When Tomassian started, za’atar was an obscure import. Today, it sits on Costco shelves. Labneh was a niche yogurt; now it’s a breakfast staple. He didn’t single-handedly create this shift, but he provided the scaffolding—the reliable, high-quality ingredients that allowed chefs and home cooks to experiment with confidence.
