How many drops of peppermint extract for 1 cup of tea?

For one cup of tea, you typically need about 1/4 to 1/2 teaspoon of peppermint extract, which is roughly equivalent to 4 to 8 drops, depending on the strength of the extract and personal taste preference. Start with 4 drops and adjust to your liking, as peppermint extract can be quite potent.
