If your mussels are frozen, then you do not need to defrost, just rinse with cold water. In a pan, mix soy sauce, lemon juice, vegetable oil, add bay leaf, salt, sugar and pepper.
Add hot water to the pan, boil and pour the mussels, cook for 2 minutes. Remove from heat.
Chop the garlic and dill with a knife.
Add the dill with garlic to the pan, just put the chopped lemon.
Leave the mussels in the marinade to cool. Then refrigerate overnight.
