In a saucepan, place the water, sugar and Port wine. On the other hand, have the egg whites ready in the bowl where you'll be whipping the meringue.
Make the water with the sugar and Port wine boil until it reaches 116-118℃ (240-245℉). You need a sugar thermometer for this.
When the syrup reaches 110℃ (230℉) start to whip the egg whites at high speed. When the syrup reaches the desired temperature, pour the syrup down the side of the bowl, letting it slide down the side so that it doesn't bounce off the whisk.
Keep whipping on high until it has completely cooled down.
Fill a piping bag with the tip of your choosing and top the base with it. Finish by sprinkling with ground cinnamon.
