things people ask

• How many olives are in a cup?
  Pitted, that's roughly 40-50 medium olives — about 6-8 olives per ounce, and a cup is around 5 oz at 142 g. Castelvetrano run larger and pack fewer per cup; Niçoise are tiny and pack more. For olive bread or pasta puttanesca, count by weight rather than number, since varieties differ enough that a 'cup' can swing 20-30 g either way.
• Should olives be drained before measuring by cup?
  Yes — the 142 g figure is drained weight. Brine clinging to a cup of olives can add 15-30 g of liquid, which throws off the salt balance in tapenade or olive bread dough. Tip them into a sieve for a minute, or pat with a paper towel if the recipe is sensitive to extra moisture, like a focaccia where wet olives can pock the crumb.
• Do sliced and whole olives weigh the same per cup?
  Close, but sliced packs slightly tighter — a cup of sliced olives can run 145-150 g because the rings nest, while whole olives leave more air gaps and land near 138-142 g. For a Greek salad where you want visible olive halves, measure whole; for puttanesca where they break down anyway, slicing first gives a more consistent cup.
