A good blend of seasoning is most important, so I am going to give you a French housewife's secret.
Mince onions very fine, then place in a bowl and add salt, paprika, thyme, sweet marjoram, sage, cloves, and allspice. Rub together until thoroughly mixed and then put in a warm dry place for twenty-four hours. Put through a fine sieve. Place in a bottle and use one teaspoon of this mixture in place of salt.
