Yesterday I made some biscuits for Ruby. At lunch she either has one of these and a very thin strand of dried tripe, or one fat piece of dried strip, or a vegetable based chew.
I adapt Rhonda Hetzel's recipe for these a lot of the time, see here. I have used others. If I use stock stead of water, I don’t add the cheese, sometimes as stock I use a teaspoon of peanut butter in hot water, left to go cold.
Herewith the 1/2 size recipe I used yesterday:
1 cup water.
1 cup oat flour made by whizzing up oats
1/2 cup wholemeal flour
1/2 cup rolled jumbo or normal oats
1/4 cup powdered milk
1 Tablespoon whole Linseeds
1 Tablespoon whole Chia seeds
1" piece of cheddar grated
1/2 clove finely chopped fresh garlic - optional depending on how you feel about it!
Don't add all the water to begin with as oat flour gets very sticky. Add more flour if needed.
Roll out to the thickness of a coin, stamp or cut out shapes and bake at 160 -170C for 1 hour.
Leave to dry in the cooling oven with the door slightly ajar or finish off in a dehydrator to thoroughly crisp up.
If I have used the leftover dough from the biscuits, to make small training treats, I break them up into individual ones (from the long strip seen below). This helps them thoroughly dry.
