Tuna sandwiches are a lunchtime staple, prized for their protein, Omega-3 fatty acids and vitamin D. While mayonnaise is the traditional partner to add moisture, some food experts suggest swapping it for sour cream to elevate the flavour.
Why sour cream works better
Sour cream offers a slightly sweet tang that enhances the tuna's taste without overpowering it, while delivering a creamy and smooth texture. Compared to mayonnaise, it is generally lower in fat, making it a slightly healthier option that still provides a rich taste.
Food and drink brand Tasting Table noted: "While the mayo's custardy, egg tones are typically expected, you'll find sour cream's sweet, creamy medley to be just as (if not more) satisfying."
Flavour and texture benefits
Both mayonnaise and sour cream share a tangy flavour base, but sour cream's milky richness brings a refreshing element to tuna salad. The fish's usual salty, savoury taste becomes less dull and is balanced by an equal amount of deep and bright flavours.
Tasting Table added: "Even better, with sour cream's consistency, there's also a textural shift that makes for a much better eating experience. Everything comes together beautifully on the taste buds — the fish's tender yet chewy bites and the veggies' slight crunchiness, all coated in the sour cream's velvety thickness."
How to make the swap
Food.com recommends combining one tablespoon of sour cream (regular or low-fat) with 5oz of tuna in a bowl and mashing it together. For extra flavour, add a pinch of salt and black pepper and one teaspoon of mustard, though the mustard is optional.
Once combined, more sour cream and mustard can be added according to preference. Serve the tuna salad in a sandwich, garnished with slices of cucumber, tomato and lettuce for freshness.
