Sardine Butter. Does the combination of these two words have you salivating or grimacing? Canned sardines  are a delicious, nutritious fish, but they aren’t everyone’s favorite. The flavor can be a little, well, fishy. But there are a lot of omega-3s and other nutrients packed into those small, oily little fish , so finding a way to love ‘em is a worthwhile endeavor.
Butter, on the other hand…who doesn’t love butter? Mashing butter and canned sardines together with lemon and cayenne makes a simple but stunning spread. Sardine butter has a more assertive, less delicate flavor than anchovy butter . But sardine butter is much less “fishy” than sardines straight out of the can (if that’s a plus for your taste buds).
In recipes like this, with so few ingredients, quality matters. Use your favorite salted butter, hopefully one that’s pastured  or cultured. Grab a few cans of sardines from the grocery store, taste-testing to find you favorite. Boneless sardines give the butter a smoother texture, but if you don’t mind a little crunchiness (and want the calcium) then go ahead and use bone-in. Whether they’re smoked or un-smoked, packed in water or olive oil, is your choice.
Sardine butter can be spread on your favorite Primal cracker , or on the Parmigiano-Reggiano & sesame crisps included in the recipe below. Sardine butter is fantastic spread on raw, crunchy veggies like radishes or dolloped onto warm roasted vegetables.
