500ml flour (white or whole meal or even a mixture of both)
1 tsp bouillon powder
125ml hot water
2 tbs Parmesan
1 tbsp marmite
Dissolve bouillon in water, then stir the marmite in until dissolved
Whisk egg into the bouillon/marmite mix
Measure out flour and add the grated parmesan cheese
Mix wet and dry ingredients together into a dough
Roll dough out onto a floured surface and cut into desired shapes. I used a cute bone shaped cookie cutter which was 3D printed for me by the lovely Ronel Pieterse from All Sorts 3D Prints
Bake for 30 mins at 150 degrees.
