If you have different vegetables you want to steam, this is no problem, although the cooking times will vary. Potatoes need about 30-35 minutes, asparagus 20 minutes, and broccoli about 15 minutes in the steamer.
To achieve optimal steaming results, first place steamer basket 1 with the vegetables—in this case, the potatoes—on the steamer and start with a 35-minute cooking time. After 15 minutes, place steamer basket 2 on the steamer, this time with the asparagus. After another 5 minutes, place the final steamer basket, 3, on the steamer. After the cooking time is up, all three vegetables are cooked through and ready to eat. Enjoy.
By the way, you can enhance the flavor of all vegetables in the steamer. For example, you can add salt and rosemary to potatoes, a little lemon juice, sugar, and butter to asparagus, and nutmeg to broccoli.
