You can also get from Tracy Juice Culture, i seen it stated on their flyer.
Kelly, i stated 8-10mins in the recipe, you can do it at 5-7mins, it depends how thick you want the kaya. Upon cooling, it will thicken a bit.
Sugar, you can chose to carmelise the sugar first if desired. Brown sugar (orange colour) or black sugar (brown in colour) or palm sugar can be used. Adjust the sugar, because the sweetness vary for different type of pumpkin.
Want Ya Kun type of kaya, don't forget the ingredient - pandan. Heard that pandan power is available at the supermarket, yet to chk it out.
Taste - it is almost there, the main ingredient that determine the kaya is coconut milk not the egg.
