Question: Can I buy another steamer basket and stack one on the other one?
Document: Just to confirm another review I read this steamer set fits perfectly into a Calphalon pressure cooker. In fact, it looks like it was made for it, there is very little space around the outside for food to fall through. I think a second basket would stack on top of the first one inside this pressure cooker so I may order a second one and give it a try.
This is so much better than the rack that came with my Cuisinart. I also bought the stainless steel pot insert and they make a great combination. The rack sits up so much higher than the orignial one and it's larger too, so a whole chicken fits better. I'm looking forward to trying the steamer basket on St. Patrick's Day for my potatoes and cabbage!
This works great with my Nesco pressure cooker. The steamer basket lets me cook vegetables without worrying that they'll be soggy. The rack is exactly like the one that came with my cooker except that the legs are longer - - works well if I'm cooking more in the bottom of the pot.
Pressure steaming potatoes in a basket is far superior to pressure cooking them submerged in liquid!If you have the same pressure cooker as I do and are concerned about damaging the nonstick surface I suggest that you buy a6-quart Pressure Cooker 18/10 Stainless Steel Cooking Pot. It teams up very well with this rack and steamer basket set.
I wanted a steamer basket for my Instant Pot and this fits perfectly into the 6-quart Instant Pot. Happy camper!
This is a great rack and steamer basket set. Fits most all of the 6 quart units. Their Stainless pot is great too. Enjoy.
It works ok but the folding wire handles are fiddly - I think you could do better with another choice.
The Ravck and Pot fits perfectly in my Instant Pot. I like it. (I'm surprised the Instant Pot didn't come with one....)
One more thing...the pamphlet that comes with it is next to useless...what little info it contains is very poorly written and disjointed. Make the investment in one of Bob Warden's books (or others) or go online to familiarize yourself with pressure cooking.
That is unless you overfill the basket (which I have done)!
Answer: There is just enough room in terms of height for a second steamer basket, but if you got an identical basket without the rack, I don't think it would "stack."  The diameter of the bottom of the basket is smaller than the top, so it would not sit on top of the first basket like you want.  It would likely nest inside the first basket without another rack or some sort of spacer for the second basket to sit on.
