The spinach is cooked so long and so dark that first-time diners often assume the stew is built on meat drippings rather than greens.
Spinach is cooked down for hours with garlic, white beans and beef until it turns a deep, near-black color and develops a rich, earthy sweetness. It's one of the signature dishes of Djerba's historic Jewish community.
Why it's made this way: Pkaila belongs to the t'fina family of slow-cooked Sabbath dishes and is traditionally eaten on Rosh Hashanah eve; on Djerba, where Jewish and Muslim communities have long shared food traditions, it's cooked and eaten by everyone, not just Jewish households.
