Serradura Recipe

Prepare biscuits

Place the 200 g of plain tea biscuits in a large zip-top bag or food processor. Crush to fine crumbs — aim for a sand-like texture with a few slightly larger pieces for texture. If using a bag, use a rolling pin and work in bursts until uniform.

Melt the 80 g unsalted butter in a small saucepan over low heat or in short bursts in the microwave until fully liquid. Allow to cool slightly but keep pourable.

Combine the biscuit crumbs and melted butter in a bowl and mix until the crumbs are evenly coated and hold together when pressed. Reserve about 30 g of the crumb mixture (or the separate 30 g extra crushed biscuits from the garnish section) for final dusting.

Press about two-thirds of the remaining buttered crumbs into the bottom of an 8x8-inch (20x20 cm) square baking dish or into individual serving glasses/ramekins to form an even base layer about 1–1.5 cm thick. Press firmly with the back of a spoon or the base of a measuring cup. Chill in the refrigerator while you make the cream layer, about 10–15 minutes.

If using cream cheese (100 g) for a firmer set: soften it at room temperature for 15–20 minutes and beat in a bowl until smooth with the 1 tsp vanilla and a pinch of fine sea salt before proceeding to fold with whipped cream and condensed milk.

Pour the 400 g sweetened condensed milk into a medium bowl. If you used cream cheese, add the sweetened condensed milk to the beaten cream cheese and whisk until homogeneous.

Using a chilled bowl and whisk or electric mixer with whisk attachment, whip the 300 ml cold heavy cream to soft peaks. Do not overwhip — the cream should hold soft peaks but still be pliable.

Gently fold about one-third of the whipped cream into the condensed-milk (or condensed-milk + cream cheese) mixture to lighten it, then fold in the remainder with a spatula until fully combined. Add a pinch of salt and the 1 tsp vanilla extract during folding. The resulting mixture should be smooth, thick, and spreadable.

Spoon or pipe a thick layer (about half of the cream mixture) over the chilled biscuit base and smooth the top with an offset spatula or the back of a spoon. Sprinkle a thin, even layer of reserved crushed biscuits over the cream for the traditional sawdust appearance.

Repeat with another thin layer of pressed biscuit crumbs (use remaining biscuit mixture) if you want multiple alternating layers: press lightly, then top with the remaining cream mixture and smooth.

Finish with the reserved 30 g extra crushed biscuits dusted evenly on top to create the serradura 'sawdust' effect.

Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to allow the cream to set and flavors to meld. If you used cream cheese, 3–4 hours is sufficient; without cream cheese, overnight gives the best texture.

About 10–15 minutes before serving, remove the serradura from the refrigerator to take the chill off slightly (it should still be cold and sliceable).

If desired, dust the top lightly with cocoa powder or sprinkle chocolate shavings for extra flavor and contrast.

Decorate with fresh berries or mint leaves as desired. For individual glasses, layer crumbs and cream alternately and finish with crumbs and a berry on top.

Serve cold with a spoon. Store covered in the refrigerator for up to 3–4 days; the biscuit layers will continue to soften over time.
