This is not just efficient but also saves a lot of time. I do this with rice/pasta or anything that requires boiling. Also, using a pressure cooker can save a lot of time/energy with foods like legumes/meats etc.

+1 for pressure cooker. I use mine twice a week or so. For just about anything since there are so many recipes online. And less clean up!
