Recently I've been favoring recipes that call for tonno sott' olio - tuna preserved in olive oil. The commercial product available here in the USA is very expensive. Fortunately, it turns out to be pretty easy to make. The tuna still ain't cheap (my tuna was $17.99 a pound so I'm "saving" about $15 versus buying the imported product) but for anyone with a pressure canner or two, it's an interesting change from the annual cycle of vegetable canning that culminates with an orgy of tomato processing in late summer.
There are (at least) three main approaches to making tonno sott' olio at home. One involves a pickling brine with vinegar, salt and various aromatics. Mario Batali has a representative recipe of this type, Fresh Canned Tuna, as does Lidia Bastianich. Note that both these recipes produce a product meant to be refrigerated.
The second approach uses a simple brine: water and salt; the versions differ mainly in the amount of salt used. This is the approach I'm using, as described by Rosetta Costantino in My Calabria: Rustic Family Cooking from Italy's Undiscovered South.
The third approach involves pressure canning fresh, uncooked fish with a little salt and olive oil. Some sources recommend this approach for any fish except tuna, others apply it to tuna as well.
This being SAI's first pressure canning recipe of the season, now would be a good time to drag out your equipment and check it over. I found that the over pressure plug on mine and gotten a tiny cut sometime over the winter - that would have made quite a mess had it blown out.
