From Step-by-Step Thai cooking. This is a really tasty red curry, with the sauce made form scratch. The green beans seems superfluous, so I marked them optional.
Drain chilies and limes leaves. Slit open chilies and scrape out seeds.
Toast coriander, caraway seeds and shrimp paste in a dry wok until aromatic. Place in food processor and add lemon grass, garlic, onion and ginger. Process until well combined
Add soaked chilies and lime leaves and food process until a smooth paste is formed.
Heat oil in a wok. Add paste and cook for 3 min. Stir in coconut milk and cook for about 25 minutes (until oil floats to surface)
Slice meat into strips 3/4 inches wide. Add meat and green beans to the mixture in the wok.
Simmer 15 minutes. Add fish sauce and stir.
