Japanese Ramen Simulator Broth Calculator (Site Model)

Q: Are these numbers from the game?

No. Umami, Brix, Emulsion(T), and ROI come from our broth-model.ts fan estimate — not Wild Dog’s internal math. Use the in-game purchase screen and customer reviews.

Q: Did the Day 1 patch change broth display?

v0.1.50.17746 (2026-10-09) fixed purchase-UI umami/aroma display bugs. This tool stays labeled as a site model. See /changelog.

Q: How do I share a recipe?

Copy share link adds ?v=1&s=tr:bg:ba:88 (stock:tare:noodle:temp). Canonical URLs omit query strings.

Q: How does the reverse solver work?

It exhausts 3×3×3×13 = 351 combos and returns the Top 5 matches for your targets (umami, Brix, cost, etc.), or the closest fits if none qualify.

Unofficial broth bench for Early Access (v0.1.50.17746): estimate USM, Brix, emulsion and margin. Shareable URLs and a reverse solver — a site model, not in-game data.

How are these numbers calculated? SITE MODEL

Formulas below match broth-model.ts — not Wild Dog’s in-game math.

Glu = stock.glu + tare.glu; Ino = stock.ino + tare.ino
stock/tare tables in broth-model.ts (site assumption)
USM = 1 + 0.15×min(Glu,Ino)/100; if Glu≥90 and Ino≥90 → USM=1.35
Umami Synergy Multiplier (wiki model)
Emulsion(T): 86–92°C→1; <85°C→0.62; ≥95°C→0.88; else mid bands 0.78/0.94; ×(1+stock.emulsionStock)
Piecewise holding temperature (wiki model)
raw = (Glu×Ino)^0.72 × USM × Emulsion(T); display Umami = round(raw×0.118) + signatureBoost; if T<80°C: Umami−8, Aroma−12
Scaled 0–100 for UI; not in-game umami meter
Brix ≈ stock.brix + tare.brix + 4.2 (1 decimal)
Relative sweetness/solid estimate (wiki model)
Aroma = stock.aroma + tare.aroma + noodleDelta[barikata|futsu|yawarakame]
Deltas: 2/0/-3
Suggested price = round(cost×3.2/10)×10; ROI% = ((price−cost)/cost)×100
Margin heuristic for planning only

Planning band: ~60–70% stock, 15–20% tare, 10–15% emulsified fat. USM = 1.0 + 0.15×min(Glu,Ino)/100; both Glu and Ino above 90 → cap 1.35 (site assumption).
