I purchased this 3-4 years ago for pasta use (original price: 14,300 yen), but there was also one that said it was for asparagus. Since my family has downsized, I haven't been using it recently, so I'm putting it up for sale. Although I haven't used it many times, there is some wear on the inside because I boil things in salted water. * Compatible heat sources: Compatible with all heat sources including IH and gas. (Microwaves are not included as a heat source) * Dishwasher safe From the official page: The TWIN® Specials series is designed for those who want to easily enjoy special cooking. It's a new style of cookware series from Zwilling that expands the range of cooking with a variety of variations and an easy-to-use design. How to use the Pasta & Vegetable Cooker: Place vegetables or pasta in the stainless steel insert and boil them as is. Once cooked, lift out the stainless steel insert. (※When using the insert to cook pasta, please use pasta of 1.8mm or more.) For asparagus, etc., hook the insert's hook onto the pot, boil the hard parts of the asparagus first, and then put the insert completely into the pot to boil the whole thing to an even firmness.
