If it is packaged, you can eat it directly (although it may be unacceptable from our eating habits for a while, caviar is raw and loses its unique taste when cooked) because it is already a processed "caviar", but it may be fishy and salty when you eat it for the first time, but it will be fine after eating it a few times. That unique taste is really memorable.
If you take it out directly, it should be a large piece of fish eggs stuck together and stuck to the egg membrane. It is suggested to soak in white wine first (it should be called wine stain or wine stew), tear it into small pieces with a knife or directly by hand when eating, and dilute the green mustard with vinegar (also called green mustard, Japanese mustard and horseradish, in short, you should understand), or just put mustard directly and pour vinegar like Japanese cuisine. Processed caviar can be eaten like this.
I tried a "loser" eating method myself, that is, eating too much oil (because I started to be more resistant to raw food), and then half a cup of oil was ruined by me, which was very fishy. However, the fish seeds are delicious, not fishy or bitter (but the French devils and Russian people should cry).
Also, liquor is necessary for both Japanese and Russians, especially when they are not used to the fishy smell of fish eggs at first (think about why Japanese want sake and Russians want vodka). Later, white wine can keep the heat and fragrance in your mouth, so you must have white wine if you want to eat fish eggs.
It's been so many days and nothing has happened. The landlord deliberately didn't want to give points.
