Technically how expert is that? Bread mold edition

A recent news article caught TPP's eye because it showed moldy (mouldy for some of you) bread. Then an expert, a senior technical information specialist for the United States Department of Agriculture, proceeded to give you advice about cutting mold off your bread or any other soft food. First of all the mold is obviously Penicillium, and it is not particularly harmful especially in such small amounts.  When you are eating blue cheeses you are eating species of Penicillium that were grown on bread before inoculating the milk curds with moldy bread crumbs.  A senior technical information specialist should know this, don't you think?  They go on about the problem with soft foods. 
"With soft food, it's very easy for the roots [of the mold], or the tentacles, or whatever creepy word you want to use....Basically, the mold spore's roots go much farther into bread than our eyes can see."  The roots, tentacles, or whatever creepy word you want to use?  How about filament or mycelium, one of the right words for the body of a fungus?Guess the USDA's senior technical information specialist did not read up on fungus before dishing out the advice.  And then a phrase like "mold spores's roots"?  What?  Spores germinate and produce filaments that grow into the organism's body, a mycelium. Do you find this language particularly creepy? A junior information specialist would have used the word "icky" instead. 
What they were trying to explain here is that the mold extends far beyond the portion that you can generally see.  But the tone of the warning is needlessly alarming. TPP's rule is simpler, if you can easily remove the visible mold by trimming it away, like the bit on the edge of the slice of bread above, then the bread is not sufficiently moldy to avoid eating it, especially after you've toasted it and spread it with peanut butter, jelly, or Vegemite, which is made from fungus (yeast) itself.  Some molds like Penicillum are used deliberately to infect certain foods to prevent other molds and bacteria from growing because these molds are famous for producing antibiotics like the well-known penicillin. And better the mold you know than some other spoilage organism.
So how much can you trust the advice from someone who doesn't get even the basic technical facts correct, and uses alarmist language?  Too many communication courses, not enough science on Marianne's CV is TPP's guess.



Italian bread with no salt - an update

The question of why Italian bread has no salt has raised two hypotheses and here are some of the ideas about this from the local natives, Italians themselves. First, they all agreed on exactly one thing; no salt in the bread is a Tuscan thing. Further south and further north in Italy the bread has salt. So it's only Tuscan bread that tastes bland.  Who knew? The favored hypothesis is that Tuscan cured meats, their ham and their favorite salamis are pretty salty, so you just don't need salt in the bread too. The historic hypothesis says that during its many wars with other city states, coastal dwellers sought to punish/subdue Florence by withholding salt. Florence responded by basically saying "We don't need your stinking salt; we'll make our bread without it." But this is a mighty long time keep punishing yourself out of regional pride. These explanations are not incompatible except if you have no salt for bread you also have no salt for curing meat. The things you learn when you travel.

March Snow - Signs of Civilization

It has been showering snow all day, and while it won't accumulate, it makes the day dreary as early March days often are. Saturday's quest was for gorgonzola dulce to use in a very interesting pasta for tomorrow (and probably the next couple of days too). Thirty years ago when we moved to this little part of heaven on Earth it was a total gastronomic wasteland. The "best" Italian restaurant around served ickily sweet bread; totally disgusting. And for a fellow who grew up in areas of New York state with very large Italian populations, it was unthinkable. Decent cheese, imported cheese, real bread, and decent wine were just AWOL and required a road trip to Chicago. What a difference a generation has made. My quest required but a single stop. Maybe it will snow tomorrow too, but cooking cheers me up. As will the cheese and ciabatta bread. These are signs of real civilization.
