Dry curries (sabzis) rely on layering spices and caramelizing vegetables for flavor, while wet gravies build flavor through a slow simmering process that melds spices with a liquid base.
The key difference lies in the role of moisture. In a dry curry, or sabzi, the absence of significant liquid forces you to build flavor through different techniques. Here's a breakdown:
Spice Layering: You'll typically bloom spices in oil at the beginning to release their aromas. Then, you'll add ground spices in stages, allowing each layer to cook and meld with the vegetables. This creates depth.
Caramelization: Since there's little liquid, the vegetables have a chance to caramelize, developing sweet and savory notes that are crucial for flavor.
Concentration: The lack of liquid concentrates the flavors of the spices and vegetables, resulting in a bolder taste.
In contrast, wet gravies rely on a liquid base (like tomato, coconut milk, or yogurt) to carry the flavors. The flavor building process involves:
Spice Infusion: Spices are often bloomed in oil, then simmered in the liquid base for an extended period. This allows the spices to infuse the liquid with their flavors.
Melding: The slow simmering process allows the flavors of the spices, vegetables, and liquid base to meld together, creating a harmonious and complex flavor profile.
Emulsification: The liquid base often emulsifies with the fats from the spices and other ingredients, creating a rich and creamy texture that enhances the flavor.
When making a dry curry, don't overcrowd the pan. Overcrowding will steam the vegetables instead of allowing them to caramelize, resulting in a bland and soggy dish. Cook in batches if necessary.
