This 400 g bag of extra‑large mushroom popcorn kernels from Joe & Seph’s is ideal for anyone looking to “make‑your‑own” gourmet popcorn. The special mushroom‑style kernels pop into round, dense, fluffy corn with a large surface — perfect for coating in caramel, chocolate or cheese — and produce popcorn that stays crunchy longer and resists crumbling.
