Yeh it does mash in teh bottom and then vegies in the steam inside the jug or on top in the bigger steamer basket. Cooks the spuds in milk/cream and its delish.
Hubby and I are both chefs and we LOVE the custard - there is a cheats version when you don't have ingredients or are on a diet and theres a really rich real egg/cream one that is amazing. BOTH PERFECT EVERYTIME.
The 2nd one turns into icecream!
