After a lot of testing, I've found that the best way to store it is to treat it just like a bouquet of flowers. Snap or cut off the dry ends (although, to be honest, I’ve been known to skip this step when I’m in a hurry). Then, stand your asparagus up in a wide-mouthed jar or drinking glass that’s filled with enough water to submerge the bottoms of all your asparagus spears. If you want to go a step further, you can tightly cover it in plastic wrap (don’t smash the delicate tips!). Store it in the fridge until you’re ready to cook it. I don’t remember where I first learned this trick, but it’s the same tactic used by experts at Food Network and The Kitchn.
