Using Ferino's Bibingka Rice Cake is a breeze. Just pop it in the microwave as per the instructions on the package, and in minutes, you'll have a warm and delicious treat. As it's a frozen product, make sure to keep it in the freezer until you're ready to use it. When handling the cool shield thermal packaging and the frozen gel ice packs, don't worry as they're non - toxic. But remember, don't reuse the ice packs for food storage if they've been damaged. And enjoy this cake right away after heating for the best taste and texture.
