• 1 cup hulled pumpkin seeds
• 4 tablespoons lard or neutral oil, like corn or grapeseed
• 2 cups chicken stock, preferably homemade (page 160), or water
• 3 or 4 ancho chiles, to taste
• 2 garlic cloves, peeled
• Salt and freshly ground black pepper to taste
• Fresh lime juice to taste

1. If the pumpkin seeds you have are already toasted, proceed to step 2.
2. Otherwise, heat 3 tablespoons of the lard in a heavy skillet over medium-high heat.
3. A minute later, add the pumpkin seeds and cook, shaking and stirring the pan constantly for a minute or two, until the seeds start to puff.
4. (Take care not to overcook the seeds, which will make the sauce bitter; and be prepared for flying seeds popping out of the pan.)
5. Remove the toasted seeds with a slotted spoon and cool.
6. (Discard any blackened seeds.)
7. Meanwhile, warm the stock and soak the chiles in it.
8. When they have softened, after 10 to 15 minutes, remove their stems and seeds; reserve the soaking liquid.
9. Put the seeds in a food processor and process until pasty, stopping the machine and scraping down the sides if necessary.
10. Add the garlic, chiles, and as much of the soaking liquid as you need to process until quite smooth.
11. Turn the heat under the pan back to medium and add the remaining lard or oil.
12. Reheat the sauce with enough liquid to thin to a pleasing consistency, stirring occasionally, until it just boils and thickens slightly.
13. Remove from the heat.
14. Taste and add salt and pepper as needed, then stir in the lime juice; serve hot or at room temperature.
15. (This keeps well, covered and refrigerated, for up to 3 days; bring back to room temperature or reheat before serving and always add the lime juice at the last minute.)
16. In step 2, add 2 tomatoes (preferably peeled and seeded) and 2 to 4 garlic cloves, peeled, to the mix; you will need less of the reserved liquid.
17. Omit the lard and toast the pumpkin seeds as you would sesame seeds (page 596).
18. Omit the ancho chiles and puree the toasted seeds with chile powder to taste (about 1 tablespoon), at least 1/4 cup chicken stock, preferably homemade (page 160), or water, and salt and pepper to taste.
19. Reheat and add the lime juice.
