Digital Food Scale

A $12 digital kitchen scale is the single biggest upgrade for anyone who bakes. Measuring cups are wildly inconsistent — a "cup" of flour can vary by 30% depending on how you scoop it. A scale eliminates the guesswork entirely. It also makes portion control effortless, halving or doubling recipes trivial, and following European recipes (which use grams) possible. The OXO Good Grips and Etekcity models are both under $15 and accurate to the gram. Professional bakers consider scales non-negotiable. Home bakers should too.
