Decide your texture need: whole specks for pan sauces vs. smooth tang for cream/butter sauces.
Choose a “pepper base” (black or pink peppercorns) and a “tang source” (brine-like vinegar, capers, or rehydrated green peppercorns).
Use the listed ratio, then taste: add tang in small increments (vinegar/capers/brine) to match the original bite.
For sauce use, simmer gently 30–60 seconds after adding tang so the flavor rounds, not sharpens.
If using chopped capers or crushed peppercorns, adjust salt only after tasting—briny items change overall seasoning.
