made orh lua with sweet potato flour 1 egg & 8 large oysters on 12.1.2019. ^^
(for the starch, 1 tbsp sweet potato flour 3 tbsp water, 1 egg)
i added 3 tbsp water to 1 tbsp sweet potato flour. added 2tsp fisg sauce and some white pepper. mixed thorough and added to non-stick pan 1 tbsp oil on high fire. let the starchy flour form a crispy layer.
then added 1 egg & spread it. added 8 large oysters. covered to cook the oysters while further browning the flour.
this time hawker standard, crispy egg & flour…
i cooked that again for my sis & bil a few days later, just as good! very good wokhae!
can improve a bit more..maybe add 2tbsp sweet potato flour and less ratio of water 9say 4-5 tbsp) for a thicken starchy base…
anyway overall oysters plump and tasty, egg and flour crisp and yet starchy…quite good but can still improve.
