The night before you want the buns, mix all the ingredients together in a big bowl and cover with cling film. Pop the bowl in the fridge and let it sit there overnight.
In the morning, remove the dough from the fridge and gently scrape it out of the bowl onto a floury surface. Divide it into 16 pieces. Flour your hands and shape each piece into bun. Use a scraper to place each bun on a baking tray lined with parchment paper.
Cover and let rise for one hour.
Heat the oven to 220 degrees C and pop the buns in when it's up to temperature.
Bake for 20 minutes and then remove them and place them on a wire rack to cool.
Enjoy them in the company of strangers in need.
