This question already has an answer here:
Next week I will be flying to the US from Canada, and I was planning to bring a couple jars of homemade strawberry jam as a gift for my host.
Unfortunately, both countries' respective border services websites make no mention of whether jam is allowed across the border. It seems that canned fruit is generally permitted, but I don't know whether jam could be included as a "canned fruit" (or furthermore, whether homemade preserves are even permitted under this guideline).
Thus my question is: can a traveller bring a small quantity (2-3 jars) of homemade fruit jam from Canada into the US? (Answers that reference an official/government source would be preferred)
