Stabilizing Whipped Cream: To do this, add 1/2 tsp unflavored gelatin (this comes in a little box, in the baking aisle at the grocery store) and 2 tsp cold water to a small bowl and let dissolve. Meanwhile, start mixing your whipped cream. Once it just starts to thicken, but before peaks form, stop mixing. Microwave the gelatin for 5 seconds to liquify it, then slowly stream it into the bowl while you beat the mixture on low speed. Once added, continue mixing on medium high speed until stiff peaks form. Now, you can pipe it!
