One of a growing number of air fryer models in the Tower range, the Tower Vortex 7-in-1 Air Fryer is a combi-steam machine that offers a generous 7-litre cooking capacity, lots of features and functions in a stylish-looking design. It’s a reasonably chunky thing, with dimensions of 42.7D x 31.9W x 38.7H centimetres and weighing in at 6.65 kilograms, so it’ll dominate your worktop if you’re in a galley kitchen. However, the square-ish design lines also means the appliance can be stored fairly easily once it has cooled down and been wiped over. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ You can cook individually, use the same setting on both drawers or, cleverly, use different settings on each drawer but have them synchronise to finish at the same time. There are options to air fry, max crisp (a 240C turbo setting), roast, reheat, dehydrate or bake. General air fryer foods (chips, hash browns, burgers and the like) were cooked exceptionally well, although we did have to add a bit of cooking time beyond the recommend to some food types. Using the grill, we found that its heat was slightly uneven, but moving food around manually when turning it was enough to overcome this problem. That’s why the Tower Vortex 7-in-1 Air Fryer with Steamer is appealing to me, because it can combine air frying with steaming. It's a match made in heaven. Delicate foods, with fish being a prime example, are hard to get right in an air fryer, but the Tower Vortex 7-in-1 Air Fryer with Steamer has proved to be excellent at getting things spot-on.

That means you’ve got a sizeable cooking drawer, that’s square in shape and which can accommodate up to 1.7 kilograms of food in one go. That’s a very decent amount. In fact, it made my collection of meatballs look rather insignificant as you can see from the photo above. Large families will be glad of the extra capacity though. Heat tops out at 200 degrees, so it’s able to handle anything a regular oven would cook.

What makes this product so good is its versatility. As well as Speedi meals, it can also act as a slow cooker, and it can sear food with the lid open. That’s handy for starting ingredients off before slow cooking, or for finishing meals: I cooked rice, and then added some pre-cooked beef strips, onions and peppers, sautéing the food to get it piping hot. This is a proper air fryer, too, although topping out at 210°C it can’t quite get the crispiest of results that air fryers with a higher temperature can reach. I do really like the steam air fry option: this creates perfect chips that are crispy on the outside and fluffy on the inside. Combining and air fryer and grill in one appliance makes a lot of sense: it doubles up of the number of uses and, for the grill in particular, keeps smoke and smells inside the appliance. Mostly, products like this are very expensive, but the Salter Aerogrill is cheaper than a lot of air-fryer only cookers. Air fryers have surged in popularity in recent years as more and more people have opted for this healthier method to create delicious fried food.
