Marshmallows are the sugar-and-gelatin candies that anchor rice krispie treats, s’mores, rocky road desserts, and most no-bake American treats. Mini and standard sizes have specific best uses. Mini for melt-into-batter applications, standard for s’mores and topping. Marshmallow favorites include Caramel Rice Krispie Treats where the marshmallows either melt to become the binding agent (rice krispie treats) or stay whole as a finishing topping.
Mini marshmallows and standard marshmallows behave differently in melting applications. Minis melt faster and more evenly into a smooth mass, making them the right choice for rice krispie treats and chocolate fudge applications. Standard marshmallows take longer to melt and can leave lumps if rushed. For visible-marshmallow applications (s’mores, hot chocolate topping, sweet potato casserole topping), standard size is what most American eaters expect.
The standard rice krispie treat ratio is 3 tablespoons butter, 1 (10 oz) bag of marshmallows, 6 cups rice krispie cereal. Melt the butter and marshmallows over low heat (high heat produces tough, chewy treats rather than light, soft ones), stir in cereal, press into a buttered 9×13 pan. Cool 30 minutes before cutting. The whole process takes 15 minutes.
For s’mores indoors (the year-round version), the technique is to place a graham cracker on a sheet pan, top with a chocolate square and a marshmallow, broil 30-60 seconds until golden, top with second graham cracker. graham crackers and chocolate combine with the toasted marshmallow’s residual heat to produce the campfire experience without the fire.
For storage, opened marshmallow bags should be sealed tightly in zip-top bags with the air pressed out. They keep 2-3 months at room temperature; longer storage causes them to dry out and become hard. Stale marshmallows can be revived by storing them with a slice of bread for 24 hours. The bread’s moisture migrates to the marshmallows. chocolate pairs particularly well with marshmallow in nearly every American dessert application, from rocky road ice cream to fudge to hot chocolate toppings. Other reader picks that build on marshmallows include The Ultimate S’more Cookie Bars and Shortbread Cookie Bars. Browse chocolate, graham crackers, and salt for closely related cooking applications.
