3/4 cup sugar
1/3 cup water
8 egg yolks, room temperature
1 cup (2 sticks) unsalted butter, cut into
10 pieces, cool room temperature
Flavoring (see Variations)
Cook sugar and
water in heavy small saucepan over low heat until sugar dissolves, stirring
occasionally. Increase heat to medium-high and boil without stirring until
candy thermometer registers 248 degrees F. (firm-
ball stage), brushing down sugar
crystals from sides of pan with pastry
brush dipped in water, approximately
4 minutes. Meanwhile, beat yolks
with electric mixer until well blended and
light.
As soon as
syrup is ready, gradually beat into yolks in thin, steady stream. Beat
mixture at high speed until completely cool and thick, scraping down sides
of bowl once or twice, about 20 minutes. Reduce speed to medium-low. Add
butter pieces 1 at a time and beat until incorporated. (Can be prepared 1
week ahead and refrigerated or 3 months ahead and frozen. Cover tightly.
Before continuing with recipe, bring buttercream to room temperature. Work
with spatula until completely smooth.) Using wooden spoon or paddle beater
(not whisk), very gradually mix in flavorings.
Makes about 2 1/2 cups.

Tips
• Because
buttercream is rich, it is best used on light cakes such as
génoise. Spread
buttercream thinly.
• Cakes
filled and frosted with spirit-flavored buttercream should be
served the
same day; otherwise the taste of the spirits will diminish.
Other types
can
be prepared up to 3 days ahead, covered tightly
and refrigerated.
• To
facilitate cutting, chill cake for about 1 hour, then let stand at room
temperature briefly so that the buttercream can soften slightly.
• Do not add
flavorings too quickly or more than recommended amount,
or the buttercream
will separate. To correct this, chill buttercream 30 minutes. Set bowl of
buttercream over pan of warm water for a few
seconds. Remove from heat. Beat
with wooden spoon until smooth.
If necessary, rewarm again as above. If
buttercream is still not smooth,
melt 2 tablespoons butter and gradually
beat into buttercream.
• Cakes may
be garnished with fruit, nuts, grated chocolate or small
candies to match
flavor of buttercream. Try fresh raspberries with
Framboise buttercream, for
example.

Make orange curd: In a small
heavy saucepan whisk together yolks
and sugar and whisk in orange juice,
butter and a pinch of salt. Cook
the mixture over moderately low heat, whisking,
until it just reaches
boiling point, 5
to 7 minutes (do not let boil), and
strain through a fine
sieve into a bowl. Whisk
in lemon juice and cool the
curd, its surface covered with plastic wrap.
Chill orange curd, covered,
until cold, at
least 4 hours, and up to
2 days.
