Pastırma (Kayseri pastırması, Erzurum pastırması)pastırma
Large cuts of beef are slit, packed with nitrite curing salt, washed, pressed flat and air-dried, then coated in çemen, a paste of fenugreek, garlic, red pepper and cumin, and dried again. It is mainly a salt-and-drying cure; staphylococci and lactic bacteria grow in the meat but there is no deliberate sour stage. Made in 10 steps over 3.4 months – 6.7 months. The longest step, keep cold, takes 3–6 months (TÜRKPATENT 2002) and runs at 0–4 °C (TÜRKPATENT 2002). Salt is 6–8 % (TÜRKPATENT 2002). Coagulase-negative staphylococci (Staphylococcus xylosus, S. saprophyticus, S. equorum, S. vitulinus), the main microbes in pastırma does most of the fermenting.
Amounts from a sourceAmounts are for one tonne of meat in the Kayseri Pastırması geographical indication (registration no. 36, amended 2022).
1 tonne
Beef from the back, leg and shoulder of healthy male cattle aged 2–5 years and at least 250 kg[kayseri]
60–80 kg
Nitrite curing salt (5 g nitrite per kg salt), known as "karıncabaş"[kayseri]
15 % of the meat weight
Wet çemen paste · 45 % fenugreek–vetch–wheat flour (30 % fenugreek seed flour, 30 % vetch, 40 % wheat), 5 % spice (1.5 % sweet and 1.5 % hot red pepper, 2 % cumin), 5 % garlic, 45 % water; ice instead of water in summer to prevent souring[kayseri]

What makes this one different
Pastırma is slit and packed with curing salt, pressed flat twice and finished in a thick çemen paste of fenugreek, garlic, red pepper and cumin. It is cured and dried rather than soured.
Erzurum pastırmasıRib-eye, sirloin and leg of grass-fed Erzurum cattle; per 100 kg of product 115–125 kg meat, 9.5–12.5 kg salt, 7–12.5 kg çemen and 50 mg/kg sodium nitrite. Two salting rounds (24–48 h, then 12–24 h), çemen-drying 8 days at 20 ± 1 °C and 70 ± 2 % humidity; pH 4.5–5.8, salt at most 7 % of dry matter, in three grades with çemen at most 6, 8 or 10 %.
Safety
Nitrite curing salt is used to hold back Clostridium botulinum and other pathogens. The Kayseri rule keeps finished pastırma at 0–4 °C for 3–4 months. Staphylococcus aureus, including MRSA with enterotoxin genes, was found in 9 % of samples along the production chain.
Hazards the sources name: Staphylococcus aureus, including MRSA with enterotoxin genes (9 % of 400 production-chain samples); Clostridium botulinum (controlled by nitrite curing salt).
Kayseri pastırması was registered as a Turkish geographical indication (no. 36) in 2002. It appears in Evliya Çelebi's Seyahatname and other historical documents.
