Many cuisines, particularly Mediterranean, Middle Eastern, and Southeast Asian, use spinach because it is affordable and easy to prepare. The plant is native to ancient Persia (now Iran and surrounding areas) and migrated to India, where it was called “Persian vegetable,” then made its way to China through Nepal. The Saracens introduced the plant to Italy through Sicily. Spinach became a staple food during Lent, and during the reign of the French queen Catherine de’ Medici, born in Florence, she had the plant used in all recipes, so much so that spinach became known as “Florentine“.
Spinach comes in many varieties and can be found in three groups that include Savoy, semi-Savoy e flat leaf. The Savoy varieties are curly, wrinkled, and have a spongy texture. The flat leaf spinach varieties are smooth and have a larger leaf than the Savoy variety. The semi-Savoy varieties have characteristics of Savoy to a lesser extent and are larger and flatter.
Spinach is a versatile food that can be used in a myriad of recipes. The leaves should be washed thoroughly as they tend to collect sand and dirt. When cooking spinach, use minimal heat, minimal cooking time, and limited contact with liquids. It is suggested to boil the leaves to release the acid content, making them sweeter to the taste. Spinach is a great ingredient for lasagna, salads, side dishes, and main courses. Some serving suggestions are poached eggs on spinach, warm spinach salad with tuna, and sautéed spinach with sweet potatoes. According to the United States Department of Agriculture, a 1/2 cup serving of spinach contains 28.1 micrograms of vitamin C, 34% of the daily recommended amount.
