Tagine cooking time -- clay pot vs pressure cooker, by protein
Tagines are not all the same time. A whole lamb shank takes 3.5 hours in a clay pot, 45 minutes in a pressure cooker. A chicken kefta is 75 minutes in clay, 25 in pressure. The protein and the cooking vessel drive the answer.
The tool
What this solves
Tagine timing is the most common failure mode of a tagine. Too short and the meat is chewy; too long and the vegetables are mush. The 'low and slow' intuition is right but the actual time varies 2-3x by protein. This tool gives the right number, the doneness cue, and the altitude compensation if you're cooking in Imlil.
How to read the result
The total time is cook time, not prep. Add 25% for prep (chopping, browning) and 15% for resting before serving.
Altitude adds 2-3% per 1000m above 1500m. Imlil (1740m) adds ~5%; Toubkal refuge (3200m) adds ~22%.
Doneness cues are how you verify the time. Trust the cue, not the clock.
Limitations
Times are based on a 3L tagine on a gas burner at moderate heat. Larger tagines (5L+) cook more slowly. Cooking on charcoal (the original method) is different -- slower but more flavour. The altitude math is a linear approximation; real altitude effect depends on humidity and atmospheric pressure.
FAQ
Can I use a metal tagine?
No. Metal tagines exist but lose the moisture cycling that makes the dish work. Use the clay pot with a diffuser if on gas.
Do I need to soak the tagine first?
New tagines need 24h soak + oil + bake at 100--C for 1h to seal. Old tagines are already sealed. Don't soak seasoned tagines in water; the seasoning will wash out.
Why does my tagine stick?
Too high heat. Clay tagines are designed for very low gas or charcoal. Use a diffuser on a gas burner.
