Preheat oven to 180C/350F.
Add melted butter and diced garlic together and use a pastry brush to grease the muffin holes with the garlic butter. Set aside.
Mix the sourdough starter, eggs, milk and oil in a bowl. Whisk together until well combined.
In a separate bowl mix together shredded cheese, all purpose flour, salt, baking powder, salt and chopped herbs. Make sure that the cheese is completely coated in flour.
Now pour the liquid ingredient mixture into the dry ingredients. Gently fold together until just mixed - don't over mix or the muffins will be tough.
Spoon mixture into greased muffin holes.
Bake at 180C/350F for approximately 30 minutes or until muffins are golden brown.
Allow the muffins to cool on a rack for around 15 minutes before enjoying them. They are delicious warm or cold.
