The Big Kumara

This big kumara (aka 'sweet potato') was one of several dug up from a garden in Tauranga which uses liquid vermicast last weekend. We can't be sure how much credit to give the worm juice but this giant of the Convolvulaceae family has some impressive statistics:

• Circumference 45cm
• Length 27cm
• Width 15cm
• Weight 2.4kg
  

By the way, a recent carbon-dating study indicates that of the ancient middens found so far which contain varieties of kumara, those from Papua New Guinea appear to be significantly older than those from Central or South America - no real surprise there

Anybody got a good recipe?
