Pho is comfort food Asian style. Light broth with zesty flavors that won't weigh you down. To slice pork paper thin chill it in the freezer for 30 minutes and use very sharp knife. The pork cooks in the hot liquid and is very tender.
In a bowl combine the noodles with hot water to cover and let soak for 10 minutes. Drain and set aside.
In a small frying pan combine the star anise, coriander seeds, cinnamon and cloves. Toast the spices over medium heat stirring frequently until fragrant. 2 to 3 minutes.
In a large saucepan combine the broth, ginger, garlic, fish sauce, sugar and toasted spices. (If you are using dried chilies place them in broth also). Bring to a boil and reduce to a simmer and simmer for 30 minutes. Strain soup through a fine mesh strainer and return to the pan. Add noodles and bring back to a boil and cook 5 more minutes.
Remove from heat and add the pork with remaining ingredients. The pork will cook in the hot liquid immediately. Ready to serve.
