Why It Works

  • Using lard and butter in the dough produces flavorful and tender conchas.  
  • Kneading the dough in a stand mixer quickly develops a strong gluten network.  
  • A cold fermentation builds flavor and makes the dough easy to work with. 
  • Scoring the concha crust with a butter knife gives the conchas their distinctive seashell appearance.

With its soft, spongy dough, sweet, crunchy crust, and buttery flavor, nothing beats the taste of a freshly-baked concha. Sold at Mexican panaderias, the concha (which means "shell" in Spanish) is one of the most recognizable pan dulces, or sweet breads. However, finding a great concha can be quite the feat, especially if you don't have a good panaderia nearby. 

After I left the restaurant industry to give birth to my son, I started a virtual bakery called Mexipino, combining nostalgic flavors and traditional desserts from my husband’s Mexican culture and my own Filipino background. I wanted to build a connection between our two heritages through food. Because of this, I began to learn more, digging deeper into Mexican breads, and eventually developed my own recipe for traditional conchas, which I’m sharing here. At Mexipino, I like to take it a step further and stuff the Mexican concha like a Filipino ensaymada, a soft sweet bread traditionally coated with butter, sugar, and grated cheese, with ube halaya (a Filipino purple yam jam) or black bean paste. 

Making the Concha Dough

A great concha hinges on the type of fat and flour used in the dough. Traditionally, lard, or manteca, provides flavor and richness, but nowadays, many panaderias and bakers use margarine or shortening for its stability, longer shelf life, and as a way to cut costs. I prefer a combination of processed lard, the hydrogenated semi-solid white version normally found in most grocery stores, and butter. Lard tenderizes the dough by coating and weakening the gluten strands, resulting in a softer texture. Lard alone can create a flatter bread, so I add butter too, which releases steam during the bake to create air pockets. In addition, the butter adds a richer flavor.

For the flour, I compared conchas baked with bread flour and all-purpose flour and I found that bread flour, which I call for here, gives the conchas a firm, springy, chewy texture that mirrored the ones I ate in Mexico City. All-purpose flour, on the other hand, made much lighter conchas. If you only have all-purpose flour on hand, you can substitute for the bread flour, just note that the texture won't be as substantial.

Using a stand mixer helps achieve a brioche-like texture by slowly incorporating the fat into the dough and developing a strong gluten structure. While I provide an estimated kneading time below, it’s best to perform the windowpane test to check if the gluten is sufficiently developed: Once a smooth, shiny dough has formed that pulls away from the sides of the bowl, use your hands to remove a piece of dough and stretch it gently taut into a translucent sheet. Once the gluten is properly developed, I start the bulk fermentation at room temperature and perform a set of stretches and folds to add more strength to the dough. I then let the dough proof in the refrigerator for 12 hours, which results in a more flavorful dough and makes it much easier to work with. Afterwards, I portion the dough and shape each into a smooth ball before moving onto the crust.

Preparing the Concha Crust

If you’ve ever eaten or seen a concha, you've likely taken note of the crackly crust on top. Traditionally, the crust is made with lard, powdered sugar, and all-purpose flour, and is flavored with chocolate or vanilla (which is often dyed pink for a pop of color). The stand mixer makes quick work of bringing the crust together. Plus, with my recipe, you’ll be able to enjoy both popular flavors because I split the crust in half and flavor each half separately. Once the flavored crusts are made, I portion and chill both halves to help with assembly.

When it’s time to shape the crust, you have two options: You can flatten it with a rolling pin or press it in a tortilla press. Once the crust is flat, I place it on top of a dough ball, making sure to tuck in any overhang. To score the top, it’s traditional to use a concha cutter to engrave the signature seashell pattern, but if you don’t have one, I found that using a butter knife works just as well. Just make sure to score only the crust and take care to not pierce the dough underneath.

If I’m planning on making conchas on a certain day or for a special occasion, I make the dough the day before, let it rise in the refrigerator overnight, then bake it the next day in time for an afternoon snack. Meanwhile, the crust can be made ahead of time or while the dough is proofing. Conchas are best enjoyed the day they’re baked, either for breakfast with a steaming mug of café de olla (Mexican coffee prepared in a clay pot with cinnamon), or eaten as a snack with a tall glass of cold milk. Personally, I like eating conchas all by themselves but sometimes I’ll indulge and split one in half, stuff it with ube halaya or ube ice cream, and enjoy it for dessert.

Directions

  1. To make the concha crust: In the bowl of a stand mixer fitted with the paddle attachment, beat lard on medium speed until smooth and creamy, about 30 seconds. Using a flexible spatula, scrape down bowl and paddle attachment. Add powdered sugar and all-purpose flour and beat on a medium-low speed until no dry flour remains and a smooth paste forms, about 4 minutes. Scrape down bowl and paddle, add vanilla, and beat on medium-low speed until vanilla is fully incorporated, about 30 seconds.

  4. Divide vanilla-flavored paste into 8 equal portions (about 30g each), forming each into a smooth ball, and transfer to a parchment-lined rimmed baking sheet. Repeat with chocolate-flavored paste. Cover tightly with plastic wrap and refrigerate for at least 1 hour and up to 3 days.

