Using the dough hook of the
stand mixer, combine the two types of flour and the salt, adding the water and
cream a little at a time. Shape into a ball and let rest in the refrigerator.
Roll out the dough and insert the butter sheet. Close up the dough package and
give it its turns.
Cream the softened butter with
the sugar, add the ground almonds and flour then gradually add the eggs. Stir
the room-temperature pastry cream, combine the two mixtures then add the warmed
rum.
Prepare a traditional pastry
cream.
Sauté the IQF blackcurrants
with the sugar and blackcurrant liqueur in a well-preheated pan with the sugar
and blackcurrant liqueur to extract the juice. Be careful that the berries
remain whole. Drain and set the juice aside.
Combine the ingredients and
set aside.
Combine the fondant, blackcurrant juice, and glucose syrup and heat to 150°C. Add the colouring and pour onto a Silpat mat. Let cool. Grind in a food processor, then add the ground dried hibiscus flowers. Store in an airtight container to protect from moisture.
Perform 5 single turns, letting the dough rest between turns. Roll out the
puff pastry to a thickness of 2 mm and cut out Ø28 cm circles. Let rest.
Pipe 300 g of frangipane into Ø20 cm circles on parchment paper using a 12 mm
plain tip. Add 70 g of drained sautéed blackcurrants, then pipe in 50 g of
frangipane. Smooth the surface and freeze.
Place a frangipane insert in the centre of a puff pastry circle. Brush the
edges with water to moisten. Top and seal with another puff pastry circle,
giving it a quarter turn for even shrinkage. Optionally, recut the galettes to
Ø26 cm and prick.
Turn the galettes over, brush the surface with water to moisten slightly and
sprinkle with the sugar/cornmeal mixture. Turn over onto a baking sheet lined
with baking paper and bake in a 170°C convection oven for approximately 45
minutes.
Turn the galettes over, sprinkle with the hibiscus opaline, and bake for
another 5 minutes. After baking, brush the surface of the galettes with a thin
layer of reserved blackcurrant juice and let cool.
