Most of our products are fully cooked and ready to eat. You can find cooking instructions either on the product pages on our site or directly on the packaging. Our meals come in vacuum glass jars which are microwave safe. Before warming you need to open the glass jar to break the vacuum. To open a jar: hold the lid of the jar with one hand and pull the tab straight out (not up) with the other hand. To heat the food, remove the rubber ring, warm the food (lid on or off) directly in the glass jar either using a microwave or an oven. You can also transfer the food into a small pot and heat it on the stove top. You may want to add a sprinkle of water when heating meals to retain consistency and creaminess. Tip: You can also heat the meals in the morning and transfer them to a thermos to keep the food warm for a few hours so that your child can take them to nursery.
