They were actually dead easy! I just found the screenshot I took of the recipe (conveniently cropping out whoever posted it's username). The overspiced broth was mostly smoked paprika, some mixed herbs and some light soy sauce. Then just make it into sausage shaped bits, fry lightly, wait for it to cool/dry off. Then just stick it in some pre made puff pastry and whack it in the oven at 200° for a bit.
