What Are Crack Seed and Li Hing Mui Snacks?

Updated

Crack seed is a category of preserved or dried fruit snacks — most often plums — seasoned to hit sweet, salty, and sour notes at once. Li Hing Mui is the best-known example: a dried plum treated with li hing powder, which gives it a tangy, sweet-salty flavor. Both are chewy, intensely flavored, and a long-standing local Hawai'i treat. If you like sour candy, salted dried fruit, or savory-sweet snacks, this family of snacks is worth trying.

Crack seed vs. Li Hing Mui: what's the difference?

"Crack seed" is the umbrella term; "Li Hing Mui" is one specific snack inside it. The name "crack seed" comes from Chinese preserved seeds and fruits that were cracked open to eat — over time in Hawai'i it came to describe the whole style of preserved, seasoned fruit.

Crack seed Li Hing Mui
What it is General category of preserved/dried fruit snacks A specific dried plum snack
Core flavor Sweet, salty, sour, sometimes licorice-like Tangy, sweet-salty, with a distinctive plum-powder zing
Texture Chewy, sometimes leathery Chewy, slightly sticky
Typical base Plums, seeds, fruit strips Dried plum coated in li hing powder

Li hing powder (made from dried plum skin, often with licorice and other flavorings) is the seasoning that defines the Li Hing flavor — and it shows up well beyond plums.

What do they taste like?

Expect a bold, layered bite rather than a simple sweet or sour one:

  • Sweet from the fruit and added sugar
  • Salty from the curing process
  • Sour/tangy from the plum itself and the li hing powder
  • A slight licorice-like note in many li hing products

The combination is why these snacks are often described as "addictive" — each piece pushes several taste buttons at once. They're usually eaten straight from the bag as a snack, and li hing powder is also sprinkled over fresh fruit, shave ice, and gummy candy.

Common varieties you'll see

Beyond straight Li Hing Mui, the same flavor family covers a wide range:

  • Sweet Li Hing Mui — the sweeter, less aggressive version of the classic
  • Seedless Li Hing Mui (white or red) — same flavor, no pit to work around
  • Rock Salt Plum — saltier, more savory take on preserved plum
  • Seedless Plum — plain preserved plum without the li hing coating
  • Li Hing Mango (wet) — dried mango with li hing seasoning
  • Li Hing Gummy — gummy candy coated in li hing powder
  • Cracked Seed — the classic preserved seed/fruit style
  • Arare — small crunchy Japanese rice crackers, often eaten alongside or mixed with these snacks

If you're new to the flavor, a sweet or seedless Li Hing Mui is usually the gentlest entry point; rock salt plum and straight li hing are for people who already know they like the salty-sour end of the spectrum.

Where to buy them

Crack Seed Center (crackseedcenter.com) is a Hawai'i-based shop that has been selling these snacks since 1959, according to the site. Its listed best sellers include Sweet Li Hing Mui, Jumbo Sweet Li Hing Mui, Seedless Li Hing Mui in white and red, Rock Salt Plum, Seedless Plum, Li Hing Mango (wet), and Cracked Seed, with prices shown as starting points (for example, Sweet Li Hing Mui from $6.00 and Seedless Plum from $4.75). The site also groups products into Plums, Arare, and Li Hing Gummy sections and ships by country/region selected at checkout.

If you're ordering for the first time, a small selection across the categories — one plum, one mango, one gummy, one arare — is a practical way to find which end of the sweet-salty-sour range you actually like.
