1, black rice did not soak direct cooking 30-60 minutes. Ordinary rice cooker steaming needs about 1 hour, pressure cooker needs about 30-45 minutes.

2, black rice itself is larger particles, weak water absorption, need to steam longer than ordinary rice, and the amount of water will be more, so in the absence of soaking, the need to cook is the time needs to be extended; and pressure cooker because of its own sealing and steam is relatively strong, so the time needed will be a little shorter than the ordinary pot.
