A frankfurter is a protein net holding fat hostage. The word botulism means sausage. The pink, the salt and the cold are the line between dinner and that name.
What you’ll learn
- The frankfurter is not ground meatSee an emulsion sausage as a protein-fat-water batter whose coat is extracted myosin, not as coarsely ground meat in a tube.Frankfurters, wieners, bologna and mortadella are fine batters. Salt-soluble proteins coat fat; heat sets the gel. The FAO prefers the word batter to true emulsion.
- Ice is an ingredientPut chopping order and cutter temperature in the right places: lean and salt first, fat late, finish under the FAO ceiling.Extract myosin from cold lean before fat arrives. Ice keeps pork fat from smearing. Past about 18°C the coat fails and the cooked sausage weeps.
- A terrine is a different buildingSeparate terrine, country pâté, pâté en croûte and liver mousse from emulsion sausage, and name their binders.A terrine is a forcemeat loaf cooked in a water bath. Liver can emulsify. Aspic is a different glue. None of this is a frankfurter batter.
- Botulus means sausageFollow the documented line from Wildbad and Kerner to van Ermengem's rod, and treat a casing as an anaerobic room.Botulism is named from botulus, sausage. Kerner described the poison; van Ermengem isolated the anaerobe. Smoke alone is not the fix.
- The safety line is a stackStack salt, nitrite limits, nitric oxide, pH 5.3 with degree-hours, and a 160°F cook as separate hurdles.Comminuted nitrite tops out at 156 ppm. Fermented sausage must hit pH 5.3 on a clock. Fresh sausage still needs 160°F. Cold finishes the stack.
- Uncured is a labelRead 'uncured' as a legal word, treat a home terrine as cooked leftover, and leave dry fermentation to people with a scale and a culture.Indirect celery-powder cures still make nitrite. Summer sausage is a process. A house terrine, a pâté en croûte and rillettes are perishable unless the rest of the stack is real.
Questions this course answers
What actually holds the fat in an emulsion-type sausage?
The FAO describes a batter in which extracted meat proteins bind water and keep fat droplets dispersed, then set on heating. Smoke and casings do not do that job.
Put the bowl-cutter steps in the order that actually extracts protein and coats fat
The FAO's two-phase chop extracts protein from lean first, then incorporates fat under a temperature ceiling, then stuffs and heats.
Match each product to the architecture it actually is
These are cousins, not synonyms. The binder, the grind and the heat path all change.
Where does the word botulism come from?
Botulus is Latin for sausage. The illness was named for the food that kept killing people in nineteenth-century Germany.
What is the United States maximum ingoing sodium nitrite, in ppm, for a comminuted sausage such as a frankfurter?
The USDA handbook, as restated by Sebranek and Bacus, limits comminuted products to 156 ppm sodium nitrite on the green weight of the meat. Dry-cured products may go to 625. Bacon is 120.
In the AMI GMP for fermented sausage, why must the batter reach pH 5.3 on a degree-hour clock?
S. aureus is not strongly inhibited by nitrite. A rapid drop to pH 5.3 is the GMP's main brake on its growth and toxin during fermentation.
