What You Need to Know
At 180–200 °C, oil acts as a non‑polar solvent, extracting hydrophobic essential oils such as eugenol from cloves and cumin. The heat also initiates Maillard‑like reactions between amino acids in spices and reducing sugars, forming new flavor compounds that deepen aroma and taste.
