things people ask

• How much peanut butter is in a standard 16 oz jar?
  A 16 oz jar holds 454 g, which works out to roughly 1.7 cups at 270 g per cup. That's why peanut butter cookie recipes calling for 1 cup leave you with a clear half-jar remainder. For batch satay sauce or peanut noodles where you'd use 1.5 to 2 cups, plan on opening a second jar or scaling the recipe to match the jar.
• Does natural peanut butter weigh the same per cup as commercial?
  Close, but not identical. Commercial brands like Jif or Skippy are emulsified with stabilizers and pack denser — typically right at 270 g per cup. Natural peanut butter, once stirred to recombine the oil, runs slightly lighter at 250-260 g because air gets folded in during stirring. For cookies and fudge, the difference is small enough to ignore unless you're scaling up a triple batch.
• How do I measure peanut butter for a cup without it sticking everywhere?
  Lightly oil the measuring cup or use a flexible silicone cup, then push the peanut butter in with a spatula and level the top. For peanut butter cookies and fudge, the gram weight matters more than the cup line — 270 g into the bowl gets you a consistent dough whether your cup was packed loose or firm. Water-displacement tricks work but add moisture you may not want.
