Ratio Consistency
Also known as charcutier's percentage
The fourth Pillar. The mathematics of curing are not approximate. Salt, cure and sugar are weighed as percentages of the meat, so a result can be trusted and repeated.
Ratio Consistency is the Pillar of measurement. Curing runs on percentages: salt at 2.2 to 2.5% of the meat, nitrite at 156 ppm, sugar dosed to reach a target pH. These are not seasonings added to taste; they are the numbers that make a cure both safe and repeatable, and they are weighed to the meat, never judged by eye.
For whole muscle the equilibrium, or EQ, method is the clearest expression of this. Rather than burying the meat in excess salt and judging the timing, the exact weight of salt and cure is calculated to the meat and left to distribute evenly, so the final concentration is known in advance and cannot overshoot. It is safer, more even, and repeatable batch after batch.
Precision matters most with nitrite. Too little loses the protection against Clostridium botulinum; too much is harmful. A small, weighed, correct amount is the entire point, which is why the curing salts are diluted, dyed and calculated to the gram.
