You can smell the flavours of the sea from a couple of metres away. (plenty of salty, scampy scent) as the family that owns this little shop still do it the old way. They sun the shrimps and put them into large ceramic jars to make a sauce, then they dry it outside to make a bar of shrimp paste and the rest they bottle.
They may be the snappiest and grumpiest shopkeepers in Macau, at times really rude and nasty, but their shrimp paste is the real thing, and worth having them bark at you. 40MOP a bottle and the bar of shrimp paste slightly cheaper.
