Pour the lukewarm water into a large bowl.
Add yeast and mix with a fork until dissolved.
Top with the yogurt and maple syrup, followed by the egg, salt, and melted butter.
Add the flour bit by bit, kneading in between (you want a slightly sticky dough).
Knead by hand or using a mixer until smooth.
Cover the dough. Let it rise for 1 hour.
Roll the dough out on a floured surface. Roll it into a circle (about 1 cm (¼ inch thick).
Cut into 12 symmetrical slices.
Divide the four sausages into 12 pieces, and top the widest outer section of dough with a piece of sausage.
Tuck in the sides and roll like a croissant.
Shape the sausage rolls into a heart on a lined baking sheet (or space them out).
Cover and let the rolls rise again for 30 minutes.
Preheat the oven to 180°C (356℉).
Brush the sausage rolls with egg wash or milk.
Bake for 15 minutes until golden brown.
