Daily Morning-Market Procurement Priority
Where to spend your pre-open budget first on japanese ramen simulator ingredients — Priority 1 buys come before anything else.
- P1
Buy split femur (genkotsu) not mixed cuts—marrow yield is 40% higher. Negotiate morning crate price −12% before 06:30.
- P2
Whole bird costs 18% less per kg vs. pre-cut carcass. Buy size 1.2–1.4 kg for best skin-to-meat ratio in japanese ramen simulator umami scoring.
- P3
Rishiri grade costs 2× generic Hidaka but umamiValue 95 vs. 72—use Rishiri for shio/shoyu, Hidaka for miso masking. Reuse spent kombu for tsukudani staff rice (zero waste).
- P4
Thick-shaved (atsukezuri) for dashi, thin (hanakatsuo) for topping only—swapping saves 25% per bowl. Buy hon-karebushi in 1 kg blocks and shave daily vs. pre-flaked bags.
- P5
Dilute 3-year red with 20% white miso for lunch set—cuts cost 18% while keeping umamiValue above 88. Buy 5 kg tub only if miso bowls >35/day.
- P6

- P7
Bulk peeled garlic saves 40 min prep but costs +15%—worth it above 120 bowls/day. Reuse spent garlic solids in staff fried rice (never in customer bowls).
- P8
Buy medium (M) eggs not L—same yolk ratio, ¥3 cheaper/tray. Batch 30 Sunday/Tuesday/Thursday; chashu braise liquid replaces 30% dashi in marinade.
