Warm the milk in a saucepan over low heat. Add the butter stirring it into the milk, so it melts. Allow to cool.
300 ml milk, 125 g butter
In a large bowl place 75 grams of the flour with the yeast, salt, orange zest and one teaspoon of the sugar. Pour in the cooled milk/butter mixture in and beat with a wooden spoon until you have a mix which resembles a thick batter. Cover with saran (plastic) wrap and a towel and leave it to rest for about half an hour.
75 g bread flour, 1 tablespoon sugar, 1 teaspoon salt, 2 orange, 7 g yeast
When you return, your mixture should be bubbling and doubled in size—place in the remaining flour, sugar, orange juice, mahlepi and eggs.
170 g sugar, 200 ml orange juice, 2 eggs, 2 teaspoon mahlepi, 750 g bread flour
Mix until a soft dough forms. If you find it's sticky, add more flour. But be careful not to add too much. We're after an elastic, silky dough. Knead for 10-15 minutes. Alternatively, you can follow these instructions using a stand mixer.
Once kneaded place in an oiled bowl and lightly oil the top of the dough. Cover with plastic wrap and a kitchen towel and allow to rest for one hour or until doubled in size. (this can take up to 3 hours depending on how warm your kitchen is).
When you notice it has doubled, take it out and divide the mixture in three equal portions. With one of the thirds, split into three equal portions again (there should be 9 balls of dough - each weighing approx. 170 grams) and roll these three portions into "ropes". They should be of the same width and length. Mine measured approximately 40cms (approx. 15 inches)
Lay down the tsoureki ropes in front of you. Join the top ends of the tsoureki with your fingers and squeeze so they stick together. Form a plait and tuck in the bottom ends so they stick together also. Complete the remaining tsourekia and place on a parchment lined baking tray and allow to proof again for 2 hours.
Once proofed and risen brush with the glaze and add any almonds or sesame seeds on the top.
1 egg yolk, flaked or slivered almonds, 1 tablespoon milk
Bake in a preheated 170 deg C fan forced / 190 deg C standard oven for 35-40 minutes until golden. They should sound hollow when tapped on the bottom. Allow cooling on a wire rack completely before slicing and serving.
