Find your cooking goal: you need either (a) liquor-like anise depth, or (b) a non-alcoholic anise flavor boost.
Choose the closest match from the table: use 1:1 for other anise liqueurs/pastis, or use the lower ratios for extract/spices.
Add early if you’re simmering (so the anise disperses), or add near the end for a brighter top note.
Taste after the first simmer/bloom; if it’s too sweet, cut with a splash of lemon juice or a little water/broth.
If the aroma is too weak, add a small increment (not a full re-measure) and let it cook 2–3 minutes more before deciding.
