PreparationFor curry paste: In a mortar, pound chiles and salt with a pestle until pulverized, about 5 minutes. Add ingredients one by one in order listed, fully pulverizing each before adding the next, about 15 minutes total. DO AHEAD: Can be made 1 week ahead; cover and chill. For stew: Combine curry paste, beef, soy sauce, and ground dried chiles in a pot; stir to evenly coat beef. Cook, stirring occasionally, over medium heat for 5 minutes. Add broth and bring to a boil. Cover, reduce heat to medium-low, and simmer, stirring occasionally, until beef is tender but not falling apart, 2-2 1/2 hours. Stir in shallots, carrots, and lime leaves. Simmer until vegetables are just tender, about 10 minutes. If broth is too salty, add water a few tablespoonfuls at a time. Garnish with cilantro and basil.
