Notes

(NOTE 1) Oysters - In Australia, oysters are often conveniently sold cleaned and already shucked on the half shell. The most important thing when buying oysters is freshness. Always purchase them from a trusted fishmonger and serve them as soon as possible. Fresh oysters should smell clean and slightly briny. Avoid any oysters with a strong or unpleasant odour, as this is a sign they’re no longer fresh.
(NOTE 2) Shallots (Eschalots) - Eschalots look like small, oval-shaped brown onions. They have a milder, slightly sweeter flavour than regular onions, which makes them perfect for mignonette sauce. Finely minced, they soften beautifully in the vinegar without overpowering the oysters.
(NOTE 3) Red wine vinegar - Because this sauce is vinegar-based, using a good-quality red wine vinegar really matters. Cheaper vinegars can taste overly acidic and one-dimensional, which can overwhelm delicate oysters. A good red wine vinegar enhances the sauce, cutting through the richness of the oysters while keeping the flavour bright.
(NOTE 4) Sugar - A small amount of sugar is used to round out the acidity of the vinegar. It doesn’t make the sauce sweet, as it simply softens the sharp edge, creating a more balanced and pleasant finish.
