This would also be a great thing to include in a
Secret Sister card. But since you are trying to keep your identity a secret, make sure you write, "From the Kitchen of Your Secret Sister," rather than including your name.
Another thought is to include this as part of your Secret Sister Reveal Party! Have everyone fill out one of the recipe cards to give to their Secret Sister! They would be able to include their name on it since they are revealing their identity at this party.
Also, if you will be attending a potluck this year, why not have some recipe cards filled out to give to people who comment about the delicious food you brought,
I hope you are able to enjoy using these free printable recipe cards. Print them off as many times as you'd like, if you have recipes to share with friends, family, coworkers, neighbors, etc.
