Persian Spinach & Yogurt Dip

In Iran, borani is an appetizer made with yogurt and some type of vegetable. I love the simplicity of this dip, which is essentially made with just two main ingredients—spinach and yogurt. Persians love to use spinach in their cuisine, as it originated in Central Asia. The popularity of yogurt in persian cuisine, owes to the fact that for centuries there were abundant herds of sheep and lamb in the area, providing milk. In the days before advanced refrigeration, yogurt kept better. T
