-
2
You must use 1 1/2 cups all purpose flour if you are making petite fours.
-
3
FOR THE CAKE: In a large bowl combine eggs and sugar.
-
4
Stir for a minute, or until they are just combined.
-
5
Set bowl over a saucepan containing 1 or 2 inches of hot water.
-
6
Water in pan should not touch bowl; nor should it ever be allowed to boil.
-
7
Place saucepan containing bowl over low heat for 5 to 10 minutes, or until eggs are lukewarm.
-
8
Heating the eggs help them whip to greater volume.
-
9
It is not necessary to beat them continuously as they are warming.
-
10
They should, however, be lightly stirred 3 or 4 times to prevent them from cooking at bottom of bowl.
-
11
When eggs feel lukewarm to your finger and look like a bright yellow syrup, remove bowl from heat.
-
12
Begin to beat, preferably with an electric mixer.
-
13
Beat at high speed for 10 to 15 minutes, scraping sides of bowl with a rubber spatula when necessary, until syrup becomes light, fluffy, and cool.
-
14
It will almost triple in bulk and look much like whipped cream.
-
15
It is the air beaten into the eggs that gives genoise its lightness.
-
16
Sprinkle flour, a little at a time, on top of the whipped eggs.
-
17
Fold in gently, adding slightly cooled, clarified butter and vanilla.
-
18
Folding can be done with electric mixer turned to lowest speed, or by hand.
-
19
Best done by hand.
-
20
Be especially careful not to overmix.
-
21
Pour batter into prepared pans, of your choice above.
-
22
Bake in preheated oven 25 to 30 minutes, or until cakes pull away from sides of pans and are golden brown and springy when touched lightly on top.
-
23
Remove from pans immediately and cool on cake rack.
-
24
Almost all petits fours freeze well before they are iced.
-
25
Not all petits fours require an icing glazed with fondant.
-
26
This is tricky to make and use.
-
27
Traditionally, petits fours are served in small, individual paper cases.
-
28
FOR THE PETITS FOURS: To make the little iced geometric cakes most people think of as petits fours, bake a sheet of genoise for petits fours in an 11 x 16 jelly-roll pan.
-
29
The baked sheets of cake should not be more than 3/4 inch high.
-
30
If possible, bake the cake a day ahead so it can be cut more easily.
-
31
Cut the cake in half, making 2 layers, each 8 x 11.
-
32
Spread 1 layer with a thin layer of apricot or raspberry jam.If desired, any butter cream may be substituted for jam.
-
33
Place second layer on top of first.
-
34
If butter cream is used, chill cake slightly.
-
35
Brush top with hot apricot glaze.
-
36
Trim off all crisp edges.
-
37
Allow glaze to dry for a few minutes.
-
38
Then, using a long knife with a serrated edge, cut cake into even 1-inch shapes; cubes, rectangles, triangles, etc.
-
39
A ruler may be used for making cakes of equal size.
-
40
Rounds can be cut with a cooky cutter, although there is much waste.
-
41
Wipe knife edge off with a damp sponge after each slice.
-
42
Place 1/3 of the little cakes on a cake rack, leaving some space between them.
-
43
Set rack in a shallow pan.
-
44
Warm the fondant or mock fondant.
-
45
Flavor it with vanilla or a liqueur.
-
46
When lukewarm, spoon or pour plenty of icing in the center of each cake so that it will run down and coat sides.
-
47
Excess will drip into pan under rack.
-
48
Scrape up drippings and return them to pan of vanilla fondant.
-
49
Add coffee to flavor fondant.
-
50
Reheat what is now coffee fondant to lukewarm.
-
51
If necessary, thin it with a little syrup or water.
-
52
Arrange another third of the cakes on a second cake rack.
-
53
Place rack in shallow pan.
-
54
Cover tops and sides of the little cakes with coffee fondant.
-
55
Scrape icing up and return in to pan.
-
56
Flavor remaining coffee fondant with chocolate.
-
57
The chocolate flavor and color will now dominate.
-
58
Place remaining cakes on a third rack and cover with chocolate fondant.
-
59
Allow all the cakes to dry about 10 minutes.
-
60
Loosen from racks with a spatula.
-
61
Place each in a tiny paper case and, if desired, decorate.
-
62
Simple decorations can be very beautiful: crushed bits of crystalized violets or green pistachio nuts; or prepare ad additional 1/2 cup of fondant, coloring it as you like.
-
63
It should be a little thicker than the fondant used for pouring.
-
64
Fill a paper cornucopia with the colored fondant and cut a tiny hole in the pointed end.
-
65
Make dots, lines.
-
66
scrolls; a variety of patterns can be improvised.
-
67
Each little cake needs no more than the tiniest bit of decorations.
-
68
FOR THE APRICOT GLAZE: Heat apricot jam in a saucepan until it is boiling.
-
69
Stir in preferred flavoring.
-
70
Use glaze while it is hot.
-
71
Mock Fondant: Much easier to make than real fondant, and more quickly prepared, this recipe provides an excellent substitute if you have on hand a jar of the basic simple syrup, which keeps almost indefinitely.
-
72
For best results, pour mock fondant over cake which has first been lightly brushed with hot apricot glaze.
-
73
BASIC SIMPLE SYRUP: 2 1/2 cups sugar 3/4 cup white corn syrup 1 1/4 cups water Combine sugar, corn syrup, and water in a large saucepan.
-
74
Stir over low heat until sugar is completely dissolved.
-
75
When it looks clear, wash down sides of saucepan with a brush dipped in cold water.
-
76
Place lid on saucepan for 5 minutes so that steam will further dissolve any sugar crystals.
-
77
Remove lid.
-
78
Raise heat.
-
79
Boil for 5 minutes without stirring.
-
80
Cool syrup, pour into jars, and cover tightly.
-
81
Store for future use.
-
82
Note: if sugar has not been thoroughly dissolved, the syrup, after a week or even less, may form large crystals in the bottom of the jar.
-
83
The presence of crystals will not hurt the syrup, but it is wasteful, because the more crystals the less syrup you will have.
-
84
MOCK FONDANT: 1/2 cup cooled basic simple syrup 1 1/2 cups sifted confectioners' sugar (approximately) 1 teaspoon egg white 1 teaspoon melted butter Place syrup in a saucepan.
-
85
Add enough sifted confectioners' sugar to make a fairly stiff paste.
-
86
It should be a bit too thick to pour or spread by itself.
-
87
Place saucepan over low heat and warm, stirring constantly till fondant is lukewarm.
-
88
Be careful not to overheat, or the icing will not be shiny.
-
89
Beat in a teaspoon each of egg white and melted butter.
-
90
If icing is still too thick, add additional syrup or flavoring liquid to thin it.
-
91
If it becomes too thin, add more confectioners' sugar.
-
92
This is enough mock fondant for the top of a 9-inch layer cake.
-
93
Flavor with any one of the following, or any flavor of your choice: 1 ounce melted unsweetened chocolate 1 tablespoon extra-strong coffee 2 tablespoons rum 2 tablespoons any liqueur 1 teaspoon vanilla.
