Cut the dry chilis in half using scissors or a knife. Combine chilis with the Sichuan peppercorns.
Roughly chop the garlic.
Wash the romaine lettuce with cold water and cut heads into 1.5 inch sections. Discard stem.
Get a wok or large saute pan very hot over high heat and add the oil. I am using a high powered wok burner in these photographs. If you are cooking this on a standard indoor stove, cut the recipe and cook it in two batches. This will allow the pan to stay very hot while stir-frying.
When oil just starts to smoke add the dry chili and peppercorns.
Immediately add the garlic after chili and pepper. Cook for a few seconds.
While the heat is still on high, add the romaine lettuce.
Stir-fry over very high heat for about 20-30 seconds, until romaine gets a little charred and barely starts to wilt.
Add the soy sauce, the pinch of salt and pinch of sugar. Stir fry 10 more seconds over very high heat.
Romaine should be done by now. It should be lightly charred and wilted but still have some texture. Add a touch more salt to taste if necessary.
