Churros con Chocolate

Combine water, butter, and salt in a medium heavy-bottomed saucepan over high heat. Bring to a full rolling boil, stirring until the butter is completely melted and incorporated. The entire surface should be turbulent — no butter slicks should float on top. Remove from heat the moment it hits a full boil; a moment of over-boiling evaporates too much water and throws off your flour ratio.

Tip all the flour into the boiling liquid in one go. Switch immediately to a stiff wooden spoon or silicone spatula and stir vigorously, pressing the dough against the sides of the pan. Within 60–90 seconds the mixture will pull away from the sides and form a single cohesive ball. Continue drying the dough over medium heat for another 2 minutes, stirring constantly. This step drives out excess moisture and cooks the starch so the dough can absorb eggs without becoming soupy.

Beat the eggs one at a time into the cooled panade using a hand mixer, stand mixer with a paddle, or strenuous hand-beating with a wooden spoon. After each egg the dough will look broken and slippery — keep beating until it fully absorbs before adding the next. When both eggs are incorporated the dough should be smooth, glossy, and just stiff enough to hold a piped shape. Test by lifting the spoon: the dough should fall in a slow, thick ribbon and hold a V-shape at the tip.

Heat vegetable oil to 175–180°C (350°F) in a deep saucepan or wok — use a thermometer. Pipe 15–20 cm lengths of dough directly into the hot oil using scissors or a knife to snip each rope. Fry in small batches of 3–4 without crowding, turning once with tongs after 2 minutes. Total fry time is 4–5 minutes per batch until deeply golden. The oil temperature will drop when you add dough; adjust heat to maintain 170°C. Drain on a wire rack, not paper — paper traps steam and softens the crust.

Mix the caster sugar and ground cinnamon in a wide, shallow bowl — about 10 parts sugar to 1 part cinnamon. Roll each hot churro through the mixture immediately after draining, turning to coat every ridge. The residual oil acts as a binder; if the sugar slips off, the churro has cooled too much. Work quickly. Arrange on a plate without stacking to preserve the crust.

Whisk the cornstarch into about 50 ml of the cold milk until fully dissolved — no lumps. Pour the remaining milk and sugar into a small saucepan over medium heat and warm until steaming. Add the dissolved cornstarch slurry, whisking constantly. When the mixture begins to steam and thicken, reduce heat to low and add the finely chopped dark chocolate all at once. Stir slowly until the chocolate fully melts and the sauce coats the back of a spoon thickly — this is meant to be far thicker than hot cocoa. It should mound slightly when dropped from a spoon.
