1. Pour the cordial into a bowl and dissolve the yeast into the water. Once bubbles start to appear on the surface of the mixture, pour in about a third of the flour, followed by the two eggs, the rest of the sugar, the salt and the sunflower oil.
2. Get your hands into the dough and combine the mixture, adding flour little by little as you go, until you get a big ball of dough which doesn’t stick to your hands (you might not need all the flour – just see what your dough needs). Sprinkle a clean work surface with flour and knead the dough for five to 10 minutes, adding a bit of flour if it gets too sticky again.
3. Place the dough in a lightly oiled bowl covered in cling film to rise for about an hour and a half or until it has doubled in size.
4. Once the elderflower challah dough has risen, knock it back and place on a lightly floured surface to shape. Please take a look at the photo of the Challah Mummy Elderflower Challah for shaping inspiration.
5. Once shaped, leave the elderflower challah dough to rise again under a clean cloth or cling film.
6. Once risen again, egg wash the elderflower challah dough using egg white and then bake in the oven at 180 degrees Celsius (350 degrees Fahrenheit) for 25-30 minutes at the bottom of the oven.
