Making marshmallow fluff at home is totally worth it. The texture is like a cloud and if you pipe it, it holds its shape better. This technique is similar to making Italian meringue and, as long as you have a candy thermometer, you should fear nothing.
Earl Grey compliments it nicely and makes it fragrant of bergamot. Garnish any lemon dessert with it to add the floral, creamy flavor. If you own a blow torch, have fun.
