zest, rum and vanilla with raisins, heavy cream, cinnamon, and chopped blanched almonds or walnuts added. For sweet baked goods, sometimes instead of sugar a tablespoon of jam, or other sweet binding agent, like syrup is substituted. The poppy seed for fillings are best when they are finely and freshly ground because this will make a big difference in the pastry filling's texture and taste. Poppy seed paste is available commercially, in cans. Poppy seeds are very high in oil, so commercial pastes normally contain sugar, water, and an emulsifier such as soy lecithin to keep the paste from separating. Commercial pastes also contain food preservatives to keep them from becoming rancid. In the United States, commercial pastes are marketed under brand names including Solo and American Almond. Per 30 gram serving, the American Almond poppy seed paste has 120 calories, 4.5 grams fat, and 2 grams protein. Oil Poppy seeds are pressed to form poppyseed oil, a valuable commercial oil that has multiple culinary and industrial uses. Other uses Poppy seeds are often used as bird seed, in which case they are usually called maw seeds. Use by cuisine Poppy seeds are used around the world in various cuisines. European cuisine Across Europe, buns and soft white bread pastries are often sprinkled on top with black and white poppy seeds (for example cozonac, kalach, kolache and kołacz). The seeds of the Czech blue poppy (food safety cultivars Papaver somniferum) are widely consumed in many parts of Central and Eastern Europe. The sugared, milled mature seeds are eaten with pasta, or they are boiled with milk and used as filling or topping on various kinds of sweet pastry. Milling of mature seeds is carried out either industrially or at home, where it is generally done with a manual poppy seed mill. Blue poppy seeds are widely used in Austrian, Croatian, Czech, Danish, German, Hungarian, Lithuanian, Polish, Romanian, Russian, Serbian, Slovak, Slovenian, Turkish and Ukrainian cuisines. The states of former Yugoslavia (notably North Macedonia and Serbia, but also Croatia and Bosnia) have a long tradition of preparing poppy seed pastry (štrudla, baklava, pajgle) and dishes (pasta with poppy seeds). In Slovenia blue poppy seeds are used in traditional dishes such as prekmurska gibanica and makova potica. In Poland, Hungary, Lithuania and Eastern Slovakia, a traditional dessert is prepared for the Kūčios (Christmas Eve) (in Hungarian: mákos guba) dinner from poppy seeds.
