Salter's glass air fryer rivals the Ninja crispi – but costs less than £100

★★★★★What we love: Easy to set up with two differently sized glass containers and lids for storage, seven functions and high heat, easy to clean and cooks chicken to perfection Take note: Mixed results when cooking vegetables and steep price “The Crispi is a wonderfully versatile bit of kit. With its seven different functions, it’s hard to find a task it isn’t suited to. There are two glass canisters – a big 5.7L one, and a smaller 2.3L one – and setup is easy. The fact it can go up to 240 degrees, 40 degrees higher than most other air fryers on the market, gives it an edge in crisping, frying and grilling your food. One big bonus to the all-glass container is being able to see the food cook in real time. And it’s also helpful when it comes to cleaning – there’s nowhere for dirt to hide, and the most stubborn stains can be lifted with a warm water soak.Food can be stored in the containers, which also came with lids, allowing me to put them in the fridge without even transferring them to another box. Roast chicken was cooked to perfection, while vegetables were more of a mixed bag (string beans were plated crispy and delicious, but the broccoli was charred, and the carrots were raw). One surprise winner? Reheated pizza. Though the price is high, the fryer is so good that it genuinely feels like it could replace your oven, and maybe your hob too. The cooking (once you’ve set things up) is simple, the clean-up is simple, and the design looks wonderfully chic sitting on your countertop. And the two different-sized baskets mean that cooking for one, or for a family, feels equally easy. A winner.” Capacity: 5.7l Wattage: 2,050WTemperature range: 40-240°C
