Thai Curry Spice Paste

A jar of homemade Thai curry spice paste in the fridge transforms a weeknight scramble into a 20-minute curry. This version stretches dried red chilies and cayenne with whole and ground coriander, caraway, garlic, shallots, and a teaspoon of anchovy paste for the salty-funky umami backbone that fish sauce or shrimp paste would give in Thailand.

Grinding the whole spices first and adding the ground ones afterward is the right order. Toasting and grinding whole spices releases volatile oils that ground spices have already lost, but ground spices distribute through the paste more evenly. You want both.

The final tablespoon of olive oil poured over the top after jarring acts as an oxygen barrier. Air is the enemy of fresh paste flavor, and that thin oil cap keeps the surface from oxidizing for the full two-month fridge life.

Chef Tips

• Toast the whole coriander and caraway in a dry skillet for 1-2 minutes before grinding. The aroma sharpens dramatically once the seeds hit heat.
• Wear gloves when handling the dried chilies. Capsaicin sticks to skin and you’ll regret rubbing your eye six hours later.
• Use a small food processor or mini-prep, not a full-size one. The volume here is too small to grind smoothly in a big bowl.
• Pour the oil cap before sealing every time you use the paste. Fresh oxygen barrier each use, fresh paste for the full two months.

Variations

• Add 1 stalk of fresh lemongrass, bottom 4 inches only, finely chopped, for authentic Thai aroma.
• Stir in 1-2 kaffir lime leaves (slivered) for citrus depth that lemon zest only hints at.
• Use 2 tablespoons in coconut milk with chicken and vegetables for a fast green curry style braise.
