Adjust amount as and let them steep. It's all about experimentation. Not all flavoring are created equal. Some are very strong and others are weak. You just need to add small amounts at a time. Keep in mind that steeping can help as well so theres a lot to consider. I would suggest add more steep for a few days or steep in hot water and taste. If you can't do anything with the flavor go on to the next flavor. Don't keep knocking your head aganced a wall if the flavor don't work out because all that accomplishes is giving you a headache.
