This burger uses ground pork seasoned with garlic, brown sugar, soy sauce, cane vinegar, and paprika — the same flavor profile as Filipino longganisa sausage — pressed into patties and grilled until caramelized. The calamansi mayo cuts through the sweetness and keeps things from feeling heavy. It comes together in 30 minutes, and the patties hold up well through the week, which makes it genuinely worth the effort.
Why this recipe works
Two things drive this recipe. First, brown sugar in the mix caramelizes fast on a hot grill, giving you a dark, slightly crisp crust without drying the pork out — that crust is where most of the flavor lives. Second, the vinegar (ideally cane vinegar) does real work: it tenderizes the pork slightly during the 20-minute prep window and keeps the sweetness from tasting flat. Neither of those effects happens if you rush the mix straight onto the grill, so let the seasoned pork rest while you prep everything else.
Mistakes to avoid
- Skipping the fat content check: Lean ground pork (96/4) will produce dry, crumbly patties. Look for 80/20 or ask your butcher for a fattier grind — the fat carries the garlic and sugar flavors through the whole patty.
- Making the patties too thick: Longganisa-style seasoning needs to reach a safe internal temperature of 160°F (71°C). Thick patties take longer, and the sugar crust burns before the center is done. Keep patties around ¾ inch thick and use a thermometer.
- Pressing the patties while they cook: The sugar in the mix means juices carry a lot of flavor. Pressing them out onto the grill means a drier patty and a flare-up from the dripping fat.
- Using regular lemon juice as a calamansi substitute without adjusting: Calamansi is less sharp and slightly floral. If you substitute lemon, use about two-thirds the amount and add a small pinch of sugar to the mayo so it doesn’t taste harsh.
- Storing assembled burgers: The brioche bun goes soggy fast once the mayo hits it. Store patties, buns, and sauce separately and assemble fresh — takes 2 minutes and makes a real difference.
Shopping notes
- Calamansi: Fresh calamansi is sold at most Filipino or Asian grocery stores. Bottled calamansi juice works fine for the mayo — check the label to make sure it has no added sugar, since the patty is already sweet.
- Filipino soy sauce: Brands like Silver Swan or Datu Puti are less salty and slightly sweeter than Japanese soy sauce. If you use a saltier soy sauce, reduce the added salt in the patty mix by half.
- Cane vinegar: Datu Puti cane vinegar is the standard choice and is widely available at Asian grocery stores. In a pinch, white wine vinegar is the closest swap — avoid distilled white vinegar, which is sharper and will overpower the other flavors.
Storage and reheating
Cooked patties keep in an airtight container in the fridge for up to 4 days. For longer storage, freeze them in a single layer on a baking sheet first, then transfer to a zip-lock bag — they’ll keep for up to 2 months. Reheat straight from the fridge in a covered skillet over medium-low heat for about 3 minutes per side, or until the center hits 160°F again. Skip the microwave if you can; it softens the caramelized crust. Raw seasoned patties can also be frozen uncooked — separate them with parchment and cook from frozen, adding 3 to 4 extra minutes per side and confirming 160°F internal before serving.
Filipino Longganisa Burger
Ingredients
For the longganisa burger patties
- 1 lb ground pork Preferably with a mix of fat for juicier patties
- 4 cloves garlic Minced finely
- 2 tbsp brown sugar
- 1 tbsp soy sauce Preferably Filipino soy sauce
- 1 tsp salt
- 1 tsp black pepper Freshly ground for best flavor
- 1 tsp paprika Adds mild smokiness
- 1 tbsp vinegar Preferably cane vinegar for authentic flavor
- 1 tbsp annatto oil Optional, for color and mild earthy flavor
For the calamansi mayo
- ½ cup mayonnaise Preferably Japanese mayo for extra richness
- 2 tsp calamansi juice Freshly squeezed
- ½ tsp honey Balances acidity
For assembly
- 4 medium brioche buns Lightly toasted
- 4 medium lettuce leaves Crisp, fresh lettuce
- 1 medium tomato Sliced
Instructions
- In a mixing bowl, combine the ground pork, minced garlic, brown sugar, soy sauce, salt, black pepper, paprika, vinegar, and annatto oil (if using). Mix until well incorporated, but do not overwork the meat.
- Shape the mixture into 4 evenly sized patties. Place on a plate and let them rest in the refrigerator for at least 15 minutes to allow the flavors to meld.
- While the patties rest, prepare the calamansi mayo by mixing mayonnaise, calamansi juice, and honey in a small bowl. Stir until smooth and well combined.
- Heat a lightly oiled grill or pan over medium-high heat. Cook the longganisa patties for about 4-5 minutes per side, or until they achieve a deep caramelized crust and reach an internal temperature of 160°F (70°C).
- Toast the brioche buns lightly to enhance their flavor and texture.
- Assemble the burgers by spreading a generous amount of calamansi mayo on the bottom bun, followed by the lettuce, tomato slices, and the longganisa patty. Top with the other half of the bun.
- Serve immediately while warm and enjoy!
Notes
- For an extra kick, add pickled red onions or a fried egg.
- You can also substitute calamansi juice with lemon or lime if unavailable.

FAQ
Can I make the patties ahead of time and cook them later in the week?
Yes — raw seasoned patties refrigerate well for up to 2 days before cooking, or freeze for up to 2 months. Shape them, separate with parchment paper, and store covered; the vinegar and soy sauce actually help the flavors develop a little more overnight.
How do I know when the pork patties are fully cooked?
Use an instant-read thermometer and pull them at 160°F (71°C) internal temperature — that’s the USDA safe minimum for ground pork. Don’t judge by color alone; the brown sugar and soy sauce make the patty look dark before it’s cooked through.
Can I use ground chicken or turkey instead of pork?
You can, but cook poultry patties to 165°F (74°C) internal — no exceptions. Ground poultry is also leaner, so add a tablespoon of neutral oil to the mix to prevent the patties from drying out.
What toppings work well if I want to add more than lettuce and tomato?
A fried egg on top channels the classic Filipino longsilog breakfast plate and works well with the sweet-savory patty. Pickled red onions are the other smart addition — their acidity cuts through the richness without competing with the calamansi mayo.
