I used to help my mom make kuih kapit yesterday. The mould being made of metal gets very hot, and you have to work very very quickly to roll or fold the kuih kapit before they cool and become too brittle. The rule is, the thinner and lighter the batter the more skilled you are!
Making kuih kapit requires a certain amount of multi-tasking. The 'chief' cook juggles several tasks at one time – minding the fire, flipping the moulds, mixing and pouring the batter, cooking it to a perfect golden brown colour and then trimming the run-offs. The assistants on the other hand have to quickly fold the kuih kapit into a triangle while it is still hot and pliable and then arranging them into air-tight containers. Althought the latter sounds like a simple task, one must remember that folding of love letters must be done very quickly and neatly, before it hardens and becomes impossible to fold. An experience assistant will also be able to choose the 'nicer side' to face outward so as to make the biscuit look more presentable.
