To prepare Frog Eye Salad as a gluten-free dish, substitute the standard acini di pepe pasta with a certified gluten-free small round pasta or gluten-free orzo, as acini di pepe is traditionally wheat-based. Additionally, replace the all-purpose flour in the custard with a 1:1 gluten-free flour blend or cornstarch. Ensure all canned and packaged ingredients (including marshmallow creme and mini marshmallows) are verified gluten-free, as some may contain additives processed with gluten.
