Do I need to rinse canned sardines?
Not usually. If they are packed in olive oil, you can use a little of that oil in the dressing or drain it and use fresh. If they are packed in water, drain and gently pat dry so the dressing does not get watered down. A quick rinse is optional, but it can wash away flavor.
What sardines should I buy?
Look for boneless, skinless if you are sardine-curious. If you already like them, skin-on, bone-in tends to be richer and more traditional. Either works here. If you use bone-in and spot a visible backbone, you can lift it out easily before serving if you prefer.
Can I make this less salty?
Yes. Use sardines packed in water, add extra cucumber, and go easy on added salt. A little extra lemon juice also helps balance saltiness.
Is this safe to serve cold?
Yes, as long as you keep it refrigerated and follow normal food safety. Once opened, refrigerate and eat within a day or two, and always follow package guidance if it is more specific.
Can I turn this into a full meal?
Absolutely. Add cooked white beans, a handful of arugula, or sliced tomatoes and call it dinner. I do it all the time.
Any allergy or diet swaps?
Fish is the main allergen here, and bread adds gluten. For gluten-free, use sturdy gluten-free crackers or serve with cucumber rounds and beans.
