Marzipan in the context of Krokan

The almond (Prunus amygdalus, syn. Prunus dulcis (Mill.) D.A.Webb, nom. illeg. non Prunus dulcis Rouchy) is a species of tree from the genus Prunus. Along with the peach, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell (endocarp) surrounding the seed.

The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. Shelling almonds refers to removing the shell to reveal the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo. Once almonds are cleaned and processed, they can be stored for around a year if kept refrigerated; at higher temperatures they will become rancid more quickly. Almonds are used in many cuisines, often featuring prominently in desserts, such as marzipan.

Cake is a baker's confectionery usually made from flour, sugar, and other ingredients and is usually baked. In their oldest forms, cakes were modifications of bread, but cakes now cover a wide range of preparations that can be simple or elaborate and which share features with desserts such as pastries, meringues, custards, and pies.

The most common ingredients include flour, sugar, eggs, fat (such as butter, oil, or margarine), a liquid, and a leavening agent, such as baking soda or baking powder. Common additional ingredients include dried, candied, or fresh fruit, nuts, cocoa, and extracts such as vanilla, with numerous substitutions for the primary ingredients. Cakes can also be filled with fruit preserves, nuts, or dessert sauces (like custard, jelly, cooked fruit, whipped cream, or syrups), iced with buttercream or other icings, and decorated with marzipan, piped borders, or candied fruit.

Mahleb or mahlepi is an aromatic spice made from the seeds of a species of cherry, Prunus mahaleb (the Mahaleb or St Lucie cherry). The cherry stones are cracked to extract the seed kernel, which is about 5 mm in diameter, and soft and chewy on extraction. The seed kernel is ground to a powder before use. Its flavour is similar to a combination of bitter almond and cherry, and also similar to marzipan.

Mahleb is used in small quantities to sharpen sweet foods and cakes, and is used in production of tresse cheese.

Almond meal, almond flour or ground almond is made from ground sweet almonds. Almond flour is usually made with blanched almonds (no skin), whereas almond meal can be made with whole or blanched almonds. The consistency is more like corn meal than wheat flour.

It is used in pastry and confectionery – in the manufacture of almond macarons and macaroons and other sweet pastries, in cake and pie filling, such as Austrian Sachertorte – and is one of the two main ingredients of marzipan and almond paste. In France, almond meal is an important ingredient in frangipane, the filling of traditional galette des Rois cake.

Stollen (German: [ˈʃtɔlən] or German: [ʃtɔln] ) is a fruit bread of nuts, spices, and dried or candied fruit, coated with powdered sugar or icing sugar and often containing marzipan. It is a traditional German Christmas bread. During the Christmas season the cake-like loaves are called Weihnachtsstollen (after "Weihnachten", the German word for Christmas) or Christstollen (after Christ). A ring-shaped Stollen made in a Bundt cake or Gugelhupf pan is called a Stollenkranz (stollen wreath).

The Dutch letter (also referred to as banket letter, almond letter, butter letter, and in Dutch as banketstaaf, banketletter, boterletter, and letterbanket) is a type of pastry that is typically prepared using a mixture of flour, eggs and butter or puff pastry as its base and filled with almond paste (or persipan), dusted with sugar and shaped in an "S" or other letter shape. Marzipan, an almond paste prepared with almond meal and honey or sugar, is sometimes used as the filling. The Dutch letter has a porous or airy and flaky texture.

The pastry was originally shaped "into the initial of the family's surname." Nowadays, the most common shape of the food in the United States is as the letter "S". Dutch letters are served as a treat during December, and particularly on Sinterklaasavond on December 5 in the Netherlands, and during some festivals in the United States.
