In a large mixing bowl, combine 420g flour, sugar, yeast and salt.
In a separate jug, mix the plant milk, rapeseed oil, vanilla extract and orange zest.
Add the Tangzhong and wet ingredients to the dry ingredients.
Mix until combined, then knead the dough on a floured surface for about 8-10 minutes, until smooth and elastic.
Gently knead in the raisins and flaked almonds until evenly distributed.
Place the dough in a greased bowl, cover and let it rise in a warm place for about 1 hour or until it has doubled in size.
