Kit I use and recommend.

Ninja Crispi 4-in-1 Air Fryer

Genuinely incredible. It's quick and convenient, small enough to store, but big enough to cook multiple portions.

Worth knowing: The plastic base isn't detachable, so the outside of the glass is fiddly to clean.

Used in: Crunchy Rainbow Salad with Roasted Chickpeas & Feta, Sticky Hoisin Chicken Thigh with Sweet Potato & Tenderstem, Red Cabbage Rice & Sticky Chicken

Morphy Richards stainless steel pan set

Why I only use stainless steel: it's affordable, it lasts for years, and there's no non-stick coating, so no PFAS (the 'forever chemicals' used in non-stick pans). This set is no longer sold. If you're buying, look for a thick, multi-layer base so it heats evenly, and check it works on your hob.
