In a large mixing bowl, combine the bread flour, salt, sugar, and dried yeast. Stir them together so the yeast is evenly spread.
Make a well in the center and pour in the melted butter, beaten eggs, and tepid milk. Mix everything together using a wooden spoon or your hands until a soft dough forms.
Turn the dough out onto a floured surface. Knead it for about 8-10 minutes, until it becomes smooth and elastic. If the dough feels sticky, sprinkle a little more flour as you knead.
Flatten the dough slightly and sprinkle over the golden raisins and chopped candied peel. Fold the dough over the fruit and knead gently a few more times to evenly distribute them without squashing the fruit.
Place the dough in a clean, lightly oiled bowl. Cover it with a clean tea towel or plastic wrap, and leave it to rise in a warm place for about 1 to 1½ hours, or until it has doubled in size.
Once risen, punch the dough down gently to release air. Divide the dough into 12 equal pieces and shape each into a round bun.
Arrange the buns on a baking tray lined with parchment paper, leaving space between each bun to rise again. Cover and let them rest for another 30-40 minutes until puffy.
Preheat your oven to 375°F (190°C).
Brush the tops of the buns with the beaten egg glaze, then sprinkle with nibbed sugar or crushed sugar cubes to give them a lovely crunchy topping.
Bake the buns for 15-18 minutes, or until they are golden brown and sound hollow when tapped underneath.
Remove from the oven and cool slightly on a wire rack before serving.
