+Don't toss those pineapple skins! Turn them into a delicious and refreshing Mexican probiotic drink called tepache. It's a great alternative to soda or kombucha and perfect for staying cool in the summer heat. 
+
+Tepache Recipe:
+
+Add the skins of 1 pineapple to a 2L jar.
+
+Mix in ½ cup sugar or brown sugar (piloncillo is typically used but I couldn't find it), 1 inch of ginger, and 1 cinnamon stick.
+
+Fill to the top with water.
+
+Let it ferment for 5 days.
+
+Bottle it up for a second fermentation for 2 days. Then, chill in the fridge before serving.
+
+Enjoy this bubbly, homemade treat!
