A Christmas Eve Ingredient
Aguonos are most visible at Kūčios, the Lithuanian Christmas Eve meal: aguonpienis with kūčiukai is one of the table's most recognizable dishes.
They are also used in cakes, rolls, buns, šimtalapis, and other festive baked goods.
Why Soak and Grind Them?
A dry poppy seed is hard and gives up little flavor. Soaking softens the seeds, while grinding releases aroma and oiliness.
That is why a good poppy seed filling is cohesive and fragrant, not just a mixture of dry seeds.
Aguonpienis and Fillings
For aguonpienis, ground poppy seeds are diluted with water and sweetened. For filling, the mass is thicker and often includes sugar, honey, raisins, or nuts.
Both forms rest on the same base: soaked and ground edible poppy seeds.
Legal and Safety Note
When discussing poppies, it is important to separate edible seeds from the cultivation of the plant. Use only seeds intended for food. According to the Universal Lithuanian Encyclopedia, edible poppy seeds come from opium poppy (Papaver somniferum); because all parts of the plant contain alkaloids such as morphine and codeine, cultivation is regulated, so cooking uses purchased food-grade seeds.
Poppy seeds contain a lot of oil, so old or poorly stored seeds can become rancid.
Recipe
How to prepare poppy seed filling
For poppy seed filling, the seeds need to be soaked and ground. Dry, unground poppy seeds do not release much flavor and remain loose.
Ingredients
- 250 g edible poppy seeds
- Hot water for soaking
- 100 g sugar or honey
- 50 g butter or a plant-based alternative, depending on the dish
- A handful of raisins or nuts, optional
Method
- Rinse the poppy seeds, cover with hot water, and leave for at least several hours.
- Drain and grind several times, or crush.
- Mix with sugar or honey and warm briefly.
- Fold in raisins or nuts, if using.
- Use for rolls, cakes, buns, or dilute the mixture to make aguonpienis.
Notes
Use only food-grade poppy seeds bought from a shop.
Cultivation of opium poppy is restricted in Lithuania, so this page does not give growing advice.
