Maison Aleph’s Sesame-Halvah 1,001 Feuilles

Preparation

1. Step 1

   Make the filling: Working with a mixer (preferably fitted with a paddle attachment), beat the butter, halvah and tahini together on medium speed for about 3 minutes. Add the confectioners’ sugar, cornstarch and salt, and mix on low for 2 minutes more. Add the eggs one by one, beating for a minute after each goes in; you’ll have a thick, smooth, shiny mixture (think mayonnaise). Stir in the sesame seeds. Scrape the filling into a bowl, cover and refrigerate for 1 hour (or for up to 2 days; longer is better than shorter).

2. Step 2

   Build the layers: Lay the phyllo out on a piece of plastic wrap, and cover with a damp kitchen towel. Always keep the towel moistened: The dough dries in a flash.

3. Step 3

   Brush the interior of a rimmed baking sheet (12 inches by 17 inches) with clarified butter. Place a sheet of dough in the pan, brush with butter and dust lightly with confectioners’ sugar (use about 2 tablespoons of sugar per sheet). Continue until you have made 14 layers. Spread the filling evenly over the top, and then continue making layers with the remaining dough, buttering and sugaring each layer (you’ll have some butter left; hold on to it). Refrigerate the setup for at least 30 minutes (or cover and refrigerate for up to 1 day).

4. Step 4

   Center a rack in the oven, and heat it to 350 degrees. Using a pizza cutter (best) or a sharp knife, trim the edges (don’t remove them), then cut as many 2-inch squares as possible, cutting all the way through the layers. Scatter the sesame seeds over the top.

5. Step 5

   Bake for about 40 minutes, rotating the pan after 20 minutes, until the top is beautifully golden. Transfer to a cooling rack, and lightly brush with some of the reserved butter. Place a piece of parchment or foil over the surface, top with another baking pan and press evenly and firmly to compact the layers. Recut the squares, so they’ll be easy to lift out. Let sit for 2 to 3 hours before serving (discard or nibble the trimmed edges). Stored tightly covered, the squares will keep at room temperature for about 2 days.
