Place the day-old bread pieces in a bowl and pour in the cup of water. Let soak for 20 minutes.

After 20 minutes, transfer the soaked bread and water to a blender. Add the almonds, vinegar, salt, olive oil, and peeled garlic clove.

Blend everything until smooth. You can strain the mixture for a smoother texture or leave it as is.

Pour into bowls and chill in the refrigerator until cold.

Before serving, drizzle with a little olive oil.
