Ayam Sioh (Chicken with Tamarind-Coriander) Recipe
Ingredients
240g shallots
3 tbsp coriander seed (you can use coriander powder as well)
1 tsp black peppercorn
4 tbsp sugar
2 tbsp dark soy sauce
4 tsp white vinegar
1 tsp salt
2 tbsp tamarind (assam) paste
1-1.5kg chicken thighs
500ml of water, or enough to come halfway up to the chicken in the pot
2 tbsp plum sauce (or 1-2 preserved sour plum, chopped roughly)
1 tsp white pepper (optional)
Additional salt and sugar, to taste
Steps
1. Peel the shallots, and chop each shallot into 3-4 smaller pieces. Using a food processor, or a mortar and pestle, break up the shallot into a paste. Set aside.
2. In a small saucepan or frying pan set over low heat, gently warm coriander seeds and black peppercorns until fragrant. No oil is required for this. Remove from heat, let cool and then grind finely.
3. In a large bowl, combine the chopped shallots, coriander seeds, black peppercorns, sugar, soy sauce, vinegar, salt and assam paste with chicken. Set aside to marinate for at least 1 hour, or preferably overnight.
4. In a large pot, heat a thin layer of cooking oil over medium-high heat. Scrape the marinade off the chicken pieces (no need to be too thorough on this), then sear the chicken pieces skin-side down, a couple of minutes on each side until browned.
5. Add the rest of the marinade into the pot, and scrape up any fond on the surface of the pot as you do. Add water to the pot until the water level reaches halfway up the chicken. When the water starts to boil, reduce the heat to low just until it is just a low simmer.
6. Continue cooking for about 30 minutes, until the gravy reduced and thickened up. Remove from heat.
7. Add the plum sauce (or plum) and mix well. Add more salt, sugar or white pepper to taste. (If you’ve added too much white pepper and it became too spicy for example, you can balance out the spiciness with sugar, or add a bit of acid from the tamarind or the sour plum.)
8. Serve immediately with rice.
