Poppyseed Filling for Hanantaschen

A full pound of poppy seeds ground fine, mixed with honey, sugar, and egg into a thick, nutty-sweet paste. This is the traditional mohn (poppy seed) filling for hamantaschen, the triangular Purim cookies that are as much about the filling as the dough.

Washing the poppy seeds in boiling water first removes any bitterness and surface dust. Drying them overnight on a clean cloth is time-consuming but essential. Wet poppy seeds won’t grind properly and will turn the filling gummy instead of producing the fine, sandy texture you want.

Grinding with the finest blade of a food grinder (or pulsing in a food processor) breaks the tiny seeds open and releases their oils. This is what transforms raw poppy seeds from crunchy, bland specks into a rich, almost paste-like filling with a deep, earthy flavor that’s impossible to get from store-bought filling.

The honey and sugar balance each other. Honey provides moisture and floral complexity while sugar adds clean sweetness. The egg binds the mixture so it holds together inside the hamantaschen dough instead of spilling out during baking. Optional nuts and raisins add texture and fruity sweetness if you like a chunkier filling.

Chef Tips

• Grind the seeds in small batches for the most even texture. Overloading the grinder leaves some seeds whole.
• The filling should be thick enough to hold its shape on a spoon. If it’s too loose, it will leak through the dough seams.
• One tablespoon per hamantaschen is the right amount. More than that and the triangles won’t close properly.

Variations

• Lemon poppyseed: Add the zest of one lemon to the filling for a bright citrus note.
• Chocolate mohn: Stir in 2 tablespoons of cocoa powder for a chocolate-poppy seed filling that’s rich and unusual.
