This is a great condiment to have in your arsenal of culinary skills. Bascially, it is a bright red, hot sauce made from chilies, garlic, vinegar, sugar, and salt.
The sauce can be used in dishes that you want to have some spice to it. Also, its great for dumplings as a dipping sauce with soy suace, sugar, and vingear to mix.
Sometimes, I combine it with mayo for a sandwich.
