My first is this silicon spatula. It’s construction isnt just a silicon tip with wooden handle. Its the red silicon for much more of the handle, which I’ve felt makes it easier to clean and last longer, since gunk isnt getting wedged between the handle and tip. I like it so much I have two.
The second is probably just a spray bottle with water and dish soap. I clean up messes and the stove and countertops with it, and it’s incredibly convenient.
Knife, obv. My second favourite is also a knife. My third favourite is another knife. My fourth favourite is an ancient wooden spatula which has become exactly the right shape for my fifth favourite enamelled Dutch oven.
