Rinsing feta cheese isn’t typically necessary and can actually dilute its flavor. Feta cheese usually comes in brine or a sealed container, and it’s best to use it straight from there to preserve its tangy, salty taste. If you find that the feta is too salty for your liking, you can give it a quick rinse under cold water, but be sure to pat it dry thoroughly before using it. For most recipes, including this one with sliced tomatoes, using feta straight from its packaging will provide the best flavour and texture, allowing it to complement your dish perfectly without compromising its distinct taste.
