Tamales de Calabaza de Sra. Inés ~ Inés’ Pumpkin Tamales

Cooked tamales

My mom and I always joke around that when a recipe doesn’t work out, it must be a “Mother-in-law Recipe.” What is a mother-in-law recipe? It is a recipe that has been changed ever so slightly so that it won’t come out just right. It is a trick that mother-in-laws play on their daughter-in-laws, so that their sons will always like their mom’s cooking just a little bit better. The mother-in-laws wouldn’t deny their daughter-in-laws of the recipe, but they never tell them what the secret step or ingredient is.

So, that  brings me to this gem of a recipe. This was given to me by my future mother-in-law, Inés. I have adored her pumpkin and shrimp tamales ever since I took my first bite out of one way back in October 2009. Up until that point, I hadn’t given tamales much attention. They always seemed somewhat dry and lacking in flavor. But, these tamales were a game changer for me. They were moist and the flavors were so complex. I couldn’t stop eating them.

Sra. Inés knew how much I loved these tamales. She would make them when I would come to visit Mexico. Even if the pumpkin was out of season, she would search high and low to find one. I remember so well how one time she made these tamales in the middle of April and sent them with Roberto when he went to pick me up at the airport in Mexico City!

I begged Roberto to ask his mom for the recipe. “Please, please, please,” I would plead. “Can you ask your mom to write down her recipe for me?” Roberto was skeptical at first of me wanting to make these tamales in the U.S. First, he argued, we didn’t have access to fresh corn masa. This prompted me to learn all about nixtamal and how to make fresh masa. Once I had conquered that feat, there was the problem of not having access to the right type of pumpkin. So, what did I do? I planted the pumpkin in my garden. Finally, there was the issue of the banana leaves. While I have used frozen leaves to make these thus far, I do have a hardy banana plant growing in my front yard just so I can have access to fresh leaves some day!

Yes, I have gone to extreme measures to make these tamales, but it has been so worth it. Last year when Roberto returned to Poza Rica to visit his family, he did me a great big favor and videotaped his mom making her famous tamales from start to finish. I couldn’t have asked for a better souvenir! I finally had the recipe!

We made these tamales last October and really enjoyed them, but we recently tried our hand at them a second time and had great success!

While this recipe may indeed come from my future mother-in-law, I kind of think she likes me because they came out absolutely perfect! 😉 No “Mother-in-law recipe” here!  And, the best part is that they make Roberto close his eyes and smile from ear to ear because they taste like home. You can’t beat that! So, thank you, Sra. Inés, for trusting me with your famous recipe and for allowing me to make your son smile his beautiful smile right here in Pittsburgh.

Sra. Inés’ Pumpkin Tamales (Makes about 20-25 tamales)

Roasted pumpkin

2.5-3 lb. pumpkin (Use Calabaza de Castilla. It is also called C. moschata, Fairytale Pumpkin, or Musquee de Provence); This will yield about 1-1.5 lbs. of cooked pumpkin

→Cut the pumpkin in half. Clean out any of the seeds and guts using a metal spoon.

→Cut each piece into quarters, then into eighths.

→Fill a steamer with water. A large tamal steamer works best. Place the cut pumpkin in the steamer and put the lid on. Cook for 1 hour.

→Once cooked, remove the pumpkin from the steamer and let cool. When it is cool, use a spoon to remove the pumpkin from its outer shell. Discard the shell.

→Place the pumpkin in a medium-sized bowl, and slightly smash with a spoon. Set aside. (pumpkin)


1 oz. of dried whole shrimp (These can be found at a Mexican grocery store.)

3 oz. of fresh shrimp, boiled

¼ cup water

→In a small skillet, toast the dried shrimp for about 3 minutes until fragrant.

→Place toasted shrimp in a blender. Add ¼ cup of water to the blender so that the shrimp heads/tails mix together easily. Set the pureed mixture to the size (toasted shrimp).

→Remove the shells from the boiled fresh shrimp. Cut into ¼” pieces. Place in a bowl. Set to the side. (fresh shrimp)


4 oz. green pumpkin seeds/pepitas (I bought mine at Trader Joe’s because I was looking for a specific type. TJ’s pumpkin seeds are the closest match I have found.)

1 cup water

→Place pumpkin seeds in a skillet. Toast over medium heat until fragrant, about 3-5 minutes. The seeds will begin to pop when ready.

→Place the toasted seeds in a blender. Add 1 cup of water. Blend for about 1 minute until completely smooth. Place blended mixture to the side. (pipián)

Tomato Mixture

3-4 large Roma tomatoes, quartered

1 small-medium garlic clove

1 slice (about ¼” wide) white onion

2 TBSP vegetable oil (I used avocado oil, but you could use any neutral-flavored oil.)

1 caper, chopped

2-3 seedless green olives, chopped (I used Spanish olives.)

½ cup of fresh cilantro, chopped (I chopped the cilantro and then measured it.)

