I love this recipe, fast and really tasty. I made some alterations: used 4 gloves of garlic, 1 teasp of sugar, 1 tablespoon of soy sauce and 1 tablespoon of oyster sauce. First I steamed the fresh beans for 7 minutes and then used only half the sesame oil to saute the garlic. Added the beans, let them cook for 5 minutes then added the sauce and it was done in another 5 minutes. Also having the sauce mixed up and sitting is a good way to prevent ingredients from burning or clumping.
