Place the almond paste and sugar in the bowl of a stand mixer and beat on medium speed for 1 1/2 to 2 minutes, until the almond paste is broken into tiny pieces.

Add the butter and continue to beat for another 2 minutes, until the mixture is well blended and slightly lighter in color. Scrape down the sides of the bowl with a spatula.

Add the egg and yolk and blend well. Add the orange blossom water and beat another 15 seconds to blend. Scrape down the sides of the bowl.

Add the flour and salt. Turn the mixer to the lowest speed and blend slowly, just until there are no more patches of flour.

Remove the bowl and stir gently a few times with the spatula to make sure there are no patches of unincorporated flour or butter lurking near the bottom of the bowl.

Line baking sheets with parchment paper.

Spoon half of the dough into a pastry bag fitted with a star tip. Pipe rosettes on a prepared baking sheet, spacing the cookies about 1 inch apart.

Alternatively, use a cookie press according to the manufacturer's instructions.

The rosettes should be about 1/2-inch thick and about 1 3/4 inches in diameter.

Repeat with the remaining dough.

Chill the sheets in the refrigerator for 30 minutes.

Preheat the oven to 350°F and position two oven racks in the upper and lower thirds.

Bake the cookies, switching the sheets between the racks and rotating each front to back halfway through, for 15 to 20 minutes, until the cookies are rich, golden brown around the edges and across the bottom.

Transfer to a cooling rack.

Immediately use the rounded handle end of a wooden spoon to make a depression in the center of each cookie about 1/2 inch across.

Be careful not to push so hard that you crack the cookie or break through to the baking sheet below.

Let the cookies cool completely.

Place the chopped chocolate and cream in a microwave-safe bowl and microwave on low for 30 seconds.

Stir the mixture. Heat again for 30 seconds and stir until smooth. If there are still lumps, heat again for 30 seconds.

Once smooth, spoon a little chocolate into each depression in the cookies.

Allow the filling to cool and set completely.
