In a sauce pan, mix the heavy cream and milk together. Bring it to simmer.

In a large bowl, beat the eggs and sugar together. Then add in (corn starch+water) and vanilla extract. Mix well.

Then gradually add in the cream mixture into the beaten egg, keep stirring.

Sieve the mixture into the baking tray. Put the baking tray in a larger tray, add boiling water into that larger tray. Put the whole thing into preheated oven at 130C, bake for about 55 minutes to 1 hour.

Let it cool completely, then chill in the fridge for at least 6 hours.

Sprinkle some sugar on top, then use a blow torch to caramelise it. Enjoy!
