Finely mince the red onion.
In a small bowl, mix together the capers, caper juice, and minced onion. Chill for at least one hour to develop flavor.
Preheat the oven to 375°F.
Use a serrated knife to cut the baguette into ½-inch thick slices.
Arrange the slices on a baking sheet, then lightly brush each slice with olive oil.
Toast the bread until crispy and just beginning to brown, about 10-15 minutes.
When the crostini have cooled, spoon about a quarter to half tablespoon of cottage cheese onto the center of each toast (reserve half of the toast for Gollum's Tartine, if making).
Place a piece of lox on top of the cottage cheese, then sprinkle about a half teaspoon of mignonette onto each toast.
Garnish each toast with a tiny sprig of fresh dill.
Serve right away while marathoning Lord of the Rings. Enjoy!
