Melt butter in large saucepan over medium heat. Add pasta and cook, stirring occasionally, until browned, about 3 minutes. Add ginger and rice and cook, stirring occasionally, until edges of rice begin to turn translucent, about 3 minutes. Add broth, salt, and cumin and bring to boil. Reduce heat to low, cover, and cook until all liquid is absorbed, about 10 minutes. Off heat, remove lid, fold dish towel in half, and place dish towel over saucepan; replace lid. Let stand for 10 minutes. Fluff rice with fork; stir in figs, walnuts, cilantro, and lemon juice; and serve.
