The Orthodox Church has posted a manual for painting Easter eggs on Maundy Thursday.

PAINTING EASTER EGGS

MAINTAINED THURSDAY – we paint some of the Easter eggs red. We paint one for each family member and a few close people, as well as one egg for the house, which we keep inside the house for 1 year, until the next Easter.
On MAD SATURDAY – we dye Easter eggs red again. We dye as many as we want, i.e. we dye for our family's consumption and we also dye to give to others.
INGREDIENTS needed:
* Food coloring for eggs (found in the church)
* 25-30 eggs (can be made even less, if desired)
* 6 cups lukewarm water
* 1 and a half cups of good quality black vinegar
* A napkin coated with sunflower/olive oil (optional)

PREPARATION

– FIGURE 1 – Wash the eggs you want to dye well and boil them over low heat so they don't run.
– FIGURE 2 – In a container, pour 6 cups of lukewarm water, the vinegar in the cup, the paint, and mix very well.
– FIGURE 2 – Place the well-boiled eggs (approximately 15 eggs) in the container with the dissolved dye and leave them in for 3-5 minutes.
– FIGURE 3 – Next, remove them and let them dry.
– FIGURE 2 – Place the other 15 grains in the same paint.
– FIGURE 4 – Finally, brush them with an oiled napkin to make them shine.
– This can be done as desired if you want to make more eggs.

THE MEANING OF THE TRADITION OF DYEING EGGS
The egg symbolizes life, which is closed and dormant within its shell, which comes to light when it breaks. The red color of eggs symbolizes sacrifice and in this case symbolizes the sacrifice of Christ, a symbol of victory, joy and life. Thus, the egg shell symbolizes the tomb of Christ, which was opened and gave life.
There is also a Church legend about the red egg: When Mary Magdalene, after the resurrection of Christ, went to Pilate to inform him of the event and brought him a basket of white eggs as a gift, according to the custom of that time, he said to her: As much as the eggs you brought can turn red, so much can Christ be resurrected. And surprisingly, the eggs immediately turned red.
