Chicken liver will cost about 55 Baht/500 grams and hearts will cost about 35 Baht/500 grams. For 4 servings, this is about 66 cents per serving.
Variants: 1. This can be prepared with just hearts, just livers, or a mix of both. 2. A blender can be used in place of a mortar and pestle. 3. Add some chopped spring onion, and or cilantro to the pot after adding the coconut milk. 4. Just saute the onion and garlic, that worked well for me.
This recipe for Hachee with Chicken Hearts is from Pisang Susu.
