Cook beans in boiling water for 4 minutes. Drain. Place in a large bowl of ice water. When cool, wrap in paper towels, place in a plastic bag and seal. Refrigerate up to 2 days. To reheat, place beans and butter in a large frying pan set over medium heat. Stir constantly until hot, from 2 to 3 minutes. Stir in salt, pepper, mint and almonds, if using.
