1) Use any combination of almond and coconut milk that you like as long as the total measure is 3 cups. A standard size tin (398 ml) of coconut milk contains almost 2 cups. The more coconut milk you use, the stronger the coconut flavor.
2) This is a very delicately flavored dish, so I did not want to add any extra spices apart from salt and pepper. If you think it needs more lemon, please feel free to add some of the reserved lemon juice to the finished dish.
3) Beans: I tried black beans the first time and chickpeas the second time. Both are good, taste wise, but I preferred the chickpeas because they did not alter the creamy color of the rice.
