Heat up a dry pan over moderate heat and toast the sesame
seeds for about 3-4 minutes, shaking the pan gently until golden brown.
Remove immediately from the pan to prevent burning. Trim the ends of the
spinach, chop the leaves and wash to remove all grit. Combine the
scallions, garlic, cayenne pepper and pork. Mix well.
Heat the oils using a heavy-based frying pan. Stir fry
the pork quickly over very high heat until golden. Break the frying into
3 batches. Remove the meat and set aside. Add sugar, spinach, and soy
sauce. Toss lightly. Cover and cook for 2 minutes or until the spinach
is just soft. Return the pork to the pan, add the sesame seeds, toss
well and serve immediately.
