The most important thing that you must pay attention to in order to have success with this our Low FODMAP Peanut Butter & Jam Hearts is the type of peanut butter that you buy and use in this recipe. We have an Explore An Ingredient: Peanut Butter article for you that explains all the different types of peanut butter and how they differ in taste, texture and how they work in recipes.   This recipe calls for the “no-stir” style (see below). This kind of peanut butter is very creamy – especially the smooth type, as opposed to chunky. The ingredients will list peanuts, palm oil, salt, and sugar. The palm oil and sugar create a very creamy, smooth product that works more similarly to the type of peanut butter that contains hydrogenated fats when used in baking recipes. Natural peanut butter will not work in this recipe.   Palm oil is low FODMAP, FYI.
