The almond is a deciduous tree with many branches, gray bark and with an elegant white pink bloom before the leaves appear. Introduced in Europe, as in antiquity, from the Middle East and North Africa, its generic name prunus refers to the plum, and the specific dulcis, the taste of its fruit. In the al-Andalus period it became one of the most planted fruit trees due in large part to its edible fruit, the almonds, which presence in the Andalusian cuisine in general and pastries in particular is manifested. Ibn'Awwam, an al-Andalus agronomist wrote: 'There are trees with thick almonds, with sweet little ones, alfónsigo size, and all are planted in the same way. They are planted in the mountains because they love the cold, and in soft earth the tree grows strong and gives more abundant fruit ' Of these trees are said to be the announcement of the good weather and the end of the winter cold. This is also expresses a legend recorded by Henrí Pèrés in 'Splendor of al-Andalus' a collection of Andalusian poetry written in classical Arabic in the eleventh century: 'The white flowers of these beautiful trees, that bloom when the frosts have already disappeared, would replace for al-Rumaykiyya, the beloved wife of the Prince (referring to the ruler of the Alcázar palace, Al-Mutamid), the snowflakes that she had admired a winter in Sevilla '
