Cheese from the Mediterranean, Iberia, the Pyrenees and the Balkans
Hard pressed ewe cheese family (Manchego and Pecorino Romano as templates)Pecorino Romano
Whole ewe milk is set with rennet, often lamb rennet paste, and the fine curd is stirred and warmed, from about 28–40 °C for Manchego to 45–48 °C for Pecorino Romano. The curd is pressed in patterned moulds, salted in brine or dry, and aged from a month to two years. Made in 6 steps over 30 days – 3.3 months. The longest step, salt, takes 3 h – 2.3 months (Consejo Regulador DOP Queso Manchego 2025). Salt is up to 2.3 % (Consejo Regulador DOP Queso Manchego 2025). Streptococcus thermophilus and Lactobacillus delbrueckii subsp. lactis and Enterococcus faecium do most of the fermenting.
No fixed amounts recordedFamily template, so the ingredients are the ones hard ewe cheeses share. The specifications read give no amounts.

What makes this one different
The milk is whole ewe milk, rich in fat and protein, and many members use lamb or kid rennet paste, which breaks down fat for a sharp taste. Pecorino Romano is cooked hotter and salted for weeks; Manchego is set cooler and brined for hours.
Hard ewe cheeses are pressed and aged, and the UK NHS lists hard cheeses as safe in pregnancy, unpasteurised or not. Manchego PDO sets a limit of 100 cfu/g for coagulase-positive staphylococci in the cheese.
Hazards the sources name: Coagulase-positive staphylococci from milk or handling; Manchego PDO allows at most 100 cfu/g; Clostridium spores in ewe milk (mainly C. sporogenes), which cause late blowing in Manchego.
