Laser thermometer. It makes cooking things at really specific temperatures a lot easier.
Some long-handle sundae spoons. They're incredibly useful for getting to the bottom of a deep jar or yogurt tub.
Collapsible screw-together travel chopsticks. They take up virtually no space, come with their own holder so they stay clean, and you've always got some nice chopsticks to eat with.
Blue painter's tape. You can label anything (especially stuff that's going into the freezer), and it'll peel off again without leaving any residue.
Beaded reusable cable ties. It's always nice to be able to tie up a power cord.
A nice headlamp. It's really nice to be able to put on a headlamp and have your hands free when you're doing stuff outside at night. Fair warning: you may fall down a nice flashlight rabbit hole.
