These little beauties might look unassuming. But trust me, they punch hard. Their flavour is rich and briny, with that deep satisfaction that comes from chewing them slowly, almost like a ritual. Usually boiled, they can be addictive. Once you try them, you might develop a constant craving for them — just like I did.

Don’t let the name fool you: these are not your average clams. They get their crimson hue from their haemoglobin content, and that’s also where that unique, iron-tinged minerality comes from — the thing that sets them apart from anything else you’ve ever tasted by the sea.

And the texture. Firm and meaty, with just the right amount of resistance to give your jaw a proper workout. Worth every bite, trust me.

Served with a spicy sauce that burns just enough, they are the perfect companion to a cold beer or a fiery bowl of tom yum. Be bold. Try these little things. Your taste buds will thank you.
