Meringue

rom Wikipedia, the free encyclopedia

Meringue with whipped cream.
Meringue (pronounced /məˈræŋ/[1]) is a type of dessert made from whipped egg whites and sugar. Some meringue recipes call for adding a binding agent such as cream of tartar or the cornstarch found in confectioner's sugar. Meringues are often flavoured with vanilla and a small amount of almond or coconut extract. They are light, airy and sweet.

[edit] History

The notion that meringue was invented in the Swiss town of Meiringen[2] by an Italian chef named Gasparini is contested. It is more probable that the name meringue for this confection first appeared in print in François Massialot's cookbook of 1692.[3] The word meringue first appeared in English in 1706 in an English translation of Massialot's book. Two considerably earlier seventeenth-century English manuscript books of recipes give instructions for confections that are recognizable as meringue, though called "white biskit bread" in the book of recipes started in 1604 by Lady Elinor Fettiplace (c. 1570 - c. 1647) of Appleton in Berkshire (now in Oxfordshire),[4] or called "pets" in the manuscript of collected recipes written by Lady Rachel Fane (1612/13 - 1680), of Knole, Kent.[5] Slowly baked meringues are still referred to as "pets" (meaning farts in French) in the Loire region in France due to their light and fluffy texture.[6]

[edit] Type of meringue

There are several types of meringue, the sweetened, uncooked beaten egg whites that form the "islands" of Floating Island (also known in French as île flottante), the partly cooked toppings of lemon meringue pie and other meringue-topped desserts, and the classic dry featherweight meringue. Different preparation techniques produce these results.
  • French meringue is the method best known to home cooks. Fine white sugar is beaten into egg whites.
  • Italian meringue is made with boiling sugar syrup, instead of caster sugar. This leads to a much more stable soft meringue which can be used in various pastries without collapsing. In an Italian meringue, a hot sugar syrup is whipped into softly whipped egg whites till stiff. This type of meringue is safe to use without cooking. It will not deflate for a long while and can be either used on pies and Baked Alaska, or spread on a sheet and baked for meringues.
  • Swiss meringue is whisked over a bain-marie to warm the egg whites, and then whisked steadily until it cools. It is then baked.

[edit] Chemistry

Beaten egg whites
When egg whites are beaten, some of the hydrogen bonds in the protein break, causing the protein's structure to unfold. This change in structure leads to the stiff consistency required for meringues. The use of a copper bowl, or the addition of cream of tartar is required to additionally denature the proteins to create the firm peaks, otherwise the whites will not be firm.
When beating egg whites, they are classified in three stages according to the peaks they form when the beater is lifted: soft, firm, and stiff peaks.
Sugar substitutes are not useful in meringue. The sugar is necessary to the structure.
Egg whites and sugar are both hygroscopic (water-attracting) chemicals. Consequently, meringue becomes soggy when refrigerated or stored in a high-humidity environment. This quality also explains the problem called "weeping" or "sweating", in which beads of moisture form on all surfaces of the meringue. Sweating is a particular problem for French meringues in which the granulated sugar is inadequately dissolved in the egg whites, and for high-moisture pie fillings.

[edit] Uses

Three meringue mushrooms standing on a table. Each mushroom was made from two stiff, dry, baked pieces of meringue that were attached with a small amount of melted chocolate. The realistic "dirty" color is created by sprinkling it with cocoa powder.
Meringues eaten like biscuits are baked at a very low heat for a long time.[7] One name for them is "Forgotten Cookies"[8] as they can be left in a gas oven for long periods of time after the cooking is done. They are not supposed to be "tanned" at all, but they need to be very crisp and dry. They will keep for at least a week if stored in an airtight container.
Meringue can be used as the basis for various other desserts including angel food cake, pavlova, Baked Alaska, Queen of Puddings, Key lime pie, Eton mess and lemon meringue pie. In these cases, the meringue may be cooked at a higher temperature for a shorter amount of time, resulting in a soft meringue with slightly browned peaks on top.
Another dish is "Meringue de Angel", which consists of shortbread biscuits layered with meringue and lemon curd, topped off with drizzled lemon glaze. Variations include raspberries, peaches, mangos, blueberries, blackberries, pineapple, papayas, honeydew, oranges, cantaloupe, or cherries and strawberries.
Meringue may be used for decoration. It can be formed into whimsical shapes, like mushrooms, or piped into a crisp basket that is baked and filled later with cake, fruit, or flowers.

A meringue tart is a sponge cake covered with meringue.

[edit] Nutritional content

Meringue is a fat-free food, because the presence of even small amounts of fat before the meringue is baked causes the beaten egg whites to collapse. The principal nutritional components are high-quality protein from the egg whites and simple carbohydrates from the refined sugar.
People who have an egg allergy or egg white intolerance are generally unable to eat meringue.

    the paddle attachment. Mix on medium
    speed until well blended.
  2. Transfer mixture to a 9-by-13-inch rimmed baking sheet. Press batter evenly into baking sheet. Chill in freezer 10 minutes. Bake until golden, 20 to 22 minutes. Let cool completely on a wire rack.
  3. Make filling: Whisk together whole eggs, 1 3/4 cups plus 2 tablespoons granulated sugar, the lemon juice, and 1 tablespoon plus 2 teaspoons lemon zest. Pour over crust. Bake until filling is set, 18 to
    20 minutes. Let cool completely on a wire
    rack. Keep oven at 350.
  4. Make meringue topping: Put egg whites and 1/2 cup granulated sugar in the clean bowl of an electric mixer fitted with the whisk attachment. Beat on medium-high speed until stiff peaks form.
  5. Using an offset spatula or the back of a spoon, spread meringue over filling, swirling to create soft peaks. Bake until meringue begins to brown, 8 to 10 minutes. Let cool completely. Cut into bars. Bars can be refrigerated in an airtight container, up to 1 day.

 

Meringue

Red Grapefruit with Bruleed Meringue

 

Ingredients

  • 2 large egg whites
  • 1/8 teaspoon salt
  • 1/4 cup packed dark-brown sugar
  • 2 red grapefruits, halved crosswise

Directions

  1. Preheat broiler, with rack in lowest position. Put the egg whites and salt in the bowl of an electric mixer fitted with the whisk attachment, and beat on medium speed until frothy, about 30 seconds. Raise speed to high, and add sugar 1 tablespoon at a time, beating until incorporated. Continue to beat until the egg whites hold stiff (but not dry) peaks, about 3 minutes.

  2. Place grapefruit halves, cut sides down, on a large plate; let drain 2 minutes. Invert, and carefully cut between membranes to loosen segments completely. Spoon one-quarter of meringue onto each half, using the spoon to create swirls and peaks. Transfer to a baking pan. Broil, checking frequently, until meringues are browned, about 30 seconds. Serve immediately. Note: The eggs in this dish will not be fully cooked, so it should not be prepared for pregnant women, babies, young children, the elderly, or anyone whose health is compromised.
