Wash apples thoroughly and grate dry. Remove apple stalks and stick wooden stalks halfway into the apples in the same place. Dissolve sugar in 110 ml water in a pot at low heat. Add butter and syrup and bring to the boil. Continue cooking without stirring until the toffee has reached 170°C (use sugar thermometer)
Take the pot from the stove and stir in the nuts. Carefully dip the apples individually into the mixture so that they are completely covered. Put them on baking paper and let them get firm
