The Instant Marinator is a unique dish that marinates and tenderizes all types of meat, fish, poultry and vegetables in just minutes. Simply add your marinade to the food in the dish and them pump out the air to create a vacuum. The vacuum opens up the pores and fibers of the food allowing the marinade to penetrate in minutes rather than hours "locking in" flavor. It also tenderizes the food and keeps it juicy. The vacuum dish can also be used to store your food under vacuum to preserve flavor and freshness. Easy to use. Saves time. Dishwasher safe. Suitable for freezer and refrigerator storage.
