Pro Tips

**Chef's Tips & Troubleshooting:**

- Thicken sauces with a cornstarch slurry (cornstarch + cold water) added gradually.

- Cook tomato-based sauces until the oil separates slightly for concentrated flavor.

- Taste and adjust seasoning at each stage, not just at the end.

Cooking Tips

Seafood cooks quickly — remove it from heat the moment it turns opaque and flakes easily with a fork. Overcooking makes it tough and rubbery. Pat shellfish dry before adding to the pan so they sear rather than steam. A hot, quick cook preserves their natural sweetness.

Ingredient Substitutions

Out of cane vinegar? White vinegar, apple cider vinegar, or rice vinegar all work — each brings its own subtle character. Avoid balsamic (too sweet) or distilled white (too harsh). Lemon or calamansi juice can replace vinegar in most marinades and braises. Add a pinch of sugar to balance the acidity. Short on time? A pressure cooker (Instant Pot) can reduce cooking time by roughly half for most braised and stewed Filipino dishes. Reduce liquid slightly since less evaporates.

Storage & Reheating

Store in an airtight container in the refrigerator for up to 3–4 days. The flavors often deepen overnight, making leftovers even more delicious. Seafood dishes are best consumed within 1–2 days. Reheat gently — microwave on low power or warm in a covered skillet over low heat to avoid overcooking. Do not refreeze thawed seafood dishes. Once reheated, consume immediately and do not re-refrigerate. Reheat on the stovetop over medium-low heat, adding a splash of water or broth if the sauce has thickened during storage. Microwave in 30-second bursts, stirring between each.
