My pickled green beans and pickled beets are very warmly received and often consumed on the spot. Apple butter travels well, and you don't have to make it too sweet. My Dad's horseradish was always well-received (watch out for those fumes!)
Pickled baby onions
Pickled garlic (you might have some around...
Pickled crabapples like Gramma made, you could also use sliced regular apples
Dehydrate your own stuff, like fancy wild mushrooms from the grocer, some mushroom powder in a cool shaker
Some of your nice homegrown garlic, dehydrated, also in a cool grinder
