Poppy milk, Christmas Eve aguonpienis
What is aguonpienis?
Aguonpienis is poppy milk: soaked poppy seeds are crushed with water until the liquid turns pale and takes on a nutty poppy flavor.

At Kūčios, it is most often eaten as a sweet cold soup with kūčiukai.
Aguonpienis in the Kūčios Tradition
Aguonpienis belongs to fasting dishes because it is made without animal products. It complements the grain, fish, mushroom, and vegetable dishes of the Christmas Eve table. The Universal Lithuanian Encyclopedia lists aguonpienis among surviving sacred Kūčios foods together with prėskučiai and cranberry or oat kisielius.
Its link with kūčiukai is essential: kūčiukai alone are dry little baked pieces, while aguonpienis turns them into a sweet cold soup. For that reason the two dishes are usually understood as a pair.
In the imagery of winter holidays, poppy seeds are associated with calm, sleep, and memory.
Crushing or Blending?
In the past, poppy seeds were crushed in a mortar or ground; today a blender is often used. The goal is the same: break the seeds so they release a white liquid.
Strained aguonpienis is smoother; unstrained aguonpienis is richer and thicker.
