In a small bowl mix together the lukewarm water, milk, yeast and sugar. Set the mixture aside until it froths. This usually takes about 15 minutes.
In a mixer or in a large bowl, mix the flour, salt and garlic powder together and make a well. Add the olive oil and the yeast mixture in the well.
Start kneading or mixing the dough in the mixer. If you are going to knead the dough by hand it should take you about 20 minutes. Whereas with the mixer, the dough should be done in 10 minutes. The dough should be sticky, so don’t add any extra flour to it.
Place the dough in a bowl, cover and let it proof for about 1 hour. After this resting time, it should be double in size.
Preheat the oven to 200°C or 400°F. Line a baking tray with parchment paper. Set aside.
Once rested, punch the dough down on a lightly floured surface. Divide into 16 pieces. Roll each piece into a 10cm rope and tie into a knot.
Place on the baking tray. Cover and let rest for 30 minutes.
Brush the knots with some milk and bake for about 20 minutes until they have a nice golden brown colour.
In a small bowl, whisk together the melted butter, minced garlic, oregano, parsley, mint and salt; set aside.
Once ready, brush each knot with the garlic butter mixture and sprinkle grated parmesan on top.
