake blind for 10 minutes.
-
Remove the foil and beans and leave to cool
slightly, then fill the base with a layer of
raspberry jam. Cover this with the almond paste.
Scrape the surface smooth and level.
-
Return to
the oven and bake for 25 to 30 minutes, until
risen and lightly browned.
