Causa Nikkei applies Japanese ingredient vocabulary (sushi-grade salmon, yuzu, sesame, ikura, wasabi) to the Peruvian causa (PRU-03) structure — producing a preparation that represents the most accomplished culinary fusion tradition documented in Provenance. The architecture remains Peruvian (yellow potato, ají amarillo, lime); the flavour components are Japanese; the result has a logic that neither tradition alone produces.
- **The causa layer:** Identical technique to PRU-03, but ají amarillo reduced slightly — the Japanese flavour components are more delicate and should not be overwhelmed - **The filling:** Raw salmon (sashimi-grade), dressed with yuzu juice, sesame oil, a small amount of soy sauce — the Japanese vinegared rice's character applied to the causa filling context - **The garnish:** Ikura (salmon roe), thin-sliced cucumber, wasabi (fresh-grated if available), a single leaf of shiso - **The logic:** Ají amarillo's fruity heat + yuzu's complex citrus + sesame's fat = a flavour architecture where each element reinforces the others. The ají-yuzu-sesame combination is one of the most compelling Nikkei discoveries — the Capsicum baccatum's fruity compounds share aromatic territory with yuzu's citrus terpenes, producing a perceived synergy
