This recipe makes about 40 biscuits, I know that's a lot but they do keep for about 4 weeks. Look out for more doggie treats how to's soon!
200ml(6 fl oz) hot water
200g(7 oz) polenta
50g(2 oz) tripe, finely chopped
Pour the hot water over the polenta, stir and let cool. Then knead in the other ingredients.
Preheat the oven to 180 degrees (350 Fahrenheit). Line a baking sheet with baking paper.
On a floured surface, roll out the dough to about 1cm(1/2 inch) thick and cut it into triangles. Place these on the baking sheet and bake for 25 minutes. Turn off the heat and let biscuits dry for a few hours in the oven. Store in a screw-topped glass jar or biscuit tin.
