• Position the oven rack in the middle of the oven, and preheat it to 350° F / 177° C (160° C fan).
• Lightly grease an 8-inch square or round baking pan with butter or baking spray and line it with parchment paper.

Make the dough

• Combine flour, white granulated sugar,baking powder and salt in a large bowl then add the butter.
• Use your fingertips or a fork to mix the butter into the flour mixture.
• Pour in the milk and use a spatula or hands to form a soft dough.
• Turn out onto a well-floured surface and shape the dough with your hands to form approximately an 8x12 inch (20x30cm) rectangle. Avoid using a rolling pin (see note 2)

Filling

• Spread store bought or homemade lemon curd on top of the dough in an even layer.
• Sprinkle the raisins or cranberries (if using) Feel free to omit them if you don't like raisins or cranberries

Shape

• Starting with the longer edge, gently roll the dough into a long and tight roll.
• Cut the roll into 9 pieces, each about 1½ inches (4cm) thick. Carefully transfer them to the baking sheet and gently press them down a little.

Bake

• Bake for 15 minutes, then turn the baking sheet around in the oven and bake for a further 10 to 15 minutes until golden brown.
• After taking the buns out of the oven, leave them in the pan and cover it for about 10 minutes with plastic wrap, aluminum foil, or a clean cloth to trap steam and maintain their softness.

Make the glace icing

• Add powdered sugar and hot water or milk in a small bowl.
• Whisk until thick and smooth.
• Uncover the buns, and while they're still warm, spread or drizzle some glace icing on each bun. The slight warmth helps the glaze soak into the buns, making them tastier and softer
• Finish by adding a whole or half candied cherry on top of each bun.
• Serve plain, sliced and buttered or with a spread of extra lemon curd

Storage

• At room temperature: For up to 1 day in an airtight container
• Refrigerate: For up to three days in an airtight container.

Reheating

• These rolls are best enjoyed warm whether stored at room temperature or refrigerated
• Use the microwave or air fryer to reheat or warm (which also softens during reheating) You can reheat the rolls with the glace icing without the risk of it melting off.
• Microwave: Place the rolls on a microwave safe plate. Cover with a moist paper towel. Reheat for 20-25 seconds increments until warmed through.
• Air fryer: Preheat the air fryer to 350°F. Place rolls in a parchment paper liner and place in the air fryer basket and close the door.

  Alternatively, wrap them in aluminum foil instead of using parchment paper. Using the "reheat" setting, reheat them at 350°F (180°C) for 2 minutes.
