Question/Answer:
Are the Muffins at Starbucks in Canada Kosher?

Many of the muffins sold at Starbucks stores in Canada are manufactured at facilities that are kosher certified by COR. According to Jewish law, one must see a kosher symbol on a product’s packaging in order to guarantee that the particular product is in fact kosher. Many Starbucks locations keep the boxes used to package the muffins on hand and these boxes do carry the COR Kosher symbol. Kosher consumers may ask baristas to see these boxes so that the consumers may verify the kosher status for themselves.

If I see a mix of some sort (i.e. muffin mix) listed on your website as kosher but it is baked in a non kosher restaurant or coffee shop is it still kosher?No. Food products such as muffins sold at restaurants or coffee shops that are not sealed with a reliable kosher certification symbol should not be considered kosher. Many of these mixes are produced at kosher plants that produce a variety of different products for a host of different companies. But once the mixes are baked in the non kosher restaurant or coffee shop's ovens which also bake other products many of which contain non kosher ingredients, or even pork and the like, they are no longer kosher. Therefore, in these instances, only products that are sealed and carry a reliable kosher certification symbol on the package can be considered kosher.
I've seen some Heinz baby food in plastic containers that has a COR, but the jar version of the same product does not. Is this a mistake? Is the jar version of the product kosher certified?No.

Many products, both kosher and non kosher, share production lines. If the kosher products are made after non kosher products a "kosherization" process usually needs to take place. The plastic Heinz baby food containers in question are produced in a smaller factory where there are very few scheduling conflicts to attend to and thus kosherization can be done easily. The glass bottles are produced in a different facility, one that is very busy, and the scheduling conflicts are too great to allow for koshering of the equipment between runs. Therefore, they are not kosher certified.
Are Baskin Robbins Birthday Ice Cream Cakes Certified Kosher?No. Most, but not all of of Baskin Robbins' ice creams are certified kosher in Canada by the COR. The Baskin Robbins birthday cakes use Baskin Robbins ice cream, but they also contain other non kosher certified ingredients used in the writing of the birthday message and other such decorations. So at least at the moment, Baskin Robbins birthday cakes are not certified kosher. However, Baskin Robbins ice cream cakes that are sealed and carry a COR certification are indeed kosher.
I see so many different kosher symbols. How do we know which ones are accepted?There are over 1000 different symbols from all over the world. The determination of which are acceptable has become a difficult task. We generally recommend the well-known, Orthodox certifications which have a skilled rabbinic staff who make the halachic decisions for their organizations. The organization that is most suitable to your standards should be discussed with your Rabbi.
Why do many products in the United States have an OU or other acceptable symbol on such products as cookies and granola bars, but the same brands are not under supervision in Canada?

One of the main reasons for this is that the product is made by a different manufacturer who does not have kosher endorsement. A good example of this is the Kit Kat chocolate bar. Kit Kat in the United States is made by Hershey Foods Corporation, which has the Orthodox Union certification. Here in Canada, it is made by the Cadbury Schweppes group which does not have kosher endorsement for Kit Kat. The formula may be the same but the raw materials and sourcing of the ingredients may not. The glycerin used in Canada may be from an animal source whereas the American kosher product would use glycerin from a kosher source.

Why can’t we just read the ingredients on a label and if everything is kosher, use that product?

Food manufacture is an extremely complex process. Many ingredients that are not commonly known are problematic. For example, Lipase is extracted from animal tongues or pancreases, Glycerides are used in many gums and candies and are usually refined animal fat, or Polysorbates which are often combined with glycerides and as such contain animal fat. But that’s not the whole story. Even if all of the ingredients were kosher, what about the equipment they are made on? There could easily be considerable cross contamination that would render the product non kosher. For these reasons amongst others, a reliable kosher certification on a food product is a must.

Why are grape flavours not kosher? Wine (and grape juice) have always been an extremely important part of Jewish ritual. For that reason, all wine and grape juice must be made by people of Jewish faith and carry reliable kosher supervision. Regarding flavours, many grape flavours are not truly artificial as listed. Besides the many other components which are used to make a grape flavour, which may not be kosher, e.g. ethyl oenanthate, the use of concentrated grape juice is common.
I want to convert my kitchen to kosher. How do I go about it? Mazal tov! Kashering your home can be both a spiritually rewarding and educational experience. The COR would be honoured to help you undertake this process and will even send a rabbi to your house to discuss the particulars
How does the kosher certification process work exactly?

The requirements include a thorough ingredient review which includes processing aids and an inspection of the plant. We make scheduled and unannounced inspection visits to the company to review their food processes and raw materials. There is a contractual agreement entered into between the company and the COR Council along with a supervision fee.

I was told by a company that was taken off the kosher list that this happened because the rabbis were too busy to come to bless the company. Is this true?

Kosher certification is a rigorous process. It has nothing to do with “blessing.” In fact, the only “blessing” we do is blessing companies with much success once they have fulfilled the rigorous requirements of the certification process.. It is generally because of non-compliance with the requirements of the written agreement that a company is delisted.

What are the numbers after the COR symbol on labeled products?

The numbers are our way of identifying a registered manufacturing facility. The COR without a number on a processed food may raise a question as to its authenticity.

Do herbal teas require kosher certification? Many teas do not require kosher certification. But many herbal teas contain natural and/or artificial flavours which require kosher certification. The terms “natural and artificial” are generally misunderstood by the consumer. These two words could mean that there are another 10-50 other ingredients included but are too long to list. In the flavour industry there are a number of non-kosher components which are hidden behind the term “natural and artificial” flavours and colours.
Can I go to any bulk store and purchase bulk items such as raw peanuts, nuts, flour, cornmeal?

If they are truly raw, with no coating, flavouring, dusting etc., bulk products can be purchased if they are items that do not require kosher certification and are kept in a clean, insect-free environment.

Are juices in tetra pack form all right to buy? Also, what about the canned fruit beverages like Delmonte? Tetra pack juices require kosher certification due to the issue of processing non-kosher products on the same equipment. This could include grape juice, Clamato (i.e. clam juice) or dairy products.

I was told that I could purchase sliced fish from York Fish Store or Fortinos as long as I see the signs of a kosher fish having scales and fins and I rinse the fish when I get home. It is always preferable to buy fish at a supervised fish market because then there would be no problem buying filleted or ground fish. Jewish law tells us that a kosher fish must have fins and scales. In the absence of fins and scales how could you tell what kind of fish it is? What about the cutting and handling of the fish? If you are prepared and have the time to watch the fish processed from the removal of the scales and cutting it up with a clean knife, then “your” hashgacha will allow you to use the fish. It also will require you to wash the fish again at home. You should also be familiar with kosher scales. The kosher scales, cycloid and ctenoid, are the easily removable scales that do not tear the skin or flesh of the fish. The ganoid and placoid scales cannot be removed without tearing the skin and a fish with this variety of scales would not be kosher.
Do all seasonings and spices require kosher certification? Pure seasonings that do not have any mixtures of other ingredients such as spice oils or spice blends are generally OK. Any spice or seasoning from Israel requires proper kosher endorsement.
Some product labels state that there may be milk floating around in the air. Does this make the product dairy? What about disclaimers about allergens in the air? According to halacha, dairy components floating in the air in parts per million, do not make a product dairy.
If I buy a generic product with a COR, will it always have a COR on the label?

NO. Not all “Generic Products” are necessarily produced at kosher certified companies. The store brand name labels use manufacturing companies, some of which have kosher certification and others that do not. You cannot assume that all their products are kosher and you must look for the kosher endorsement each time you buy the product.
