Achieving a perfectly balanced Thai curry paste involves carefully balancing hot chilies, aromatic roots like galangal and ginger, fragrant herbs like lemongrass and kaffir lime leaves, and savory elements like shrimp paste. Adjusting these ingredients to your taste is key.
Making a balanced Thai curry paste from scratch is an art, but here's a step-by-step guide to help you master it:
Gather Your Ingredients: The core ingredients for green curry paste typically include green chilies (Thai chilies are common), galangal, lemongrass, kaffir lime leaves, coriander root, cumin seeds, white peppercorns, garlic, shallots, and shrimp paste. Red curry paste uses dried red chilies instead of green.
Prepare the Chilies: For red curry paste, rehydrate the dried chilies by soaking them in warm water for about 30 minutes until softened. Remove the seeds if you prefer a milder paste. For green curry paste, simply remove the stems from the fresh green chilies.
Pound or Blend: Traditionally, Thai curry paste is made using a mortar and pestle. Start by pounding the tougher ingredients like lemongrass, galangal, and kaffir lime leaves into a paste. Then, add the chilies, followed by the garlic, shallots, coriander root, and spices. Finally, incorporate the shrimp paste. If using a food processor, pulse the ingredients in batches, starting with the tougher ones, until a smooth paste forms. You may need to add a little water to help the blending process.
Taste and Adjust: This is the most crucial step. Taste the paste and adjust the ingredients to your liking. If it's too spicy, add more galangal or lemongrass to balance the heat. If it lacks depth, add more shrimp paste (but be careful, a little goes a long way!). If it's too sour, add a touch of sugar. If it lacks freshness, add more kaffir lime zest or coriander root.
Storage: Store the finished curry paste in an airtight container in the refrigerator for up to a week, or freeze it in small portions for longer storage.
When using a food processor, avoid over-processing the paste, as this can generate heat and alter the flavor. Pulse in short bursts and scrape down the sides of the bowl frequently.
