This is another well-known Indonesian (or Asian) cake. Creamy vanilla rum custard with light choux pastry shell, lovely combination!
Some tips and tricks that I can share:
- Make sure to pre-heat the oven to the required temperature before baking
- Do not open your oven door when baking the choux pastry shells, otherwise they will not puff up
- You’ll notice tiny bubbles around the choux pastry shells when they are baking, do not take out the pastry shells until almost all or all of those tiny bubbles are gone
- Do not over mix the flour and egg (maximum three minutes of mixing), they just need to be incorporated well, otherwise the batter will be too runny and cannot hold its shape. I believe this doesn’t affect the taste at all, only appearance.
