I figured I'd ask here first, as I'd expect you guys to know the answer. Way back in 2010 or 2009 my wife and I bought a 25 pound bag of Jasmine Rice at Costco. We store the rice in a cool dark place, but the bag is still open and not sealed (we just roll the top down). We transfer the rice into smaller jars to keep in the kitchen and cook with in the rice cooker. The last few batches of rice we've cooked has come out mushy. So much so, that you almost end up with a lump of undefinable mush, instead of a mass of sticky rice grains. I checked the bag last night and it said "best before April 12, 2011" and we are way past that date. Has the rice gone bad? Any advice on how to store it? This isn't a prepper question, more along the lines of I'd rather buy it in bulk. Thanks.
