Steps ~ B 
1 - pour oil into the mixed flour and mix well
2 - add the reserved small pieces of coconut sugar onto a small pot , add 1/3 ginger juice and slimmer on low heat until the sugar dissolved
***keep the heat low heating during the whole process and make sure no over boiling
3 - finally , pour the rest prepared coconut milk into the  ginger coconut sugar syrup ,  turn off the heat and mix well. Keep it slightly warm all the time. 
4 - pour the slightly warm syrup into the flour pot in layers , knead and push the flour until it is smooth, and finally pour the rest syrup…stir well , sieve into another pot before pour onto the oiled container. 
( ***I like the feeling of kneading by hand personally , but use a kitchen hand blender is also a good option too )
5 - slowly pour the batter onto an oiled container , smooth it out and shake it slightly so as to push out the bubbles . 
6 - garnish with a red date and cover loosely with the foil , now ready to steam the cake.
7 - bring water to boil over high heat and place the batter container with tin foil covered in a steamer , steam for 75-85 minutes.
8 - add hot water carefully during the process as needed.  Turn off the heat and check after 75 minutes. Place a bamboo skewer inside the steamed cake , when it comes out clean , it is done.
