Poppy seeds от John Spottiswood

These tiny, nutty seeds are typically used in baked goods, but some cuisines also use them in savory dishes. Europeans prefer black poppy seeds, while Indians prefer white, but the two kinds can be substituted for one another. Since poppy seeds are high in fat, they tend to go rancid quickly, so buy small amounts and store them in the refrigerator. Consuming poppy seeds can result in a false positive on a drug test.
