STEP 1/5
Put all ingredients except biscuit ingredients, raisins, and walnut bonsai into the baking machine and knead them, then add raisins and walnut bonsai at the end of the dough and finish the first fermentation. If you put raisins and walnut bonsai in from the beginning, it's all crushed.
STEP 2/5
Gently beat butter at room temperature and mix sugar little by little while the dough is fermenting. Dissolve coffee in lightly heated milk, mix little by little in butter, add the powder sifted and complete the dough.
STEP 5/5
Divide the biscuit dough and roll it with a rolling pin, and after medium fermentation, place and wrap the dough formed into a rugby ball shape. Place the biscuit-wrapped dough in a pan, let it ferment for 45 minutes to 1 hour until it doubles, and bake in an oven preheated to 180 degrees for 20-25 minutes.
