What Blessing Do I Make?
Answer: It is a fact that with very few exceptions products certified as kosher have no indication on their labeling as to which blessing is to be made upon consuming them. A chassidic leader in Israel conducted a campaign some years ago to compel local companies to include this information on their packaging but did not succeed. There are almost certainly reasons for this, so it will probably be an exercise in futility to pursue the course of customer pressure.
What may be advisable is to contact the heads of the certifying organizations and ask them to provide you with a list of the products under their supervision and the blessing that must be made. If this fails to produce results, you can always consult your local Orthodox rabbi or one of the many books and pamphlets that list a wide variety of foods and the blessings to be made upon them.
