I can't resist anything to do with cooking. What I use constantly:

Popover pan & I'm glad I moved this with me since I've never seen one in Mexico.
Microplanes, different sizes
A ruler, a necessity for me with baking

Thermapen which I got in London & is great for testing the temp of breads in addition to meat.

I'm terrible about sharpening knives so I love the ceramic ones that are sharper than any of my "good" knives.

Silpats & parchment paper
Cuisinart Ice Cream Maker, though I have to pre-freeze the canister.
Cast Iron Skillet

I'm terrified of pressure cookers. I remember when they exploded & now I'm cooking with propane at a high altitude. I'm in no hurry anyway.

Deep fryer
Kitchen shears - used almost daily
Electric kettle. I'm a tea purist so use loose leaf tea, etc.
Bench scraper, again I use it almost daily.
Kitchen-Aid & Cuisinart
And don't get me started on cookbooks...
