I’m going to try your sardine recipe. I have all the ingredients :-)
As a newcomer to anchovies, I will try the other suggestions here going easy on the anchovies. I do have several tins of them, for whatever reason that I can’t remember now. But I’ve been hesitant to try them.
Don't worry, they hardly ever explode. Most anti-anchovy types whine about the salt content, though.
You can easily reduce the salt content, if you like. Rinse off the oil from the tins and soak the fillets in water for 5 minutes to 30 minutes, depending on how much salt you want to remove. Separate each fillet from the others before soaking them. After soaking, just discard the water.
If you fancy sardines, you'll like the paste very much.
Buena comida a ti!
