aggressiOn: "...it was disgusting. Are all kosher foods like this?..."
Yes.
You're not supposed to chew Kosher food...that's why it tasted bad.
Also, there's a rule that says that even if Kosher food says "Kosher" on it, it's really not, unless you eat two at a time of whatever food you want.
So, go get two more of those pickles, and swallow them both whole. Don't attempt to chew them.
That's it!
Now you're really "eating Kosher".
