Thai Red Curry Paste.

Store-bought Thai red curry paste gets the job done, but mortar-pounded paste from scratch has a fragrance and depth that jarred versions can’t touch. This traditional version uses dried red chilies as the base, soaked briefly to soften, then ground with lemongrass, galangal, shallots, garlic, kaffir lime rind, coriander seeds, fennel seeds, and shrimp paste.

Pounding in a mortar rather than using a food processor is the traditional method for good reason. The pestle bruises and crushes the aromatics, releasing essential oils that a blade just chops through. The result is a rougher paste with more aromatic complexity.

Seed the dried chilies before soaking to control the heat level. The seeds and membranes carry most of the capsaicin, so removing them gives you the fruity chili flavor without overwhelming fire.

Pro Tips

• Toast the coriander and fennel seeds in a dry skillet before pounding. Toasting activates their oils and deepens the flavor significantly.
• Pound in order: Start with the hardest ingredients (seeds, dried chilies) and work toward the softer ones (shallots, garlic). This gives everything an even texture.
• Shrimp paste (kapi) smells strong but don’t reduce the amount. It provides the savory backbone the whole paste depends on.
• Freeze in portions: Spoon tablespoon-sized amounts onto a parchment-lined tray, freeze solid, then transfer to a zip-top bag. Keeps for months.

Variations

• Green curry paste: Swap the dried red chilies for fresh green chilies and add Thai basil leaves.
• Milder version: Use fewer chilies and increase the sweet bell pepper to keep the red color with less heat.
