Poppy seeds: grinding and storage
A cup of poppy seeds weighs about 145 g. For pastry fillings like strudel and kolache, grinding the seeds releases their flavor and a creamy texture; for topping breads and bagels, use them whole. Because they're high in oil, poppy seeds turn rancid faster than most pantry items.
Store them in the fridge or freezer and give them a quick sniff before baking — fresh seeds smell faintly nutty, not sharp.

How poppy seeds compares with other nuts & seeds
A cup of poppy seeds weighs 145 g, which puts it 10th by weight among the 13 nuts & seeds on this site. Its nearest neighbours are sesame seeds at 144 g and flax seeds at 150 g per cup.
That gap matters when you substitute by volume: use a cup of flax seeds where the recipe wanted poppy seeds and you have added about 5 g extra — 3% more than intended. Weighing instead of scooping removes the problem.
