I was looking around for a good Sankaya recipe and ended up with a hybrid of two. Here it is. I have used a 4.5 lbs pumpkin before but I'll stick to a smaller pumpkin. I use packet coconut milk and realise that it comes in 200ml and not 250ml (1 cup). The steamed pumpkin will not be sweet so you may want to put in more sugar to compensate. Cooling time is about 2 - 3 hours. Chill overnight if desired. If you have Pandan essence, use that. Add 1 cup of Ginko Nuts if desired.
