🌶️ Why Spice Matters for Grilled Vegetables

When vegetables hit the grill, something magical happens. Maillard reactions create those gorgeous char marks, but without proper seasoning, they’re just a plate of brown stuff with good lighting. The spice equation works differently on grilled vegetables compared to meat:
- Veggies have less surface fat, so spices don't adhere as easily
- Cell structure changes during cooking, affecting flavor absorption
- Water content impacts how spices penetrate during grilling
- Caramelization creates new chemical pathways for flavor interaction
This isn't just cooking — it's
vegetable alchemy. The right spice combination can enhance sweetness, balance bitterness, and amplify natural flavors in ways you never imagined possible.
