First major improvement in your cooking: Using mass measures instead of volume. Using mass will VASTLY improve your consistency in recipes. It’s also much easier in that you can build your dish in one bowl. Just put the bowl on the scale, tare it, then measure directly into the bowl, tare it again, and add your next ingredient. Finally, scaling recipes up or down is far easier and consistent using mass.
Buy (that’s right, I said “buy”) a digital scale. In fact buy two (possibly even 3!) 1st: 5kg, then 500g, then maybe a 10kg. But they don’t have to be expensive. My first scale came from Harbor Freight (Harbor Fright for many of its tools) and it was okay. Ikea has some nice ones, but this little gem from Amazon is my go to and its a whopping $10.
That 5 kg scale will do for most things, but it’s pretty useless for measures less than a gram. Which leads to your second scale: <1kg . The smaller range is accurate for small measures (<3g) and reliable down to +/- 1/10th of a gram. I scored this Vitafit 500g Digital Pocket Gram Scale. Its says it good to 0.001g but I only expect 0.01g precision.
It’s a must-have for weighing seasonings.
