Lately I have been experimenting with new molecular recipes and this is one of the recipes I created. One of my best friends loves when I make caviar for molecular recipes and he kept urging me to make caviar with soda. I decided to tried it and it worked really well. This makes a beautiful small appetizer for formal parties and other events. The two food additives you will need for this recipe are agar agar and soy lecithin. I use agar flakes which can be purchased at whole foods and the soy lecithin that I use was purchased from amazon.com for about $8.00. You will aslso need an oil for this recipe. I prefer to use olive oil because it freezes fast but any kind will work. All of the oil will wash off so the quality of the oil doesn't matter. Enjoy!
