To understand the relationship between aquavit and lutefisk, here's an experiment you can do at home. In addition to aquavit, you will need a slice of lemon, a cracker, a dishtowel, ketchup, a piece of lettuce, some caviar, and a Kit-Kat candy bar.
1. Take a shot aquavit. 2. Take two. (They're small.) 3. Put a bit of caviar on a bit of lettuce. 4. Put the lettuce on a cracker. 5. Squeeze some lemon juice on the caviar. 6. Pour some ketchup on the Kit-Kat bar. 7. Tie the dishtowel around your eyes.
If you can taste the difference between caviar on a cracker and ketchup on a Kit-Kat while blindfolded, you have not had enough aquavit to be ready for lutefisk. Return to step one.
