This
dish is made backwards. You usually start by cooking the meat or seafood, then
the vegetables, and finally the sauce when making a dish. In this case, the
process is reversed; the sauce is made first, followed by the vegetables, and
then the seafood. The dish also has some added heat to it with the addition of
capsicum in red oil or red chili peppers if the former is not available. The
amount to use depends upon how spicy you like your dishes, so the quantity to
use is a personal preference.
Enjoy!
