Is the following case a problem of "borer" (separating) on Shabbos?
We know there can be "borer" even when dealing with two edible foods, one food that a person does want to eat and the other that the person doesn't want to eat. Suppose someone used a spoon to take food from a dish, and wound up with both chicken meat and beef, but he doesn't want the chicken meat. If he tilts the spoon in order that the chicken meat falls off, leaving the beef on the spoon, is this a problem of borer?
(I picked the example of meat because that's what the actual case was, please don't read into it too much. You can change the meat for any other two foods. Apples and pears, etc, etc, etc.)
