Begin by preheating your oven to a temperature of 425 F. To make the filling for your Eccles cakes, take a medium-sized saucepan and combine 110 grams of sugar with 25 grams of butter. Cook this mixture over medium heat until the butter has melted completely.
Once melted, remove the saucepan from the heat and add in the currants, candied fruit peel, and nutmeg. Set the mixture aside to cool. Meanwhile, on a surface that has been lightly dusted with flour, roll out your pastry to a thickness of 1/4 inch.
Using a wide glass or a large cookie cutter, cut the pastry into 10 rounds that measure 4 inches each. Lightly grease a baking sheet with the remaining butter and place the rounds on the sheet. Add a small spoonful of the filling to the center of each round.
To seal the cakes, dampen the edges of the pastry with cold water and bring the edges together over the fruit. Pinch the edges to create a seal. Turn the cakes over and use a rolling pin to gently flatten them if necessary.
Use cooking scissors to snip a V shape on top of each cake, or if you prefer a more traditional look, cut three slits instead. This will help steam escape during the baking process. Brush the cakes with cold water and sprinkle the remaining sugar over them.
Place the baking sheet in the center of your preheated oven and bake for 15 minutes. Keep an eye on the cakes and remove them from the oven when the edges are lightly golden brown.
Finally, place the Eccles cakes on a wire cooling rack to cool down. Enjoy your homemade treats!
