Ina says that you don't need much to have a great functioning kitchen, just chose the right stuff. Here's some tools that I use all the friggin time AKA items I wish I'd had the foresight to register for before I went out and bought them myself.
MIXER. Hand mixer or stand mixer. Obviously you know what I prefer but I still own and use my hand mixer as well as the sexy beast known as my kitchen aid stand mixer.
STRAINER. To keep lemon seeds from falling into my soup and OJ from being to pulpy.
POTATO MASHER. Nothing else smashes potatoes quite as well or anything else that needs smashing like white beans for my 15 minute white bean soup.
STAINLESS STEEL MIXING BOWLS. I got mine from Costco. They have a rubber bottom so they wont slide around AND they each come with a cover so I can transport what I make to Aunt J's for Thanksgiving or store in the fridge when I'm done. UH-MAZING.
FUNNELS. Yes, funnels, use them all the time. To refill the olive oil thing, to put my tea in a travel mug, to put mustard seeds into a jar. Trust me, the $2 are worth it.
TONGS. To grab hot stuff, to flip hot stuff. To be HOT STUFF.
SPATULA. I own four. Three regular sized, one tiny. They are indispensable.
BAMBOO SPOON. A million times better than a regular wooden spoon, it doesn't stain and I dunno, it's just awesome-o.
Also, I have a flour sifter, I have used it to make one item repeatedly but the rest of the time I just take a wooden spoon and mix the dry ingredients. Lazy? Defeats purpose? My cupcakes come out just fine thankyou.
