How to Make It
In a large skillet, heat the vegetable oil. Add the garlic, chiles, ginger and onion and cook over moderate heat until softened, about 4 minutes. Add the peanuts and cook until sizzling, about 3 minutes. Add the quinces, lime juice, sugar and salt. Cover and simmer, stirring a few times, until the quince is barely tender, about 3 minutes. Let cool slightly. Stir in the mint and cilantro and serve.
Quinces are available at most supermarkets from October through December.
