Take a glass container, pour the alcohol and add the orange peel.
Close the container and let the orange peels soak in the alcohol for 7-10 days.
Every now and then, mix in such a way that all the skins give off their aromas.
After this time, prepare the water and sugar syrup.
Pour the water into a casserole and add the sugar.
Put the saucepan on the stove and bring the water to a boil so that the sugar dissolves.
Once this is done, remove the syrup from the heat and pour it into a container to let it cool.
Filter the alcohol to remove the peels and throw them away.
When the syrup is cold, add it to the alcohol and mix … your orange liqueur is ready and all you have to do is pour it into the bottles.