  5. To make the concha dough: In a large bowl, whisk together yeast, bread flour, powdered milk, sugar, and salt until thoroughly combined, about 30 seconds. Set aside.

  6. In the bowl of a stand mixer fitted with the dough hook attachment, add eggs and water and mix on low speed until combined, about 1 minute. Add flour mixture, increase speed to medium-low, and mix until flour is completely absorbed and a rough dough forms, about 2 minutes. Increase speed to medium and mix until a cohesive dough forms (it will remain attached to bottom of bowl and be sticky), about 5 minutes.

  7. Reduce speed to medium-low. With the mixer running, alternate adding butter and lard a few cubes or tablespoons at a time, pausing to scrape down bowl and hook as needed, until thoroughly incorporated, about 10 minutes. Increase speed to medium and mix until dough has become smooth and shiny and pulls away from the sides to form around the dough hook (the dough should not be sticky), 8 to 10 minutes. To test the dough, tear off a small piece and stretch gently in all directions; when the dough is ready, it can be pulled into a thin, translucent sheet.

  8. Using a bowl scraper, transfer dough to a lightly-oiled large bowl, cover tightly with plastic wrap, and let rest at room temperature for 15 minutes. With two clean wet hands, slide hands under left and right side of dough and gently pick it up from the middle, letting the ends fold under itself. Cover with plastic and let dough rest for another 15 minutes. Rotate bowl 90 degrees and repeat folding process. Cover tightly with plastic wrap and refrigerate overnight or up to 12 hours.

  9. Line three rimmed baking sheets with parchment paper. Turn dough onto a clean, floured surface, but do not deflate. Divide into 16 equal portions (80g each). Working with one portion at a time, pull edges of the dough towards the center, pinching ends together, to create a tight ball. Place the seam side down on the counter, then cup dough beneath your palm and work it in quick circular motions to form a smooth ball. Transfer to a prepared baking sheet. Repeat with remaining portions of dough, for a total of 5 to 6 balls per baking sheet. Cover dough balls loosely with plastic wrap to prevent the dough from drying out while preparing the crust.

  10. To prepare the concha crust by hand: Fold a 12- by 16-inch sheet of parchment paper in half crosswise, open the folded paper like a book, and grease the inside with cooking spray. Remove one portion of the concha crust from the refrigerator, place portion in the center of one half of the prepared parchment paper and cover with the other half. Using a rolling pin, roll out into a 4-inch circle about 1/8-inch thick. Carefully peel away top half of parchment paper and transfer crust to the palm of your hand, peeling away the rest of the paper. Top a dough ball with the crust, tucking sides underneath, then press down slightly to flatten the crust and ensure it adheres to the dough. Repeat with remaining concha crust and dough, re-greasing parchment paper after each use.

  11. To prepare the concha crust in a tortilla press: Cut the sides of a 6 1/2- by 5 7/8-inch plastic sandwich bag so that it opens like a book, place the open bag in the tortilla press, and grease the inside with cooking spray. Remove one portion of the concha crust from the refrigerator, place portion in the center of one half of the prepared bag, cover with the other half, and press into a 4-inch circle about 1/8-inch thick. Carefully peel away top half of bag and transfer crust to the palm of your hand, peeling away the rest of the bag. Top a dough ball with the crust, tucking sides underneath, then press down slightly to flatten the crust and ensure it adheres to the dough. Repeat with remaining concha crust and dough, re-greasing the plastic bag after each use.

  12. Working with one concha at a time, hold a butter knife at a 30-degree angle and position the knife at one end, close to the middle, then make a curved line across the top to the other end (be sure to score only the crust and not the dough underneath). Repeat scoring above and below the first curved line, for a total of 6 to 7 lines per concha (the lines should resemble a seashell in appearance; see note). Repeat with remaining conchas.

  14. Thirty minutes before baking, adjust oven racks so that one is in upper-middle position, the other is in lower-middle position, and preheat oven to 350°F (177°C). Bake two trays of conchas, switching racks and rotating trays front to back after 10 minutes, until puffed and golden brown, about 20 minutes total. As soon as two trays are fully baked, remove from oven and set third tray in oven to bake.

Special Equipment

Stand mixer, rimmed baking sheets, wire rack, rolling pin or tortilla press

Notes

Processed lard is hydrogenated to make the fat shelf-stable and does not impart a pork flavor. If preferred, the lard in the concha crust can be replaced with an equal amount of unsalted butter by weight. 

If desired, you can purchase a plastic or stainless steel concha cutter to achieve the seashell pattern on the crust online. For this recipe, you’ll need one that’s 3.25 inches in diameter. 

Make-Ahead and Storage

Conchas can be stored in an airtight container at room temperature for up to 3 days. To freeze conchas, wrap individual conchas tightly in two layers of plastic wrap, transfer to a zipper-lock bag, and freeze for up to 1 month. To defrost, leave out individually wrapped conchas at room temperature until softened, 1 to 2 hours.
