A ring of coarse sugar glitters only around the edge of a round sabl\u00e9<\/a>. Diamant cookies, sabl\u00e9 diamant<\/em> in French, take their name from the way those crystals resemble diamonds. They are not baked in the shape of a gem. Instead, a single cookie offers both a crumbly interior that falls apart gently and an edge where the sugar grains remain. \u201cSabl\u00e9\u201d refers to the texture, \u201cdiamant\u201d to the finish, and \u201cicebox cookie\u201d to the process of chilling and slicing the dough, so names for different characteristics overlap in one sweet.<\/p>\n

Powdered Sugar Inside, Crystal Sugar Outside<\/h2>\n

In vanilla-flavored versions made with egg yolk, powdered sugar goes into the dough and coarse crystal sugar is rolled onto the outer edge. Although both are sugar, their roles are divided: the sugar in the dough is finely dispersed, while the sugar on the surface is left as visible grains. The egg yolk is mixed into the dough, while the egg white is brushed thinly around the chilled log so that the sugar will stick.<\/p>\n

Mix at Low Speed, Shape into a Log, and Chill<\/h2>\n

To make the dough, soft butter and powdered sugar are combined at low speed to avoid incorporating too much air. The egg yolk is worked in, then the flour is mixed in briefly, and the dough is shaped into an even log and refrigerated. Unlike cakes that rise by holding lots of air bubbles, this dough is made so that thin slices keep their shape and the texture crumbles finely. Chilling the dough until it is firm makes it less likely to lose its shape when cut.<\/p>\n

Baking Without Breaking the Sugar Ring<\/h2>\n

The surface of the chilled log is brushed thinly with egg white, and the log is rolled in sugar. Once the sugar coats it evenly all the way around, it is sliced into rounds, which are laid out cut side up.<\/p>\n

The thickness of each slice also changes how the sugar edge looks. In an example from the baking supply retailer cotta, the same dough was cut 7 millimeters, 1 centimeter and 1.5 centimeters thick and baked for comparison, and the thicker the slice, the more clearly the edge stood out. If more sugar is added after slicing, the grains may cover the edge all the way to the top, so that it looks raised.<\/p>\n

The slices are spaced apart for baking and are done when the edges are lightly colored. They are soft straight out of the oven, so the final texture is checked once they have cooled, and then they are sealed in airtight packaging.<\/p>\n

Dough Variations: Vanilla, Cocoa, Lemon and More<\/h2>\n

Inside the sugar edge, the dough can be made in many ways, with vanilla, cocoa, lemon and other flavorings. The recette (the ingredient proportions and method) from the cooking school L\u2019atelier des Chefs chills a log made with egg yolk, brushes it with egg white and coats it with crystal sugar. In Cerf Dellier\u2019s method, a log combining two colors of dough, lemon and cocoa, is coated in brown sugar. It is not clear who named the cookie or when it first appeared.<\/p>\n

Flour, butter, sugar and similar ingredients form the base, combined with flavorings such as vanilla, cocoa, almonds or walnuts. Some versions add egg yolk and others use no egg at all, and almonds are not essential either. The impression of the first bite also changes depending on whether the flavoring ingredients are worked into the dough or added to the sugar on the outside.<\/p>\n

A Base for Black Sesame Ganache and Fruit Gel<\/h2>\n

Callebaut\u2019s \u201cDiamant Noir\u201d pairs black sesame with the demerara sugar around the edge. The dough uses almond, black cocoa and desiccated coconut, and it is shaped into a log, then frozen and sliced. Whole eggs are used. Compared with vanilla dough made with yolk alone, both the type of flour and the way the egg is blended into the fat are different.<\/p>\n

Along with this baked dough, the creation includes a black sesame ganache made with water and vegetable oil, a passion fruit gel and a sesame tuile. It is an example of a pastry chef using a single sabl\u00e9 as part of a dessert. Keeping the grains around the edge while pairing the sabl\u00e9 with soft layers and tart ingredients can create contrasts in texture and flavor.<\/p>\n

Diamants can be eaten on their own, and they can also serve as a base for desserts layered with tart ingredients or soft components.<\/p>\n
