This is from Modernist Cooking and here's what they say,"One of the easiest ways to try out molecular gastronomy is by creating "pearls". Most pearls are solid jelly balls that can be used to garnish dishes or as an amuse-bouche. Here we create sweet-sour balsamic vinegar pearls that are a great way to add a hit of flavor to many different dishes. The process of making them is even pretty easy. We first combine the vinegar with agar agar and bring it to a boil. Then we drizzle it into very cold olive oil that chills the droplets into spheres before they reach the bottom of the glass. Once you rinse off the balsamic vinegar pearls they are ready to use or you can store them in the refrigerator for later use." You can see their video on how to make pearls here: http://www.modernistcookingmadeeasy.com/info/modernist-recipes/more/balsamic-vinegar-pearls-recipe I saw Tyler Florence's general recipe for these pearls and got the exact measurements off the internet. Have fun!
