To celebrate citrus season here in Israel, Ben Gingi and I created a beautiful, easygoing loaf-cake recipe you’ll make again and again. Sumac makes it extra special, and olive makes it dairy-free. The interior is impossibly moist, and thanks to the semolina the exterior has the most alluring crunch. The hot-pink blood orange syrup we drizzled on top adds another layer of zing. Enjoy!
