A local colleague showing me the way to twirl the meaty foot out of the shell of freshwater apple snails at a beer cafe in Hanoi. I suspect that this may be a local variety. Vietnamese farmers are waging an on-going but ultimately lost battle with larger introduced species that are ruthlessly chomping their way through the country's rice and taro crops. Unfortunately and typically, the aliens are not so tasty and not favoured as food.
The apple snails were wok steamed with lime leaves, chilli and lots of lemongrass. It took me but a moment's hesitation before joining my enthusiastic dining companions in digging in, or should that be digging out! Tastewise the somewhat chewy meat had obvious hints of earthy...erm...'algaeness' but this was easily fixed by a vigourous swirl in lime juice mixed in with peppered salt. Not so much a fan of the pulpy 'tail' and innards that trailed out after the foot however. The only culinary descriptive I could come up with on this was..."eww"!
