I find the French dressings and most ready-made salads (with dressing) from Migros too vinegary or too acidic. Is it because the cheapest brandy vinegar, i.e. "chemical" vinegar, is used instead of natural vinegar? The most striking example: Anna's Best chicken salad makes my mouth water with acidity, whereas the comparable product from Denner tastes wonderfully fruity/creamy and not at all sour.
