Poppyseed Stollen (Mohn Stollen)

Ingredients

• For the Fondant (sugar glaze)
• 1 1/2 cups water
• 1/2 teaspoon cream of tartar
• 4 1/2 cups white sugar 
• 2 tablespoons lemon juice
•  
• For the Sponge:
• 3/4 cup milk, room temperature, divided
• 1 1/2 (0.6 ounce) cakes cake yeast
• 1 teaspoon white sugar
• 1 cup unbleached flour
•  
• For the Dough:
• 3 cups unbleached flour
• 1/4 cup white sugar
• 1 pinch salt
• 2 eggs, room temperature
• zest from 1 lemon
• 3/4 cup unsalted butter, room temperature and cut into chunks
• 1/2 cup ground almonds
•  
• For the Filling:
• 3/4 cup milk
• 3 tablespoons unsalted butter, at room temperature
• 1/3 cup white sugar
• 2 1/2 cups poppy seeds
• 1 1/2 teaspoons lemon zest
• 1/2 teaspoon ground cinnamon
• 1 egg, room temperature

Directions

1.                    First, make the fondant. It needs to be refrigerated overnight before using. To make the fondant, you'll need a marble slab or a baking sheet and an offset spatula to fold the candy. If you're using a baking sheet, rinse it with water, leaving a few drops on the pan.

2.                    Dissolve the cream of tarter in the water in a heavy-bottomed saucepan. Add the sugar and bring the mixture to a boil over medium-high heat. Swirl the pan occasionally to help dissolve the sugar. Do not stir once the sugar syrup begins to boil. Heat to 240 degrees F, or until a small amount of syrup dropped into cold water forms a soft ball that flattens when removed from the water and placed on a flat surface.

3.                    Immediately pour the candy onto the baking sheet or marble slab and let cool for 10 minutes. Use a spatula to vigorously knead the candy, folding it over itself. Knead until it begins to look cloudy, 5 to 10 minutes; allow it to cool. Transfer the fondant to a heatproof bowl or the top of a double boiler. Refrigerate overnight.

4.                    To make the sponge, dissolve the yeast and 1 teaspoon sugar in 1/4 cup of the room-temperature milk. Pour the remaining 1/2 cup milk into the bowl of a stand mixer. Add 1 cup of flour and the yeast mixture. Mix with a fork to combine. Cover the bowl with a towel and allow to rest until bubbly, 10 to 15 minutes.

5.                    Stir the remaining 3 cups of flour, 1/4 cup sugar, salt, room-temperature eggs, and zest from 1 lemon into the sponge. Use the dough hook to mix the dough on the lowest setting. Mix the dough for about 5 minutes, occasionally scraping the dough off of the hook and down the sides of the bowl.

6.                    Increase the speed to medium-low and add the softened butter 1 tablespoon at a time until fully incorporated. Allow the dough to mix for an additional 5 minutes, scraping the dough down as needed. Add the ground almonds and turn the mixer on for 1 or 2 turns, mixing just until incorporated. Transfer the dough to a lightly floured work surface and shape it into a ball. Place the ball in an oiled mixing bowl and cover with plastic wrap and a kitchen towel and let it rise until doubled, 1 1/2 to 2 hours.

7.                    While the dough is rising, prepare the filling. Heat the milk in a heavy 4-quart saucepan until it begins to boil; stir in the butter and sugar. Remove the pan from the heat and add the poppyseeds, 1 1/2 teaspoons of lemon zest, and the cinnamon. Let the mixture stand for 30 minutes to soften the poppyseeds. When the mixture is cool, whisk in the egg.

8.                    Punch down the dough and roll it out into a 10 1/2- by 16-inch rectangle. Spread the filling evenly over the dough, leaving a 1-inch margin on all sides. Roll the dough up into a log, starting with the long side, and pinch the edges together to form a seam. Place the loaf, seam-side down, on a parchment-lined baking sheet. Cover it with greased plastic wrap or a well-floured kitchen towel and allow it to rise for an additional 30 to 40 minutes.

9.                    Preheat an oven to 400 degrees F.

10.                 Bake the stollen until golden brown on the bottom of the loaf, about 40 minutes. Let the bread cool completely before glazing.

11.                 To glaze the bread, add the lemon juice to the fondant. Place the bowl over a pan of simmering water, stirring frequently with a rubber spatula until soft and glossy. Pour the fondant over the stollen and allow it to cool before slicing.

Footnotes

• Cook's Note:
• You will need about half a pound of poppyseeds for the filling (2 1/2 cups).
• Editor's Notes:
• Making fondant uses a technique similar to tempering chocolate: crystals develop as you fold it over itself while it cools. You'll need an offset spatula or a putty knife to knead the fondant. Reheat fondant in a double boiler just until fluid; if it gets too hot, it will lose its lustrous shine. If you'd rather skip the fondant topping, you can brush the stollen with melted butter and roll it in powdered sugar to coat it instead.
• You may substitute 1 1/2 envelopes (3 1/2 teaspoons) of active dry yeast in place of the cake yeast. Proof dry yeast in the milk before mixing the sponge.

Notes from Helga:  This is another recipe that was posted on an internet site.  I remember Mom serving this a few times for special guests.  It goes well with coffee and cream.  At my tender young age, my taste buds were a bit overwhelmed by the large amount of poppyseeds.  They are definitely an acquired taste.  Clearly, this recipe is labor intensive as well.
