What are canned cockles and why do they matter?
The cockle (Cerastoderma edule) is a bivalve mollusk buried in fine sand in the Galician estuary. Hand-harvested by Galician shellfish gatherers, they are cooked in their own water and packaged with a saline-slightly vinegared liquid.
Canned cockles are a gourmet product for three reasons: (1) sustainable manual harvesting, (2) size and processing matter more than with other seafood, (3) very high culinary versatility.
Sizes: the 15-20 rule
Size is measured by the number of cockles per can (typically a 110g net can):
- 15-20 pieces: PREMIUM. Large cockles (3-4 cm). €8-15/can.
- 20-30 pieces: High quality. €5-8/can. The most common choice for daily use.
- 30-40 pieces: Standard quality. €3-5/can. For stews or mixed dishes.
- >40 pieces: Basic quality. Small cockles. €2-3/can. NOT recommended as a main tapa.
Rule: fewer pieces = better quality. Large cockles are more expensive because they take longer to grow (the shellfish gatherer has to wait 2-3 years for them to grow).
