Choose the closest substitute by flavor goal: smoky depth (chipotle), tomatoy heat (chili paste + roasted pepper), or fermented chili warmth (gochujang).
Start with the table ratio, then adjust: if your dish needs more “tomato body,” add a spoon of tomato paste; if it tastes flat, add a few drops of lemon or vinegar.
For thickness-sensitive uses (dressings, marinades, spreads), blend or whisk until smooth; for sautéing, stir into warm oil for 30–60 seconds to bloom spices.
Taste before serving: add salt carefully (adobo and some chili pastes are salty) and control sweetness by using less gochujang or mixing in more acid.
If baking or roasting, apply early so flavors distribute; for finishing sauces, use near the end so heat stays bright.
