After the beans have soaked for long enough, rinse them and place in a saucepan, add enough water to cover them
Bring water to a boil over medium heat and once boiling darin the beans, add fresh water and bring it to boild again
Once boiling leave the beans to simmer for 1 hour, keep an eye on them an top up with water when needed
Beans are done when you can easily squish them in between your fingers
When the beans are done, reserve some water and put the beans into a food processor with 35 grams of sugar (add water when processing if it looks too thick, it should look like a smooth paste)
Put the paste back into a dry saucepan and put it on medium heat to reduce liquid, take it out and place it into a container where the paste will continue to thicken a bit more as it cools down
Start making the dough by placing 30 ml of water into a saucepan over low medium heat, stir in bread flour and mix until it's a runny paste
Slowly pour in 30 ml of milk and whisk everything until it thickens up like a pudding then take it off the heat
Place the mixture into a container and cover it with cling film to allow to cool down to room temperature
In a seperate bowl mix lukewarm milk (65 ml), 1 tsp of sugar and yeast
