Jammy Strawberry & Brown Butter Sablé Slab

Instructions

1. 1

   Melt 1 cup unsalted cultured butter in a saucepan over medium heat. It will foam, then crackle. Swirl the pan until the milk solids drop to the bottom and turn the color of a wet penny. You are making beurre noisette (brown butter), the backbone of this dessert. Pour it immediately into a wide metal bowl to stop the cooking.

   8 min

   Tip: Butter is not a garnish; treat it with respect. Don't walk away while it browns.

2. 2

   Place the metal bowl in the freezer. You want the butter to become opaque and set to the texture of soft lip balm. Cami's shortcut note: The freezer trick takes this from a two-hour wait to a 15-minute pause.

   15 min

   Tip: Keep an eye on it. You want soft room-temperature consistency, not a frozen brick.

3. 3

   While the butter chills, toss 1 lb fresh strawberries with 1/4 cup granulated sugar and 1 tbsp lemon zest in a bowl. Let them sit so they release their water.

   10 min

   Tip: Why it works: Sugar draws out moisture via osmosis. Water is the enemy of a crisp crust, so we extract it before baking.

4. 4

   Heat your oven to 350°F (175°C). Line a 9x13-inch quarter sheet pan with parchment paper, leaving a slight overhang on the edges so you can lift the slab out later.

   5 min

5. 5

   Take your chilled, opaque brown butter and beat in 3/4 cup powdered sugar until creamy. Add 2 large egg yolks and 1 tsp vanilla extract. Mix just until incorporated. Fold in 2 cups all-purpose flour, 1/2 cup almond flour, and 1 tsp flaky sea salt. The dough will look sandy (sablé literally means sandy). Don't overwork it or the crumb gets tight like a bad alibi.

   5 min

   Tip: A wooden spoon or a spatula works perfectly here. No mixer needed.

6. 6

   Dump the dough into your lined pan. Use the flat bottom of a measuring cup to press it firmly into an even layer.

   5 min

   Tip: Press firmly to ensure a solid base that won't crumble when cut.

7. 7

   Use a slotted spoon to scatter the macerated strawberries evenly over the dough. Don't skip this: Leave the accumulated red liquid in the bowl (drink it later with sparkling water). Press the berries gently into the crust.

   2 min

8. 8

   Bake for 35 to 40 minutes. Look for visual cues: the exposed edges of the crust should be deeply golden and the strawberries should look collapsed, matte, and jammy.

   40 min

   Tip: If your oven runs hot, rotate the pan halfway through.

9. 9

   Let it cool completely in the pan. If you try to cut it warm, it will shatter into a tragic, delicious mess. Let time do the work. Once cooled, use the parchment overhang to lift it out, then use a sharp chef's knife to slice into elegant fingers.

   60 min

   Tip: Wipe your knife between cuts for sharp, café-level edges.
