are green olives with blue mold in jare safe to eat
Unless mold is an actual part of the food (as in blue cheese or brie), do not eat moldy food.
Provided the container stays sealed, pretty much indefinitely. Olives are usually packed in brine (very salty water). Brine prevents spoilage and preserves the food that is packed in it. So long as the container stays closed (preferably sealed), the olives inside it will remain safe to eat. After several years, the quality of the olives (taste and texture) may degrade, but they will remain safe to eat. This of course is assuming they were prepared correctly and sealed in a sanitary manner.
The ones in a jar...
No, 'recently' is an adverb, a verb modifier. An adverb describes the action of a verb. For instance, in the sentence, "I carefully unscrewed the jar of olives," the adverb is carefully. Carefully is an adverb because it describes the verb, or, in other words, answers the question, "How did you unscrew the jar of olives?" " I carefully unscrewed the jar of olives." or, as in your case, "I recently unscrewed the jar of olives."
That depends on the type and where you buy them
Black olives, hot pepper flakes, olive oil and oreganoare traditional ingredients in Armenia's black olives with seasoning.Specifically, the black olives are sprinkled with oregano and then with pepper flakes. The olives and the seasonings are mixed together gently until blended. The ingredients then are spooned into a jar that must have a wide mouth. When all of the seasoned olives are in the jar, enough olive oil is added to fill the jar three-fourths (3/4) full.The jar needs to be capped tightly and stored in a cool place. Over the next week, the jar needs to be turned upside down two or three (2-3) times every other day.
Yes ; but the juice is very - very salty .
Depends on the size of the jar, if they are pitted or stuffed and how large they are.
I am sure they are still edible if they are not showing signs of decay and or mold. Most olives are pickled in brine which preserves them for a long time without the need for refrigeration. If they have been kept sealed in a jar they will keep much longer than 4 days--probably weeks and possibly months. If the olives are not pickled (as some ripe olives are not), and they are left exposed to the open air, they might begin to spoil within 4 days. Otherwise there is not likely to be a problem.
It would be safe only if it was properly processed. Just sticking any old food into a jar and then closing it would not make it safe.
It'll take a few days to mold
Yes, the noun olive is a countable noun; one olive or a jar of olives.
