Preheat oven to 400ºF. Cut baguette into 12-inch slices. Lay bread slices on a baking sheet and place in the preheated oven. Bake for 5 to 6 minutes.
(The bread does not need to brown, just have a toast-like crust on the top surface.) Remove from the oven. Leave bread slices on the pan and rub garlic cloves on the toasted surface. Peel the white rind from the brie and discard; slice brie thinly and place slices on top of the toasted bread. Return pan to the oven for 3 to 5 minutes, just until brie has melted. Place a teaspoon of arils on each slice and press down with the back of a spoon. Serve this pomegranate recipe immediately while warm.
