Lovely recipe! Very different from anything else I've eaten that involved a biscuit dough, I doubled this recipe so I could gift it to a few people and they all loved it. For the vegan butter, I used a 50/50 mix of Tesco's own 'Baking Block' and Crisp n Dry (I normally use Trex but this worked just as well. I didn't need the full 5 teaspoons of vegan milk, just a couple to bring the dough together.
