Prepare the Dough:
Combine the warm milk and sugar in a large mixing bowl. Sprinkle the yeast over the mixture and let it sit for 5-10 minutes until foamy.
Add the melted butter and eggs to the yeast mixture and whisk until well combined.
In another bowl, sift together the flour and salt. Gradually add this dry mixture to the wet ingredients, stirring until a dough forms.
Turn the dough onto a floured surface and knead for about 8-10 minutes until smooth and elastic or mix it for the same length in a stand mixer.
Place the dough in a greased bowl, cover it with a clean kitchen towel, and let it rise in a warm, draft-free place for about 1-1.5 hours or until doubled in size.
Prepare the Filling:
Combine the chopped candied ginger, toasted nuts, and orange zest in a small bowl. Set aside. (Note: if you’re unable to find candied ginger, you can use 2 to 3 tablespoons of fresh ginger)
Form the Buns:
Once the dough has doubled, punch it down to release the air. Turn it out onto a lightly floured surface.
Flatten the dough into a rectangle and sprinkle the filling evenly over the surface.
Roll the dough into a log and cut it into 12 equal pieces. Shape each piece into a smooth ball and place them on a parchment-lined baking sheet, leaving some space between each bun.
Cover the buns with a kitchen towel and let them rise again for 30-45 minutes or until puffy.
Preheat the Oven:
While the buns rise, preheat your oven to 375°F (190°C).
Make the Crosses:
Mix the flour and water in a small bowl to form a thick paste. Transfer the paste to a piping bag fitted with a small round tip.
Pipe crosses onto the tops of the risen buns.
Bake the Buns:
Place the baking sheet in the preheated oven and bake the buns for 15-20 minutes or until golden brown and cooked through.
Remove the buns from the oven and transfer them to a wire rack to cool slightly.
Glaze the Buns:
Heat the guava jam and water over medium heat in a small saucepan until melted and smooth. (Note: you can use apricot jam or guava paste if you’re not able to find guava jam)
Brush the warm glaze over the tops of the buns.
Serve and Enjoy:
Serve the hot cross buns warm or at room temperature. In every bite, enjoy the delightful combination of candied ginger and toasted nuts!
Storage:
These hot cross buns are best enjoyed fresh on the day they are made. However, you can store any leftovers in an airtight container at room temperature for up to 2 days. If desired, warm them slightly before serving.
