First, slit the vanilla pod lengthwise and scrape out the pulp, coarsely chop the almonds.
Peel the pears, cut them into pieces and place them in a large, light glass (the sugar syrup must also have room later). Sprinkle vanilla pulp and almonds, put spices on top.
Pour the liquor, close the jar tightly and put the mixture in a sunny place for 10 days. Shake daily.
Bring 1 l of water to a boil with the sugar and boil to a syrup. Allow to cool and pour into the pear liqueur mixture. Leave to infuse for another 10 days, shaking frequently during this time.
Hang a strainer in a pot and line with filter pa pier or muslin cloth. Filter the liqueur and decant it into carefully cleaned bottles.
Close immediately and store the pear liqueur in a dry and dark place.
