Shiso Sour Cream: Tangy shiso and creamy sour cream are the perfect pair for this addictive flavor. About Pom Pom Popcorn: Pom Pom Popcorn was first created at Bessou, my Japanese American eatery in NYC. We wanted to share the delicious flavors of Japan using the most iconic American snack: popcorn! Taking our favorite childhood treats as inspiration, we use real ingredients in everything and make our popcorn in small batches so you can taste the love, care and flavor in every bite. The result is delightful, healthier snacking. Arigato!
