For Xmas dinner 2007, I made nut roast with roast vegetables including two members of the Basellaceae family (known as the Madeira vine family). It contains the following genus: Anredera, Basella, Ullucus and plantlist.org also assigns Tournonia hookeriana (previously Basella) to the same family.
I also cooked some Basella alba (malabar or ceylon spinach) greens to serve with the dinner.
Is this the only time all 3 main members of the Basellaceae have been served together? ;)
