Bialys | Sponge Method

Oh, to have a freshly baked Bialy warm from the oven is one of life’s greatest joys. A mitzvah for your senses as you bite into this savory puffy disk that is delightfully crisp, soft, and chewy and gives way to the savory flavor of deeply caramelized onion and poppyseed filling that sits atop a thin crispy center layer.

The Bialy | The forgotten one. The unsung cousin to the popular bagel. Most of the world’s population has never even heard of this “Bissel” (little) round baked good. Well, it’s time to get the word out and sing the praises about this amazing crispy puffy disk of onion poppyseed filled nosh of goodness!

Bialy | is short for Bialystoker Kuchen which in Yiddish means “little bread from Bialystok” from the city of Białystok in Poland, a traditional baked good from the Polish and Polish Ashkenazi cuisine. Unlike a bagel, which is boiled before baking, a bialy is simply baked, and instead of a hole in the middle, the center of the dough gets stretched before baking to form a thin depression that supports the onion poppyseed filling with a ring of puffy dough on the outside. The Bialy is baked directly on a hot baking stone which in turn causes the ring of dough to puff up and brown and crisp quickly. This also creates a thin almost matzo like crisp center layer that supports the filling.

Kossar’s Bialys is the oldest continuous running Bialy shop since 1936 in the United States and is located in New York’s Lower Eastside at 367 Grand Street near Essex Street. A traditional Eastern European Jewish food originally sold from street carts in the old country and New York’s Lower Eastside. Kossar’s brick and mortar Bialy Shop has become a mecca for those seeking out this savory little bread.

68% Hydration = Sticky Dough | In order to create a light airy crumb with a crisp crunchy and chewy exterior, we need a dough formulation that has higher water content. Don’t be alarmed by how sticky the dough is throughout the kneading process.  “OY VEY, THIS IS A STICKY DOUGH!” Yes, it is. So don’t panic and add any extra flour. The dough will develop strength as you knead, stretch, and fold it. I promise you the end results are worth sticky fingers.

“The oven so hot I’m Schvitzing” | In order to create the best Bialys, we need to crank up the heat in our ovens. The oven and baking stone must be pre-heated to 550°F (288℃) for at least 1 hour prior to baking. The Baking Stone stores and transfers the heat to the fully proofed Bialys which creates the oven spring and quickly bakes the dough. The quick bake time keeps the moisture in the baked Bialys and produces that signature airy and chewy interior with a crisp crunchy exterior. I recommend purchasing an Old Stone Oven Rectangular Baking Stone or a Fibra-Ment-D® Baking Stone from I recently purchased a 15″ x 20″ (38 cm x 50 cm) Fibra-Ment-D® Baking Stone from which allows me to bake the entire batch of Bialys (12) or two 1.5-pound loaves of bread at the same time. They can customize their baking stones to fit the dimensions of your oven. If you do make a purchase from let them know I sent you.

What do I eat them with? | Eating a Bialy still warm from the oven is amazing, but there is nothing wrong with a healthy schmeer of butter or cream cheese with lox, red onions, capers, and tomatoes. Perfect for a breakfast sandwich or hefty slices of pastrami, corned beef, or rare roast beef. Toast or don’t toast. How you enjoy your Bialy is up to you.

As with all baking recipes I recommend you weigh the ingredients for the Bialys. Weighing ensures you have a consistent dough each and every time. As bakers, we are always striving to remove any variables from the process of baking.

      Hello Doug, It is my pleasure to meet you. Congratulations on your baking success making the bialys. I appreciate you sharing your experience. results, and thoughts with me and the Just One Bite, Please? community. Thank you for taking the time to comment. Have a great day!

    Can you please clarify two small things for me – 1) Can diastatic malt powder be used instead of the malt syrup? What would be the amount to use? 2) Can you clarify the question above about what point to place the dough in the fridge overnight? Is it after this step – “Lightly flour the work surface and place the rounded dough pieces on the floured surface, cover with plastic wrap, and let dough pieces rest for 30 minutes.” Your comment above mentions Step 4 – which there are several!

    Your videos, instructions, etc are extremely detailed and well appreciated. I did a sample batch of these bialies and they are fantastic! Think I’ll make a double batch tomorrow!

      Hello Nathan,

      The recipe uses non-diastatic barley malt syrup for flavor, color development, and food for the yeast. Using diastatic malt powder will cause the dough to ferment quickly and weaken the dough structure if switched out for the barley malt syrup. I would recommend using honey if you cannot find barley malt syrup.

      It is in Step 4 of “Dividing, Preshaping, Final Shaping, Filling and Baking the Bialys” that you can refrigerate the dough overnight with good results. I would recommend picking up where you left off with the next steps with the dough directly from the refrigerator.

      Thank you for taking the time to write and ask your questions and share your thoughts with me and the Just One Bite, Please? community.

      Have a wonderful holiday season and Happy New Year!
