The basic rules for choosing onions:

  • The onion must be heavy enough (if the weight of the onion does not match its size – inside it may be dry or infested with parasites);
  • there must not be any spots, dots or traces of insects on the skin and surface of the bulb (there must not be any mechanical damage or cracks on the bulb as well);
  • the surface of the onion must be dry and sufficiently hard;
  • the lighter the onions, the hotter they taste;
  • red onions store less than white and golden onions (this nuance must be taken into account if you buy onions for long storage);
  • onions should have a weak and not acrid flavor (the aroma should be onion and not contain any extraneous odors);
  • the husk of onions of any variety should be shiny (lack of shine indicates low quality onions, their excessively long storage or improper transportation conditions);
  • onions should not have any moist spots (if such spots have a pungent smell, the onion is definitely spoiled);
  • the optimal size of a good onion can be between 3-5 cm (other variants may have compromised flavor characteristics);

  • don’t buy onions if the heads are too big or too small (chemical components are likely to have been used);
