Stainless Steel Upright Asparagus Steamer Kettle 2.8L 5 "Fabulous Invention!" Mrs MacFarlane 09 December 2017 I love my asparagus kettle! No more soggy asparagus, simple to use, asparagus cooked in no time. Just cover bottom of asparagus with an inch or two of water and the asparagus simply steams. Also useful for corn and for blanching vegetables using the basket.
