The prickly pears are peeled - cut off the top and bottom, score the slightly leathery peel and then peel off in one piece. Cut the pulp into small cubes.
Pour the alcohol on the prickly pear cubes. Add water, sugar and vanilla pod and shake vigorously until the sugar is completely dissolved. Then let it stand for several weeks until the pieces of pulp gradually lose their color. During this time you should shake or stir the liqueur more often.
