In a microwave-safe jug/bowl, pour in the water, milk and stir in a teaspoon of sugar. Place the jug into the microwave and zap it for 30 seconds. Stir the mixture and place a thermometer in. The water should be lukewarm in temperature and read between 36.5 to 40.5 C (100 to 110 F). You may need to leave the milk mixture to cool for a few minutes if it's too hot. Once it reaches the correct temperature, stir in the yeast. Cover and leave for 7 minutes or until foamy. If it doesn't foam, your yeast is no longer alive, so discard the mixture.
In the bowl of a stand mixer, place in the flour, sugar, cinnamon, nutmeg, ginger, cloves and salt and give it a quick whisk. Place the butter into the flour mixture and mix it at low speed using the paddle attachment until the flour resembles breadcrumbs.
Switch the paddle attachment of the stand mixer to a dough hook. Give the foamy yeast mixture a quick stir, then pour it over the flour mixture along with the egg. Run the mixer on medium-low until it forms a dough and it leaves the sides of the bowl. Scrape the sides and base of the bowl with a spatula occasionally.
Add in the dried mixed fruit to the batter. Continue to knead the dough at a medium-low speed for 10 minutes.
Spray/brush a large bowl lightly with oil and place the dough in, then spray more oil over the top surface of the dough to prevent it from drying out. Cover the bowl with cling wrap/plastic film and cloth for 2 to 3 hours or until dough has doubled in size. The warmer the kitchen is, the faster the dough will rise.
Line 2 large baking tray with non-stick baking/parchment paper. Weigh the dough and divide it by 16. Mine was approximately 70gm (2.5oz) for each bun. Lightly flour clean work bench, then shape the dough into a long log. Cut the dough roughly into 16 sections and weigh one so they'll be roughly the same size.
Flatten a piece of dough, then lift the edges and press it towards the centre. You will get a rough-looking ball. Turn the dough over and cup it with your hand and roll the dough against the kitchen bench until you get a smooth ball. Repeat process with the remaining dough. You may need dust more flour if the dough becomes tacky.
Place the dough balls on the baking tray and space them out. Lightly spray the top surface of the dough with oil and loosely cover them with cling wrap. Let the dough rest for an hour.
In the last 15 minutes of the dough rising time, preheat oven to 200°C (390°F) or 180°C (360°F) for fan-forced ovens. For the cross - In a bowl, mix the flour and 4 tbsps of water together, then drizzle in the last tablespoon of water in whilst mixing. You may not need to use all the water, depending on the consistency. The paste should be runny enough to pipe but hold its shape. Place the paste into a piping bag or snap lock bag. Cut off the tip of the piping bag or snip the corner of the snap lock bag to create a piping nozzle. Pipe the crosses on each bun, then bake in the oven for 12 to 15 minutes until the tops have browned. Whilst baking, make the glaze by placing jam and water in a small microwave-safe bowl and zap for 20 seconds, then mix to combine.
Remove the hot cross buns from the tray and place them on a cooling rack. Brush each bun with the glaze whilst the buns are still hot. Leave the buns to cool completely before serving or they will taste doughy. They taste the best when served on the day.
