-
Preheat the oven
to 325°F/170°C/gas 3. Line three cookie sheets
with parchment paper.
-
Sprinkle the almonds on a
large baking sheet. Toast for 7 minutes, or until
lightly golden.
-
Lower the oven temperature to
275°F/140°C/gas 1. Process the almonds in a food
processor until very finely chopped.
-
Beat the egg
whites, superfine sugar, and vanilla sugar in a
double boiler over barely simmering water with an
electric mixer at high speed until stiff peaks form.
-
Add the orange zest and juice. Remove from the
heat. Use a rubber spatula to fold the almonds and
bread crumbs into the batter.
-
Drop teaspoons of
the batter 1 inch (2.5 cm) apart onto the prepared
cookie sheets.
-
Bake, one sheet at a time, for
20-25 minutes, or until pale golden. The macaroons
should still be soft but will harden while cooling.
Transfer to racks to cool.
-
Glaze: Heat the
marmalade in a small saucepan and drizzle over the
cooled macaroons. Set aside.
-
Melt the chocolate in
a double boiler over barely simmering water. Drizzle the chocolate over the tops.
