I will put my 2 cents here as I think everybody has lost sight of what is really Nasi Lemak. Lets preface this by saying I have been eating Nasi Lemak for over 40 years, and I have eaten many if not all the versions. When I was a kid and eating nasi lemak, it was meant as a cheap lunch or breakfast for locals, construction workers and kampung kids like me. I recall that a packet would cost 20 cents, and it used to be as cheap as 10 cents. And it always had the following ingredients, no deviations.
1) The coconut rice (flavoured according to individual maker, but always tasting more or less the same).
2) 1 piece Ikan tamban fish, fried. ( the small fish with very tasty firm flesh). Not Ikan bilis, which was substituted later when Ikan tamban became more expensive and harder to find.
3) 1 sq. shape peice of egg done omelette style. Not fried telor style.
4) 1 piece cucumber, slice.
5) And the most important part, the sambal chilli.
6) All this wrapped in banana leaf.
This simple dish has now developed into the monstrosity that it is and bears no resemblance in original objective, price, or ingredients of the original. because the hawkers cannot make a lot of money from selling such a simple dish as I described, they have to upsell by adding the fried chicken, sometimes beef rendang, or curry chicken, sambal sotong, etc. To me, even the addition of a small quantity of acar already detracts from the original dish that I described above in step 1 thru 6.
The main thing to remember for Nasi Lemak is the sambal chilli. This is the deal breaker here. If the rice is great, and the other ingredients is good, but the chilli is average or below average, it will ruin the whole nasi lemak. Conversely, a good chilli can be so great that u can just eat it with the rice, ignoring all the other ingredients. A good chilli will elevate the whole nasi lemak to great heights that the other ingredients cannot do. Nowadays, they tend to make the chilli too sweet. If you get a good chilli, and its wrapped such a way that the Ikan Tamban, is totally soak and inpregnated with the chilli, so much the better. I find that the Indian muslim version (hard to find in singapore now) holds truest to the original version. I get that a lot of people add fried chicken and all that stuff to the nasi lemak, but than you might as well eat nasi padang if you are going to do that. Having said all this, the best chilli I ever had was made by a chinese hawker. The old style white tshirt with pajama pants guy. And he has passed away long since. Sigh.
