These wonderful spatulas are probably the piece of equipment I’m asked about the most, and I love them dearly! If you’ve seen me use them in my videos you’ll know they’re wonderfully flexible and have a fine edge that’s perfect for getting every last drop of a concoction out of a beaker.
I’ve tried quite a few different long, thin spatulas, and the best ones are the Norpro Silicone Jar/Icing Spatula. You can get them on Amazon (USA / Canada). I recommend getting a few of them as they’re really useful. Just be careful with the handles when washing them—they can snap if you’re really scrubbing away at the blade and applying a lot of pressure to the handle.
