Ramly burger sellers in Singapore cook with no heart and soul.

They precook the patties and reheat them later when the
customers place their order... in doing so, they save time, but
much of the freshness is lost!
This is heresy, I say..... this is blasphemy! 
Actually hor, in the past I can still get pretty good Ramly burgers
from the Pasar Malams here
These days they all sux!!!!!!
I should try making at home since we do buy the patties from
NTUC which is similar to what they use!!
I use them in sandwiches. Haha
