# If there’s a group of indentical items that group isn’t considered a mixture and may be separated without violating borer. <Ref> Rama 319:3 rules that it's permissible to seperate peices of fish by the size since it's all one type of food. Mishna Brurah 319:15 writes that even though the Taz argues on the Rama, most achronim agree with the Rama. So write's the Shabbos Kitchen (pg 87-88) that there's no borer when seperating indentical objects. </ref>

# However if there’s a difference in the taste, function, or quality in the foods the group of items is considered a mixture. However, items of different sizes that are identical in taste, funcation and quality don't form a mixture. <ref> Shabbos Kitchen (pg 88-91) outlines four ways to distingish items in a group to call it a mixture and not a group fo identical items. The four main catogories are taste, function, and quality. </ref>
# However if there’s a difference in the species, taste, function, or quality in the foods the group of items is considered a mixture. <Ref> Shabbat Kitchen pg 90 </ref>
## Foods that have a different taste are considered a mixture. For example, cooked and baked apples together are considered a mixture. <ref> Shabbos Kitchen (pg 89) </ref> Another example is boiled and roasted chiken pieces together are considered a mixture. <ref> Mishna Brurah 319:15, Shabbos Kitchen (pg 89) </ref>
# The following are examples of groups that constitute a mixture being that the items are different in some of the above respects:
## Foods that have a different function constitue a mixture. For example, soup spoon and teaspoons together would form a mixture. Similarly, kitchen and table knifes, or large and small plates, or spoons and forks together create a mixture. <ref> ayil meshulash pg 16, Shabbat Kitchen pg 90 </ref> Another example would be matzah meal and matzah chunks mixed together would be a mixture. <ref> pri megadim m”z 319:2, Shabbat Kitchen pg 90 </ref>
* cooked and baked apples have different tastes <Ref> Shabbat Kitchen pg 90 </ref>
## The definition of foods of different quality is when one food is desireable and one is edible but only out of nessecity. <ref> Mishna Brurah 319:7, Shabbat Kitchen pg 90 </ref> For example, fresh and spoiled grapes together form a mixture. <ref> Shabbat Kitchen 91 </ref> Similarly,  cooked and burnt meats form a mixture. <ref> Mishna Brurah 319:15 </ref>  
*boiled and roasted chicken have different tastes <ref> Mishna Brurah 319:15 </ref>
# However, the different size of items in a group don't cause the group to be considered a mixture unless the difference in size changes it’s function <ref> Rama 319:3, Shabbat Kitchen pg 90 </ref>
* soup spoon and teaspoon have different functions <ref> ayil meshulash pg 16, Shabbat Kitchen pg 90 </ref>
# Some are lenient regarding attached mixtures such as a grapes cluster and in a case where it's costumary to remove the bad before eat, it's permissible to remove the bad from the good immediately before eating. <ref> http://www.dailyhalacha.com/displayRead.asp?readID=818&txtSearch=borer in name of Menuchat Ahava by Rabbi Moshe HaLevi</ref>
* kitchen and table knife have different functions <ref> ayil meshulash pg 16, Shabbat Kitchen pg 90 </ref>
* large and small plates have different functions <ref> ayil meshulash pg 16, Shabbat Kitchen pg 90 </ref>
* spoons and forks have different functions <ref> ayil meshulash pg 16, Shabbat Kitchen pg 90 </ref>  
* matzah meal and matzah chunks have different functions <ref> Pri Megadim M”Z 319:2, Shabbat Kitchen pg 90 </ref>
** It’s permissible to take full matzah boards from a box which has broken pieces in order to have two full boards for Lechem Mishna even if one does this by taking out one board at a time and putting back the broken boards. <Ref> Shemirat Shabbat KeHilchata 3:28 </ref>
** However, one may not take all the broken pieces out of a stack of matzah’s with whole and broken boards of matzah unless one plans on using all the matzah (broken and whole) for that meal. <Ref> Shemirat Shabbat KeHilchata 3:28 </ref>
# Something as having a different qualities if the undesired one is eaten only out of necessity <ref> Mishna Brurah 319:7, Shabbat Kitchen pg 90 </ref>  
* fresh and spoiled grapes have different qualities <ref> Shabbat Kitchen 91 </ref>
* cooked and burnt meats have different qualities <ref> Mishna Brurah 319:15 </ref>
# If only part of the fruit is spoiled one may remove that fruit from a mixture of good fruits. However, an altogether rotten fruit may not be removed from a mixture of good fruits.  <Ref> Shemirat Shabbat KeHilchata 3:25 </ref>
===Items of different sizes===
# If items of a mixture of different sizes, that doesn’t make it a mixture unless it changes it’s function. <ref> Rama 319:3, Shabbat Kitchen pg 90, Shemirat Shabbat KeHilchata 3:24 </ref>
# Color and size are factors that do not make items to be considered different unless the size or color changes the function. <Ref> Shemirat Shabbat KeHilchata 3:27 </ref>
# One may take items from a mixture of two different types but should be careful not to separate the different types by size. For example, one shouldn’t assort a basket of apples and pears by separating by size. <Ref> Shemirat Shabbat KeHilchata 3:26 </ref>
# One may separate different items some of which are more aesthetically pleasing from others which are less aesthetically pleasing as long as both objects are equally useable. <ref> Shemirat Shabbat KeHilchata 3:28 </ref>
