The tins I have suggested in this book are only suggestions but if you don’t have a great variety I would recommend as essential one 25cm (10 in) tart ring, one loaf tin and one 21cm (8in) springform tin. These will cover most types of cakes. Loaf tins are great for heavier type cakes, such as pound or fruit cakes, while springform are my preference for lighter and layered cakes. The greater the variety of tins of all types you have - tart rings, springform cake tins, loose-bottomed tins, loaf tins, tray bake tins, muffin tins, baking trays - the bigger selection of cakes you can bake. It really comes down to personal preference which ones you bake with, but for longevity it makes sense to invest in those made of good-quality stainless steel.
