Oyster Thief / Sea Cauliflower

Description

Wild-Foraged • Cape Cod, MA

A buoyant, brain-like green seaweed found drifting in Cape Cod’s protected bays and channels, Oyster Thief — also called Sea Cauliflower — is a close relative of Dead Man’s Fingers but with a more rounded, clustered structure. Light, spongy, and naturally salty, it brings a clean ocean flavor and striking visual appeal to coastal dishes.

Flavor & Texture
Clean, mild ocean salinity with subtle sweetness
Spongy, airy texture similar to Codium but lighter
Holds its shape beautifully when blanched or fried
Absorbs marinades and broths extremely well

How I Harvest
Collected by hand from drifting clusters or lightly attached tufts in calm nearshore waters. Because this subspecies often grows free-floating, harvesting it requires careful timing with tides and winds. I only gather fresh, vibrant green clusters and avoid any over-harvest from attached patches, protecting Codium beds and local shellfish habitat.

Seasonality:
Most abundant from late spring through early fall, especially after periods of warm, calm weather when floating clusters become more common.
