Poppy Seeds in the Kitchen: Flavor, Nutrition and Honest Safety Notes

Poppy seeds are tiny blue-gray or white seeds from the opium poppy plant. They have been used in cooking for thousands of years, from European pastries and bagels to Indian curries and Middle Eastern sweets. Culinary poppy seeds are a normal food, but there are a few things worth knowing before you use them regularly.

Blue or white?

Blue-gray poppy seeds are common in Europe and North America, often used in cakes, rolls and fillings. White poppy seeds, sometimes called khus khus, are popular in Indian and South Asian cooking, where they are ground to thicken sauces and add a rich, nutty creaminess. The flavor is mild, a little sweet and best released when the seeds are toasted or crushed.

What is in poppy seeds?

A tablespoon (about 9 grams) of poppy seeds has about 1.5 grams of protein and a gram or two of fiber, and a notable amount of calcium, along with magnesium, iron and zinc. They are small, so you eat them in small amounts, but baked goods and sauces made with them can add a useful extra bit of minerals. Their fats are mostly unsaturated.

How to use them

Sprinkle whole seeds on breads, crackers and bagels before baking. Fold them into muffin or cake batter, or make a classic poppy seed filling by simmering ground seeds with milk and sugar. Toast and grind white poppy seeds to thicken curries and kormas. Stir a teaspoon into salad dressings, or into noodles and roasted vegetables. They also make a lovely crunchy coating for fish or cheese.

A note on drug tests

Poppy seeds can carry tiny traces of natural compounds from the plant on their surface. Eating a lot of poppy seed foods, such as a large poppy seed bagel or a slice of poppy seed cake, has in some cases been linked to a positive result on a workplace or sports drug test. If you face testing, it is wise to avoid poppy seeds for a couple of days beforehand and let the testing body know.

Buy and store with care

Buy from a reputable seller of food-grade seeds, and avoid unusually large quantities of raw, unwashed seeds or homemade poppy teas, which can carry higher levels of these compounds and have caused harm. Store seeds in an airtight jar in a cool, dark place, or in the fridge for longer life, because their oils can turn rancid.

Who should check first?

Anyone who has regular drug testing, who is pregnant or breastfeeding, who takes strong pain medicines, or who has a history of opioid sensitivity should ask a doctor or pharmacist before eating poppy seeds regularly. People with seed allergies should be cautious. Because poppy seeds are tiny and sticky, they can be tricky for people with swallowing difficulties or dental appliances.

Used in ordinary kitchen amounts, they are a flavorful way to add variety, and they work well alongside other seeds in a mixed pantry.
