The Thai chili paste is sweeter and has lemongrass in it. You may find it in your local Asian store, or even from your local Thai restaurant. To make regular chili paste, sauté oil with yellow onion and garlic until soft, then add chili powder and paprika for color. I would grill the shrimp for extra flavor. This makes a small appetizer for 2 people, or a nice sized one for one.
