Description
A spice blend that combines the acidic, antioxidant-rich sumac with the essential‑oil-laden, antimicrobial za'atar to create a preservative‑rich condiment.
Technical
Sumac’s ellagitannins and organic acids lower pH, inhibiting bacterial growth, while za'atar’s thymol, carvacrol, and rosmarinic acid provide antimicrobial activity. Toasting thyme and oregano at 120–150 °C increases essential oil content by ~30 % without compromising aroma, and blending at a 1:1 ratio balances acidity with herbaceous notes. Adding 5–10 % olive oil forms a stable emulsion that disperses hydrophobic oils, enhancing mouthfeel and extending shelf life.
