About measuring peanut butter
Peanut butter is thick, dense and stubbornly sticky, so one US cup weighs about 258 grams. It is one of the least pleasant ingredients to measure by volume, since it clings to the cup and refuses to pour or scrape out cleanly. Weighing straight into the bowl is far tidier: zero the scale with the bowl on it, then spoon in peanut butter until you hit the grams. The same trick works for other nut butters, which have similar densities.
Weigh sticky peanut butter straight into the bowl. Scraping it out of a cup wastes a lot.
