In blender, sprinkle unflavored gelatine over cold milk; let stand 2 minutes. Add boiling water and process at low speed until gelatine is completely dissolved, about 2 minutes. Add strawberries and sugar; process at high speed until smooth. Pour into 8 (5 oz) paper cups (or you can use plastic popsicle molds) until partially frozen, about 1 hour. Insert wooden ice cream sticks; freeze until firm, about 4 hours. To serve, let stand at room temp. 2 minutes; tear away cup.
