As soon as I unboxed it, I was surprised at how much capacity it has, I would say about three times more than the pots we were using. This is great and allows for a greater cooking consistency across all the vegetables because you can spread them out more. I would have no fear doing a Christmas meal for 10 people and feel confident I would have enough capacity for the veg. Considering how much you can fit into this steamer; it really does reduce to a small size when packed away. It can take plenty of water, so I don’t need to top it up mid-cook, it heats up quickly, and the timer is very handy because I can set a timer for my oven and a timer for my veg, then have a glass of wine and relax. Well worth the money, and you can’t go wrong with Tefal.
