About Mang Tomas Style Sauce
Also called: homemade Mang Tomas sauce, lechon sauce, Filipino liver sauce, sarsa
This is a homemade version of Mang Tomas, the bottled Filipino lechon sauce: a sweet, tangy, peppery gravy made from pork liver, vinegar, sugar and breadcrumbs. Mang Tomas is a brand name; the generic sauce is called lechon sauce or sarsa. Pork liver spread (sold in cans in Filipino and Asian groceries) does the work of the traditional mashed roast liver. The breadcrumbs thicken the sauce, the cane vinegar keeps it sharp, and the brown sugar balances the liver. Black pepper is what makes it taste like the bottled version.
It is served as a dipping sauce for lechon (whole roast pig), lechon kawali, fried pork belly and roast chicken. The finished sauce is thick, smooth and brown, with a pourable texture similar to gravy. It thickens further as it cools, so loosen it with a little water if needed. The flavor should be sweet first, then sour, then peppery.
Serving and keeping
Serve at room temperature or warm alongside roast or fried pork. Keeps 1 week in a sealed jar in the fridge; loosen with a splash of water when reheating.
Variations
Spicy
Add 1 or 2 minced chilies (siling labuyo) with the garlic and onion.
From fresh liver
Broil or pan-fry 4 oz pork or chicken liver, mash it smooth, and use it in place of the liver spread.
Smoother
Blend the finished sauce for a pourable, bottled-style texture.
If it goes wrong
Sauce is lumpy
Whisk the liver spread into the onions in step 3 until smooth before adding the liquid, and add the breadcrumbs while stirring.
Too thick
Whisk in water a tablespoon at a time. It thickens further as it cools.
Too thin
Simmer a few more minutes, stirring, or add another tablespoon of breadcrumbs.
Tastes flat or too sweet
Add more cane vinegar and black pepper a little at a time.
Substitutions
- cane vinegar: white vinegar or apple cider vinegar. White vinegar is sharper; use slightly less.
- pork liver spread: liver pate. A softer flavor; add a little extra pepper.
- fine breadcrumbs: crushed saltine crackers. Thickens the same way; reduce the salt.
