How to reheat creme brulee to maintain its delicious texture and crispy caramelized topping?

To reheat creme brulee while maintaining its texture and crispy topping, use a kitchen torch to gently re-caramelize the sugar on top. This will help preserve the crunchiness of the topping and keep the custard creamy. Avoid using the oven or microwave, as they can make the custard rubbery and soften the topping.