1 ½ tsp. salt

→Put tomatoes, garlic, and onion in a blender. Blend for about 1-2 minutes until completely smooth.

→Add oil to a medium-sized pot. Heat the oil over medium heat for about 1 minute until it shimmers. Add the blended tomato mixture to the hot oil and begin to cook over medium heat to bring out the flavor. Cook for about 3-5 minutes.

→Add the chopped caper and olives to the tomato mixture. Stir to combine. Then, add the fresh shrimp and toasted shrimp mixture (see above). Stir again to combine.

→Add the chopped cilantro. Mix well. Cook over low heat for about 10 minutes, stirring every so often.

→Then, add the cooked pumpkin (see above). Mix thoroughly and let the mixture cook for an additional 5-10 minutes.

→Add the pipián (see above) and 1 ½ tsp of salt. Mix well and let the mixture cook for an additional minute.


2 lbs. fresh corn masa (see this post for how to make fresh masa) *Make a day in advance

2 cups water

8 oz. pork lard, at room temperature

2 tsp. baking powder

2 tsp. salt

→Put masa in a bowl. Add 2 cups of water and let soak for about 1 hour. Mix with your hand to break up lumps. The mixture should be smooth and resemble atole.

→Place the liquid masa in the bowl of a stand mixer fitted with a whisk attachment. Add the lard, baking powder, and salt. Mix on medium-high speed for about 3 minutes. There should be no lumps and the mixture should still resemble atole.

Forming Tamales

Fresh banana leaves measuring about 12”x12” (This is approximate. The leaves will have a more rectangular shape.

→Place the banana leaf with the hard seam side on your left-hand side.

→Wipe the inside of the leaf clean with a damp rag.

→Pour about 1/3-1/2 cup of masa onto the center of the banana leaf. Add about 2 TBSP of the shrimp/pumpkin mixture to the middle of the masa.

→Fold the banana leaf from the bottom to the top in half. Then fold about an inch from the top towards the bottom. Then, fold all the way down so the top meets the bottom. Fold the left-hand side with the hard seam halfway towards the middle. Lift the tamal up so that the folded hard seam is facing down and the unfolded side is facing straight up. Carefully, fold the top down to meet the other fold in the middle. It should form a square/rectangular packet. Be gentle during this whole process because you don’t want the masa to leak out. Place on a plate and set aside.

→Fill a tamal steamer with water and bring to a boil. Once boiling, turn to medium-low heat. Carefully, place the tamales in the steamer with their folded side facing down. Stack them on top of each other. You should only put about 20 tamales in the steamer at a time.

→Cook on medium-low heat for about 1 hour.

→Turn the heat off, and remove the tamales to a glass tray. Let cool for about 5-10 minutes before enjoying.


  • It is worth trying to find the specific pumpkin mentioned in this recipe. I have yet to try it with a different type of pumpkin. These tamales are seasonal for that reason. We found this pumpkin once at a smaller nursery near our house in October, and once at a Latin market in Boston in September. We also have planted this pumpkin in our garden. If planted in May, it will not be ready until October.
  • You should really attempt to use fresh masa when making these. If you are lucky and have access to fresh masa, this will be easy. If not, you can follow the recipe for fresh masa that is posted on my blog.
  • Good banana leaves are hard to find. They sell the frozen kind at our Mexican grocery store, but sometimes they are cracked and hard to fold. Let them thaw completely, and try to cut them where there are already breaks. We were lucky enough to find packaged fresh leaves at a Latin market in Boston. Sra. Inés says that you could also use corn husks, but they will absorb more of the manteca and will be slightly drier.
  • I suggest making this recipe over a few days so that it is more manageable. I would make the fresh masa first (without the water, lard, baking powder, and salt) and refrigerate it overnight. I would also cook the pumpkin a day in advance. You can even prepare the complete pumpkin/shrimp mixture a day before.
  • The first time you make these, the whole process might seem overwhelming, but the second time I made them, I felt much more comfortable with the each step.
  • My brother is allergic to shrimp, so I have also made a crab version and a chicken version of these. The flavor is totally different, but at least he can enjoy tamales with us.
  • You can reheat any leftover tamales in the microwave! Yay!

    I really enjoyed these and they reheat very nicely. The quality ingredients definitely make a difference in flavor. The Mexican masa smell instantly reminds of Mexico City. Great post!

      Thanks, Chris! It’s nice when you have an audience to cook for 🙂 You know, there are no canned items here. In keeping with the fall-pumpkin, maybe I can post your Sikal Pak recipe soon! Roberto and I loved it. It was fresh yet satisfying.

    • Nicole says:

      Oh wow! I can’t believe you grew these pumpkins, too. They have such a smooth texture once cooked, and I love that they can be used in so many recipes. Yes! It’s kind of strange that the masa is so liquid-like and pourable. That makes them a little harder to fold, but you are right–They come out extremely moist. Good luck making them!
