To Prep
Add coconut milk, eggs, sugar and salt in a mixing bowl and whip until well combined and all sugar has dissolved.
Sift all-purpose flour and rice flour into the mixture. Whisk until the mixture has the consistency of pancake batter (Add a little water if too thick).
To Cook
Heat up oil in a wok on medium heat.
Place brass moulds in the hot oil, about 2-3 mins. (The moulds have to be hot enough for batter to cling on them).
Dip hot mould into batter for 10 secs. Make sure batter coats only the bottom and sides of mould, never over the top.
Slowly lift it up and dip mould back in hot oil. Shake to release from mould and fry until golden brown on both sides.
Remove from hot oil, and let it cool over paper towel.
Repeat until all batter is used up. Store in air-tight containers.
