Ok... wasting no time in tightening my belt, I hereby started with cooking my own kaya. For 15 eggs, 2 packets of coconut milk and 750g of sugar, plus 3 hours worth of gas and time, I managed to produce 3 tubs of kaya, which should last me a long time. Tasted really good and it's so simple even my 17 yr old can cook it...well he's doing most of the stirring for this batch, albeit reluctantly...
This is how it looks about 1 hour down the cooking time
After 3 hours... waiting for it to be cooled before transferring into tubs
See the texture? Very smooth!
