1. Chop the orange peel finely and mix it with the herbs and alcohol. Let it stand for 15-20 days in a sealed jar, agitating it every day.

2. Pour off spirits through a cloth, and seal again.

3. Put the strained off seeds and peel in a saucepan, crush it, cover with boiling water and simmer for 5 minutes. Pour into another jar, cover and let stand for 2 days. Strain this off and add it to the spirits. Add caramel coloring, filter again and let it rest until it settles perfectly clear.
