To make sugar water:
1/4 cup Rapadura sugar (or honey)
1 quart filtered warm water
Prepare the sugar water for the amount of fruit scraps that you have with the ratio of 1 quart water to 1/4 sugar. Make sure all sugar is completely dissolved. Fill jars with coarsely chopped up fruit scraps about half full, then pour in the sugar water solution. For pineapple vinegar, add the additional spices and stir in. Cover with a towel or cheesecloth and let ferment at room temperature. Stir once/day if you can.
You will notice the liquid darken after about a week. At that point, strain out the fruit scraps and discard or compost them. Ferment the vinegar for 2 to 3 weeks longer, stirring it periodically.
Simple enough right?
