There is a fairly well known recipe for Triple Cooked Chips. It involves cooking chips three different ways / times.
Is triple cooked correct or should it be called Thrice Cooked Chips as they have been cooked three times?
Pretend it would concern the number two instead of three:
Use thrice when you would use twice.
Use triple when you would use double.
As they have been cooked three times, I would suggest “thrice”.
For comparison: I have seen you triple today. Doesn’t work, does it?
