An electric current with 40 to 80 volts is applied to a mixture containing cut onions, 0.1 to 10% by weight of sea salt and 0.1 to 10% by weight of methionine, the onion mixture is then fermented at 20 to 35deg.C for 2 to 5 days in the first step. Thereafter, 10 to 40% by weight of the onion mixture is mixed with 60 to 90% by weight of herbs, fermented at 20 to 35deg.C for 2 to 5 days in the second step.
