Protocol · storage · shipping · questions

Almost everything that goes wrong with a rebloomed bowl is water temperature or water volume. The protocol below fixes both; the rest of this page covers everything else.

The 90-second protocol

Four moves. The third one is the only one people get wrong.

  1. Boil

    Bring water to a full rolling boil — 100 °C at sea level. Electric kettle, stove, camp stove: the source doesn't matter, the temperature does.

  2. Pour to the line

    Open the pouch, leave the puck in the bowl, pour boiling water to the embossed fill line (400–430 ml, printed per bowl). Cover with the lid.

  3. Wait 90 seconds

    Set a timer. Not 60, not 180. At altitude above 2,000 m, add 20–30 seconds.

  4. Stir from the bottom

    One full stir from the base of the bowl to re-suspend the tare, and eat. The egg is at the bottom; rescue it first.

Run the clock

The crystal fills as the bowl blooms. Sixty seconds leaves a dry noodle core; three minutes softens it past the point of return.

Ninety seconds

1:30

Lid on. Do not stir until the timer ends.

A bowl mid-bloom: broth surfacing through the noodle lattice as steam lifts off the surface.

Second 40 · broth re-emulsifying

If the broth looks thin

Two causes, both fixable. Water below 95 °C will not re-suspend the fat, so it stays in visible flakes — reheat and it will not recover, so start with a hard rolling boil. Too much water thins the tare: every bowl is seasoned for its exact volume, and the fill line inside the bowl is the volume we tested.

Questions we actually get

Ten, in the order they arrive

Why exactly 90 seconds?Rehydration

The noodle lattice rehydrates from the outside in at a known rate: at 100 °C, a 1.3 mm noodle reaches full core hydration between 80 and 95 seconds. Shorter leaves a dry core; past 3 minutes the noodle keeps absorbing and softens. 90 seconds is the tested center. Set a timer — the difference is real.

Does the water really need to be boiling?Rehydration

Yes — 100 °C at sea level, a full rolling boil. At 95 °C, add 15 seconds. Above 2,000 m altitude water boils cooler, so add 20–30 seconds and stir at the end. Warm tap water will not rebuild the broth emulsion; the fat stays in flakes instead of re-suspending.

How much water?Rehydration

It's printed on every lid — 400–430 ml depending on the bowl. Use a marked vessel the first few times. Too much water thins the tare; the bowls are seasoned for their exact volume. The inner wall of the shipping bowl has a fill line.

Two years without a freezer — really?Storage

Really. Sublimation removes 98.6% of water content, and we seal each bowl with an oxygen absorber in a nitrogen-flushed pouch at under 2% residual O₂. No water activity plus no oxygen means nothing to spoil. Store below 27 °C, out of sunlight. The freezer adds nothing.

The pouch puffed up in shipping. Is it safe?Storage

A slightly domed pouch at altitude (air freight, mountain delivery) is pressure differential, not spoilage — our pouches leave the line under mild vacuum. If a pouch is torn, or the puck inside has gone soft or sticky, don't eat it; email support with the lot code and we'll replace it.

Do you ship cold?Shipping

No — that's the point. Bowls ship ambient in a paperboard case, USPS or UPS Ground, anywhere in the US. Orders over $60 ship free. No ice packs, no dry ice, no doorstep race. Current dispatch time is 1–2 business days from the Georgetown facility.

International?Shipping

Canada now (5–9 business days, duties included at checkout). EU and Japan are in customs review — join the waitlist from the cart page and we'll email when your country opens. Freeze-dried meat products cross borders slowly; we'd rather do it correctly than quickly.

Is anything fried, powdered, or 'flavor packet'?Product

No. Every bowl is cooked complete — broth, noodle, toppings — exactly as we'd serve it, then frozen at −41 °C and sublimated whole for 22 hours at 0.0004 atm. There is no seasoning sachet because the seasoning is already in the bowl. Cup noodles are flash-fried and rebuilt from parts; this is the finished dish, paused.

Allergens?Product

Every bowl contains wheat (noodle) and soy (tare). Eggs, pork, chicken, fish (dashi), sesame, peanut, and dairy vary by bowl — the full matrix is on each product page and printed on the lid. Kinoko Shio is our only fully plant-based bowl. All bowls are produced on shared equipment.

How does The Standing Order work?Subscription

Pick bowls, pick an interval — every 2, 4, or 6 weeks — and we ship automatically at 10% off. Skip, swap bowls, or cancel from any shipment email; changes lock 48 hours before dispatch. No commitment beyond the shipment already boxed.
