Yes, modifications can be made to this Lemon Balls recipe to accommodate gluten-free or vegan diets. To make the recipe gluten-free, substitute regular flour with a gluten-free flour blend, such as almond flour or a mix designed for baking. It’s essential to ensure that the other ingredients, like baking powder and vanilla extract, are also gluten-free. For a vegan version, replace the eggs with a suitable egg substitute such as flaxseed meal (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water equals one egg) or silken tofu. Additionally, ensure that the sugar used is vegan, as some sugar is processed using bone char. These alternatives can help maintain taste and texture while catering to dietary preferences.
