For
Galette des Rois, I prefer the almond cream stuffing ... not the
frangipane cream, just the almond cream one... It is has also
nothing to do with apple stuffing. This last one is not a galette
any more, it is an excellent apple pie.
The puff pastry making technique is quite difficult for newbe.
I therefore recommend getting a ready to use one. Frozen or chilled
does the job. Just allow plenty of time ( 2 hours ) to unfreeze.
Here we go. You’ve done or obtained some puff pastry. 450g
should be enough.
You’ll have to prepare the almond cream :
100
grams grounded almond, mix with same weigh of caster sugar. Add
100 grams of creamed butter and add 2 or 3 eggs. Smooth it all
with a spatula (you can use a mixer to fluff it)
Add a flavour : rum or bitter almond extract. Optionally "lier"
with a little bit of "crème pâtissière".
Background
knowledge break : The frangipane cream.
The
frangipane cream is actually a common base for a variety of pastry
creams. The sweet frangipane is made of : 2 litters milk, 325
grams caster sugar, 3 eggs and 4 yolks, 100 grams flour, 50 grams
rice starch, 20 grams starch. One mixes all ingredients, pour
the milk on it and bring to the boil for thickening it. In our
example, the pithiviers, one will flavour with rum. Eventually,
we’ll add fragipane to almond cream.
Back
to business...
You
will flatten the pastry and cut off tow discs ( one slightly larger
). You’ll flip over those discs ( for a better raise ).
Prepare a gold mix : an egg yolk added with its weigh of water
a pinch of sugar and pinch of salt.
Lay the almond cream on the small disc centre. The cream should
be dense, not flowing.

See
pastry assembly pictures: clic the pics
Brush
lower disc side with gold mix.
Place the second disc on top.
Make the sides stick while pressuring them with thumb. Also “chiqueter”
: using a knife, do small cuts on the sides.
Cut off a small hole in the top disc centre : It is the “cheminée”.
( This will avoid sides to break apart when steam is created in
oven. )
Brush top disc and decorate it.
I can not understate how important it is to leave the galette
( le pithiviers ) in a cool place for at least one hour. Then
finish up decoration. Give an other gold brush.
Moisturise a cooker tray. ( Do not grease it ! ). Lay a sheet
of greaseproof paper on it and the galette.
During cooking, you’ll brush the coloured surface with light
sugar syrup.
Cooking
: Quick
and limited.
Cooking
is fast. Preheat oven on 200°C. Start cooking and let the
puff develops for 10 minutes. Lower temperature to 180°C to
cook pastry thoroughly for a generous 20 minutes...

To
be enjoyed warm, listening to "Blue Tango" by old chap
Paolo Conte.
On can add lots of "fève" ( charm ) to keep all children
happy !
