Cold-smoked rainbow trout
Cold-smoked rainbow trout is salt, drying and smoke under 25 degrees. The fish becomes sliceable, not flaky like hot-smoked. It is a different job from smoked rainbow trout. Parasites do not die in cold smoke – freeze.
Fillet first: fillet rainbow trout.
How to do it
Cure
Salt and sugar pull liquid and set the flavour. 12–18 hours is enough for a fillet. Longer and you get ham.
Pellicle
Dry it cold on a rack. The tacky surface is what the smoke sticks to. Skip the step and the smoke comes out patchy.
Smoke
Cold. Not a grill with the lid on at 80 degrees – then you have hot-smoked. Alder and beech are the usual woods. Several hours; your smoker sets the clock.
Freeze
2–3 days. Before the cure or after the smoke. No shortcut.
Serving
Thin slices, horseradish, dill, lemon, an open sandwich. Not a hot sauce.
Tips
If you have no cold smoke: cure it gravad. Same fish, another page. Arctic char is often cold-smoked – see smoked Arctic char for the hot-smoked track.
FAQ
What is the difference from hot-smoked?
Hot-smoked is cooked in heat and becomes like poached fish with smoke. Cold-smoked is raw in texture, like gravad, with smoke. See <a href="/tillaga/rokt-regnbage">smoked rainbow trout</a> for the hot track.
Do I have to freeze it?
Yes. Cold-smoked fish is never heated through. Freeze 2–3 days before or after, the same as <a href="/tillaga/gravad-regnbage">gravad</a>.
Can I cold-smoke without a smoker?
No. Without smoke it is gravad fish. Make <a href="/tillaga/gravad-regnbage">gravad rainbow trout</a> instead.
