Zojirushi Fuzzy Logic rice cooker: use it all the time
Thermapen: Husband loves it
Pizza steel: invaluable
Tamaki Gold sushi rice: delicious
Mala Market: pricey, but a great resource for some hard-to-find products I can't find (or I'm to lazy to look for) in Oakland Chinatown
No doubt there's more, but I can't think of anything right now
Oh just thought of another: Bamix immersion blender. Don't know how I lived without it.
Not an unqualified success: Trader Joe's recommendations. I'm somewhere about 50/50. There have been a few good recs, but TJ's is only useful for a few things in MHO. I don't buy a lot of appliances at this point, so no Instant Pot or CSO or SV or blast chillers, etc.
