Tostones de Pata: Twice-Fried Pork Trotters with Piquillo Garlic Mayo
Tender, gelatin-rich pork trotters are slow-braised until falling off the bone, then breaded and twice-fried to achieve a shattering, golden crust. This dish is crowned with a vibrant, spicy aioli made from roasted Piquillo peppers and garlic, merging the rustic heartiness of a stew with the textural excitement of a tapas appetizer.
A little context
While 'tostones' typically refers to fried plantains in Latin America, this adaptation applies the double-fry technique to pork trotters (pata), a staple in traditional Spanish cuisine known for their collagen-rich texture. The dish draws inspiration from the Basque Country's love for rich, garlic-heavy sauces and the widespread use of Piquillo peppers from Navarra. In Spain, trotters (pata) are often slow-cooked for hours to break down connective tissue, then often served as a hearty tapa or a main course alongside crusty bread to soak up the juices.
Method
- 01
Braise the trotters
Place trotters, onion, garlic, bay leaves, peppercorns, and salt in a Dutch oven. Cover with stock. Bring to a boil, skim foam, then reduce heat to low. Cover and simmer gently for 2.5 to 3 hours until the meat is extremely tender and easily pulls away from the bone.
- 02
Cool and separate
Remove trotters from the broth (reserve broth for soup) and let them cool completely on a wire rack. Once cool, remove the meat from the bones. Cut the meat into bite-sized chunks or small medallions, discarding any large bones but keeping the skin and connective tissue attached for texture.
- 03
Dredge the meat
Pat the meat pieces thoroughly dry with paper towels. Dredge them lightly in the flour, shaking off any excess. This thin coating is crucial for the first fry to create a seal.
- 04
First fry (Blanching)
Heat oil in a deep pot to 150°C (300°F). Fry the trotter pieces in batches for 4-5 minutes until they are set and lightly golden but not crispy. Remove and place on a wire rack to cool completely. This step cooks the interior without burning the exterior.
- 05
Make the Piquillo Mayo
While the meat cools, combine egg yolk, minced garlic, sherry vinegar, paprika, and cayenne in a blender. Blend for 10 seconds, then slowly stream in the 150 ml of oil while the motor runs to form a thick emulsion. Add the drained Piquillo peppers and blend until smooth and vibrant red. Taste and adjust salt.
- 06
Second fry (Crisping)
Increase oil temperature to 190°C (375°F). Return the cooled, par-fried trotter pieces to the hot oil. Fry for 2-3 minutes, turning once, until deeply golden brown and shattering crispy.
- 07
Drain and serve
Remove the tostones immediately and drain on a wire rack (not paper towels, to keep them crisp). Sprinkle lightly with sea salt. Serve hot, topped generously with the Piquillo Garlic Mayo.
Pro tips
- ✦Ensure the trotters are completely cool before the second fry; this temperature shock creates the signature 'tostón' crunch.
- ✦Do not skip the skim step when starting the braise; removing the foam ensures a clean, clear broth if you save it for soup.
- ✦Use a kitchen thermometer for the oil; if it's too cool, the meat will absorb oil, and if too hot, the flour will burn before the meat heats through.
- ✦Make the mayo ahead of time; the flavors of the garlic and peppers meld beautifully after 30 minutes in the fridge.
- ✦If the trotters are too fatty, trim excess skin before the second fry, but keep the gelatinous parts for texture.

Substitutions
- Piquillo peppers → roasted red bell peppers + 1/4 tsp smoked paprika (less sweet and smoky, but acceptable)
- Sherry vinegar → red wine vinegar + 1/2 tsp sugar (mimics the slight sweetness of sherry)
- All-purpose flour → rice flour or cornstarch (creates an even crispier, lighter crust)
Storage
Store cooled, fried trotters in an airtight container in the fridge for up to 2 days (do not refrigerate before frying). Re-crisp in an air fryer or oven at 200°C (400°F) for 5 minutes. The mayo keeps separately for 3 days.
What to serve with it
- Crusty Spanish bread (pan de pueblo) to scoop up the mayo
- Crisp green salad with sherry vinaigrette to cut the richness
- Rioja Crianza or a bold Tempranillo red wine
- Cold Spanish lager or a dry Cava
FAQ
Can I use pork belly instead of trotters?+
Yes, but reduce the braising time to 45-60 minutes. You will lose the unique gelatinous texture that makes trotters special, as belly is leaner in connective tissue.
Is the mayo safe to eat raw?+
Traditional Spanish aioli uses raw eggs. For safety, use pasteurized eggs or eggs from a trusted source. If concerned, you can poach the egg yolk gently for 1 minute before blending.
Can I make this in an Instant Pot?+
Yes. Cook on High Pressure for 45 minutes with natural release. The meat will be tender, but you must still perform the double-fry step to achieve the 'tostón' texture.
