  1. Hi Laura,
    Just about to try your Marshmallow sauce but we’re a little unclear to the size of the Marshmallows you use,
    Managed to get hold of American Style giant Marshmallows 🙂 which are about 2” long and 2” wide. I guess bigger than the ones you used (maybe). So your recipe of 24 Marshmallows seem excessive for that size Marshmallow but grateful for your advice.
    Greetings from London by the way 😄

    • Hi Jeffrey, The size of marshmallows I used are about 1-1/4″ long and wide – the most common size here in the U.S.. They are not the giant marshmallows. You might try around 18 of the giant marshmallows to get you close to the recipe. I appreciate your comment!
