a dry cast-iron skillet over medium-high heat. When the skillet
is hot, add the pumpkin seeds, cumin seeds, black pepper and
dried oregano. Heat the spices until they just begin to smoke
and the seeds pop, about 5 minutes. Do not let the seeds turn
brown.
Remove the spice mixture to a bowl to cool. When the spices
are room temperature, transfer to a coffee bean grinder
and grind the spices to a powder.
In a blender or food processor, add the tomatillos, Serrano
chiles, garlic, romaine, cinnamon, cilantro, radish tops,
onion, salt, sugar and olive oil. Process the mixture until
pureed.
Re-heat the cast-iron skillet over medium-high heat. Add
the tomatillo mixture and stir. Stir in the chicken stock.
Reduce the heat to medium-low and simmer the sauce for 25
minutes. Return the heat to medium-high and add the reserved
spice powder. Continue to cook the sauce another 5 minutes.
Return the sauce to the blender and puree a second time.
Add the apple cider vinegar to the sauce and puree again.
Keep the sauce ready to add to the prawns.
Re-heat the cast iron skillet again to medium-high heat.
Add the olive oil and then the prawns. Sauté the
prawns just until they turn pink, about 1 minute. Turn the
prawns over and cook on the second side, another 1 minute.
Pour 1 ½ cups of the pumpkin seed mole into the
skillet. Continue to cook until the prawns are done and
the sauce is heated through, about 6-8 minutes.
The pumpkin seed mole makes a wonderful salad dressing.
Toss the mole with some romaine, salt, pepper, olive oil,
lemon juice and cojaita or peppered feta cheese.
