• 2 teaspoons coriander seeds
• 2 teaspoons cumin seeds
• 1/3 cup roasted salted cashews
• 1 1/2 teaspoons turmeric
• 1 tablespoon finely grated fresh ginger (preferably using a Microplane)
• 1 tablespoon finely grated fresh garlic (preferably using a Microplane)
• 1 medium tomato, halved crosswise
• 1/4 cup vegetable oil
• 6 to 8 whole dried arbol chiles, stemmed
• 1 medium onion, halved and thinly sliced
• 2 small red sweet peppers, cored and seeded, then halved; or 1/2 larger red bell pepper, cut into 1/2-in. slices
• 2 small yellow sweet peppers, cored and seeded, then halved; or 1/2 larger yellow bell pepper, cut into 1/2-in. slices
• 2 small orange sweet peppers, cored and seeded, then halved; or 1/2 larger orange bell pepper, cut into 1/2-in. slices
• About 1/2 tsp. salt
• 1 can (13.5 oz.) coconut milk
• 1 tablespoon tamarind concentrate
• 1 tablespoon packed light brown sugar
• 1 1/2 pounds albacore tuna loin, cut into 3/4-in.-thick medallions
• 1 1/2 to 2 tbsp. lime juice
• 1 cup loosely packed mixed fresh herb leaves, such as basil, cilantro, and mint, torn if large

1. Put coriander and cumin in a spice grinder or clean coffee grinder and grind until fine. Transfer to a bowl. Put cashews in grinder and grind into a paste. Add to bowl and stir in turmeric, ginger, and garlic.
2. Grate tomato on the large holes of a box grater into another bowl, discarding skin. Set aside.
3. Heat oil in a large, straight-sided skillet over medium heat. Crack half the chiles open and add to pan along with onion. Cook, stirring, until onion softens, 2 to 3 minutes. Add peppers and continue cooking until vegetables begin to soften, 3 to 4 minutes. Add spice paste and 1/2 tsp. salt and cook, stirring often, until paste begins to fry, about 2 minutes. Add grated tomato, coconut milk, tamarind, brown sugar, and 3 tbsp. water; add 1 to 2 tbsp. more water if it seems thick. Reduce heat to medium-low and simmer 5 minutes, uncovered.
4. Tuck tuna pieces into sauce and gently simmer, covered, turning fish once, until almost cooked through, about 3 minutes. Stir in lime juice and season to taste with salt. Transfer to shallow bowls and top with herbs.
5. *Find tamarind concentrate at Indian markets, or add a little extra lime juice instead.
