Is this gift ok for a Kosher Jewish family?

I agree and you are making an assumption the items are Kosher meaning they very well might not be and it would be something they couldn't use and a waste of your money.

Food gifts..even spices are not a good choice in this situation.

I would go with a plant/flowers or something non food as a hostess gift.

There's very little that IS Kosher that people couldn't use because it was if they weren't. You'd probably be surprised how much in your own pantry is Kosher.

That said - go with flowers, or a bottle of Kosher wine, can't go wrong with a traditional hostess gift.
