You can make pasta from whatever fish you like, from a single type or by combining different fish. I don't make pasta from one kind of fish, ever. I use canned fish in oil and try to put in several kinds: smoked sprat (I build this paste around it, if I don't have it, I don't make it), tuna, mackerel, sardines, whatever.
- Open the can of smoked sprat and put all the contents, fish and oil, in a glass bowl.
- You take the others apart one by one. Put only the fish in, drain the oil before pouring the fish into the bowl. The oil can also be used for salads.
- Mash the fish with a fork until it becomes a paste.
- Add the butter and mix well.
- Squeeze half a lemon and gradually add as much juice as you like.
- Chop the onion finely and stir into the fish paste.
- Season: cayenne pepper (we eat something hotter) or black pepper, red pepper, whichever you prefer. I also add a little turmeric and paprika.
- No need for salt, the cans are salty enough.
Serve on crackers or toast. Keep refrigerated.
