In a large bowl, thoroughly mix the flour, currants, baking powder, mixed spice, salt, and 75 grams of caster sugar. Rub in the vegan margarine until the mixture has a breadcrumb-like consistency.
Gradually pour in the almond milk and mix until a dough forms.
Tip onto a floured surface and roll to the thickness of your little finger, then cut into 5-cm discs.
Warm a lightly oiled, heavy-based pan over medium heat and fry the cakes until golden on each side.
Remove from the pan and sprinkle with caster sugar.
